File Name: Wolfeh's Loading Screen Tutorial File Submitter: Wolfeh File Submitted: 18 Aug 2016 File Category: Other Graphics This probably isn't the best guide out there, but I'm hoping it will help some. It goes through how I made the loading screen in the preview, as well as just a small guide on how to implement these things. It's pretty basic and easy but may help those who are new to photoshop learn how some things work. It covers basic text editing, photo adjustments, and how to apply brushes. The two pdf's in it are for you to learn from and use, you can do anything with them since I don't plan to use them. Same with any and all images in it as well.

Now Before we delve into the details, lets consider a few things - this is meant for newbies. If you have made patches before skip ahead. Introduction to patching When we say we patch a client what it means is we change few bytes with a different set of bytes. (essentially we change a few opcodes or assembly instructions for e.g. a JNE to JMP so that the client behaves differently) Now these codes will be different for each client date and/or their location will change. So how do we make it generic? For this you need a sort of flow-chart to follow to get to the locations where modification needs to be made and for getting the replace logic. If you know how the original bytes were found , try to make note of the procedure you followed and you can usually make a patch following same logic. For e.g. like find a string -> find where its pushed -> 8 bytes later there is a JNE -> change to JMP Another step that helps out is finding a common pattern in a set of clients around where your modification is to be done. For e.g. Lets say i find '75 C0 E8 09 22 04 00 68 44 65 97 00' in 20130612 and '75 C0 E8 10 23 04 00 68 54 44 98 00' in 20130626 common pattern => '75 C0 E8 ?? ?? ?? 00 68 ?? ?? ?? 00' where ?? can be anything so you can use this common pattern instead of the individual ones. Not sure whether I made it clearer or confused you with that Intro. To summarize - making a patch is a combination of finding byte patterns, finding referenced addresses, changing instructions, finding vacant spaces and adding new codes, updating calls etc. If you know assembly language then it should be easy for you. If you don't know already try to read up on it at-least a little before going forward Now then back to topic Patches in NEMO The patches for NEMO are written in QtScript which follows ECMAScript format guidelines same as ... Javascript Therefore almost all of the functions & behaviors offered by Javascript you will find is also there in QtScript (well except for the actual web development part ) So I am not going to concentrate on the language itself. But rather I would be focussing on What all aspects are there specific to NEMO. NEMO Patch Instructions For NEMO to recognize a patch it needs to be registered. This is done in _patchlist.qs file in the patches folder. FORMAT for registering patch : registerPatch(patch id, functionName, patch Name, category, group id, author, description, recommended [true/false] ); patch id - a unique number used for referring to the patch internally in NEMO. functionName - the name of the function which will be called when a patch is enabled in NEMO. This function will contain your logic for making modifications into the client. patch Name - Name of the patch (displayed in the table) category - Category of the patch (like UI , Data, etc. displayed in the table) group id - id of the registered group to which this patch will belong. (details below) author - Patch Maker's Name (displayed in the table) description - Description of what the patch does (displayed in the table) recommended - boolean value showing whether this belongs to the recommended list of patches. Each Patch will belong to a Patch Group (if its not supposed to be part of any specific group use group id 0). All Patch Groups must be registered before they are used (except for 0 which is the Generic Patch Group registered by default) FORMAT for registering group : registerGroup(group id, group Name, mutualexclude [true/false]); group id - a unique number used internally in NEMO as well as when registering a patch. group Name - Name of the group (displayed in the table for all member Patches) mutualexclude - boolean value determining whether member patches are mutually exclusive i.e. Only 1 can be selected at a time or not. Once a patch is registered you need to make the function (name specified while registering). You can make it in any .qs file and save it in patches folder. It will be read automatically. Now to facilitate writing patches there are some ready-made variables & functions available to you. Now to facilitate writing patches there are some ready-made variables & functions available to you. 1) Reserved Keywords (well in a sense) i) Section Types - The following four can be used for referring to a section instead of using the section name itself as an alternative. CODE = 0, DATA = 1, IMPORT = 2, DIFF = 3 ii) User Input Types - These are the available input types in NEMO that you need to specify while getting an input value from user with the getUserInput() Function. Based on the types a different prompt appears for the user to select the value. You will understand more once you see function later on. XTYPE_NONE = 0, XTYPE_BYTE = 1, XTYPE_WORD = 2, XTYPE_DWORD = 3, XTYPE_STRING = 4, XTYPE_COLOR = 5, XTYPE_HEXSTRING = 6, XTYPE_FONT = 7, XTYPE_FILE = 8 iii) Pattern Types - You can specify a string in two forms : PTYPE_STRING => 0) Regular C Style string with Null termination - i.e. anything after '0' or "x00" will be ignored. E.g. "Ragnarok" PTYPE_HEX => 1) Hex String with spacing - You specify each byte with a space prefixed before it. E.g. " 68 90 00 95 00" As you might have guessed already if you have a null byte in your hex string always use PTYPE_HEX. iv) Address Types - Currently it is only used in findString() function to specify the type of value you want returned RAW = 0, RVA = 1 i.e. RAW/real address or Relative Virtual Address 2) Global Variables APP_PATH = path where NEMO is run from. CLIENT_FILE = path of the currently loaded client exe. Whenever your client exe gets loaded the object gets updated to refer to the loaded client. To access the bytes inside the exe we make use of the various methods of this object (Client Access functions detailed below). 3) Client Access Functions 3.1) - Fetching data i) exe.fetchByte(offset) - Extract 1 Byte and return it as a signed number. ii) exe.fetchWord(offset) - Extract 2 Bytes and return it as a signed number (little endian) iii)exe.fetchDWord(offset) - Extract 4 Bytes and return it as a signed number (little endian) iv) exe.fetchQWord(offset) - Extract 8 Bytes and return it as a signed number (little endian) v) exe.fetch(offset, num) - Extract <num> Bytes and return it as a string ( PTYPE_STRING ). vi) exe.fetchHex(offset, num) - Extract <num> Bytes and return it as a hex string ( PTYPE_HEX ). Do note that the returned hex string will already have space prefixed. 3.2) - Searching for data i) exe.find(pattern, type, useWildCard = false, wildCard = "xAB", start = -1, finish = -1) This is the core searching function available in NEMO. All the others are just extended versions of this function. This function searches for the <pattern> you provide in the client between the <start> and <finish> offsets. You need to specify the pattern <type> (PTYPE_STRING or PTYPE_HEX) for the client to use it accordingly. if start is -1 then it will automatically shift to beginning of the file i.e. 0, similarly if finish is kept at -1 it automatically shifts to the end of the file. Sometimes you wish to search for a pattern like " 68 ?? ?? ?? 00 74 ?? 83" where ?? actually means you dont care what is there in those areas. So how to search in those scenarios? First replace the ?? with a byte you dont have in your original pattern. For e.g. " 68 AA AA AA 00 74 AA 83" and call exe.find() with useWildCard as true and wildCard as "xAA" like shown below. var offset = exe.find(" 68 AA AA AA 00 74 AA 83", PTYPE_HEX, true, "xAA") - i didnt set the start and finish since i want the full client searched. If a match is not found then this function returns -1. ii) exe.findAll(pattern, type, useWildCard = false, wildCard = "xAB", start = -1, finish = -1) Same functionality as exe.find except that exe.find() stops at the first matched location but this one returns array of all matched locations. If no matches are found returned array is empty. iii)exe.findCode( pattern, type = PTYPE_HEX, useWildCard = false, wildCard = "xAB") - Extended version of exe.find() function with searching limited to CODE section iv) exe.findCodes(pattern, type = PTYPE_HEX, useWildCard = false, wildCard = "xAB") Extended version of exe.findAll() function with searching limited to CODE section v) exe.findString(pattern, rtype = RVA, prefixZero = true) - Extended version of find function with searching limited to DATA section. pattern can only be a PTYPE_STRING. rtype argument here refers to what type of address should be returned when found (RAW or RVA). If you want to search for isolated strings (i.e. NULL on both sides) set prefixZero to true vi) exe.findFunction(pattern, type = PTYPE_STRING, isString = true) - Extended version of find function for getting the address of an imported function. You can either specify the function's original name or the address of the function name in IMPORT section. vii)exe.findZeros(zsize) - Extended version of find function used for locating empty space in DIFF section for inserting new code. The function always looks for zsize+2 null bytes to make sure each inserted code is seperated by atleast 1 null byte. 3.3) - Modifying data i) exe.replace(offset, code, type = PTYPE_STRING) The core function used for replacing bytes in the client file. code is the pattern which will replace the original - don't forget to mention the pattern type. There is no return value for replace functions. You can also provide the variable name you used in exe.getUserInput() function earlier as the code (NEMO will pick up the value inside). ii) exe.replaceWord(offset, code) - Extended version of exe.replace(). Here code is expected to be a 16 bit signed number. iii)exe.replaceDWord(offset, code) - Extended version of exe.replace(). Here code is expected to be a 32 bit signed number. iv) exe.insert(offset, allocSize, code, type = PTYPE_STRING) - Extended version of exe.replace() used for Inserting code into Null areas. offset should be the value you got from exe.findZeros(allocSize). 3.4) - User Interaction i) exe.getUserInput(varname, valtype, title, prompt, value, min=0, max=2147483647) - Prompts the user for a value. Based on the valtype you get different windows for value entry and the value selected by the user is also returned by the function. varname used should be unique across patches and can be used in replace & insert functions to refer to the user entered value. title is the text displayed on the input window title bar prompt is the text displayed as prompt next to the input box. in case there is no input box. for e.g. like in XTYPE_COLOR , the prompt is suffixed to the title bar itself. value is the initial value to use for the input. If the variable was set previously or reloaded from a profile/from a previous applied patch, this value is ignored. 3.5) Section information All the four functions mentioned below gets 1 information of a section specified by key. key can be either the section name or section type (mentioned at top) i) exe.getROffset(key) - Real Offset ii) exe.getRSize(key) - Real Size iii)exe.getVOffset(key) - Virtual Offset iv) exe.getVSize(key) - Virtual Size 3.6) Miscellaneous i) exe.getClientDate() - Need i say more? ii) exe.isThemida() - return true if its a 2013 unpacked client. iii)exe.Raw2Rva(rawaddr) - Converts a RAW/real address to Relative Virtual Address. iv) exe.Rva2Raw(rvaaddr) - inverse of above. In case you are still wondering: RAW address is the physical offset of a code (bytes) from beginning of the client which you see in a Hex Editor such as HxD. Relative Virtual Address or RVA is the address you see for the same code when you open the client in a debugger such as Ollydbg. RVA is relative to a value called imagebase hence the name Relative Virtual Address. RVA - imagebase = VA. 4) Utility Functions There are a few utility functions written in QtScript (you will find them in the core folder) to facilitate some commonly done routines. i) "string".replaceAt(i, newstring) - by default strings have a replace command but no command to replace at a specific offset this one does that. For e.g. "abracadabra".replaceAt(4,"k") will return "abrakadabra" ii) "string".repeat(i) - returns new string with the "string" repeated i times e.g. "na".repeat(4) will return "nananana" .... ... batman? iii)"hexstring".hexlength() - returns the number of bytes in the hex string (PTYPE_HEX). For e.g. " 90 49 54".hexlength() returns 3 iv) "string".toHex() - converts string to hex string (from PTYPE_STRING to PTYPE_HEX) e.g. "AM".toHex() returns " v) "string".toHexUC() - converts string to hex string (similar to above but extra null byte padding is provided - like ASCII in Unicode) vi) "hexstring".toAscii() - reverse of iv) vii) (Number).packToHex(size) - packs a number to its little endian hex string with the size number of bytes used up size can be maximum 4. the number or expression needs to be in a bracket or a variable. e.g. (123456).packToHex(4) => " 40 E2 01 00" viii) getInputFile(f, varname, title, prompt, fpath) - repeatedly loops until a valid file is specified as input or the form is cancelled => patch should be disabled. 5) TextFile class Since I found no suitable types in QtScript for accessing files. I have added a new class called TextFile for accessing textfiles.To use the class first we need to make an object of the class (yes i mean in the patch file itself) var fp = new TextFile(); Methods i) fp.open(<absolute file path>, <mode>) - once fp is assigned we need to use the open method to use it to access a file. mode can be "r" or "w" ii) fp.readline() - currently only reading full line is available, since i needed full lines at a time. iii)fp.write(data) - writes the specified data onto file. iv) fp.writeline(data) - same as above but also adds a carriage return + form feed (goes to new line) v) fp.eof() - true when end of the file has been reached. vi) fp.close() - closes the file opened by fp.open() You can check the TranslateClient.qs file in patches folder for an example of its use. --------------------------------------------------------------------------------------------------------------------------------------------------------- Hmm what else .... so now that you have gone through this guide, hopefully you can better understand what is written in the patches already there. and maybe bring in your own ideas? Let me know if any part of this guide didn't make sense, needs elaborations, clarifications etc. FYI: I know it doesn't look pretty right now. But this was done in a hurry since I will be gone for a week . I will clean things up later on.

Working around in MySQL console for database ragnarok. This tutorial is mainly to support the release of pre-compiled Hercules for Win32 by me, OnNplay. Never-the-less it also closer to linux command line instead of using phpMyAdmin, HeidiSQL, Navicat, MySQL Workbench and other MySQL GUI client program. Hopefully, you will getting more confident to use PuTTY when you subscribe service such as VPS or dedicated server. Lets do our first mysql database "ragnarok" and also our first mysql user "ragnarok". To state the command I used quote character "command here;". Please ignore it when you type or select and copy. 1. Download, install WAMP Server and start it. On desktop taskbar near the clock, click WAMPSERVER - server Online > MySQL > MySQL console . 2. Now active MySQL console window is open asking you to "Enter password:". By default WAMP Server logging into MySQL console as "root" and no password. So just press Enter. Now you in the MySQL service enviroment. You should see "Welcome" followed by some texts ending with line "mysql>". 3. You need to change your user "root" password. Type "use mysql;" and you should see "Database changed". Command "UPDATE user SET password=PASSWORD('newpassword') WHERE user='root';". Type "update user set password=password('w4mps3rv3r') where user='root';" and press Enter. The "newpassword" is at your own wish. After pressing Enter, you should see "Query OK," followed by some texts ending with line "mysql>". 4. For the change to take effect on MySQL service, you need to type "flush privileges;" and press Enter. 5. Now you should test the new root's password. Type "quit;" and press Enter. MySQL console window will close. Do step no.1. Enter your new root's password and press Enter. After the line of "mysql>" appear, MySQL service enviroment is ready to execute mysql's commands. When you type a wrong or incomplete command, console will response with "->". What you need to do is just type ";" and press Enter. 6. Now you going to create a database to be used by Hercules emulator. By default Hercules will connecting to IP "127.0.0.1" port "3306" on database "ragnarok". Command "CREATE DATABASE database-name;". For deleting database, command "DROP DATABASE database-name;". Type "use mysql;" and press Enter. Next type "create database ragnarok;" and press Enter. Check the existence of your database, type "use mysql; show databases;" and press Enter. 7. Now you going to create one mysql user for Hercules to use. Do not let Hercules to use user "root". By default Hercules used mysql user "ragnarok" and it's password also "ragnarok". Command "CREATE USER 'user-name'@'host-name/IP' IDENTIFIED BY 'password';".For deleting user, command "DROP USER user-name;". Now type "create user 'ragnarok'@'localhost' identified by 'ragnarok';" and press Enter. Next you should do step no.4. To check the existence of user "ragnarok", type "use mysql; select user from mysql.user;" and press Enter. 8. You already create database "ragnarok" and user "ragnarok" in MySQL service. MySQL user can't simply access database without permission. Now you as a user "root" need to allow user "ragnarok" to access database "ragnarok". Command "GRANT ALL PRIVILEGES ON database-name.table-name TO 'user-name'@'host-name/IP';".For removing user to acces any database, command "REVOKE ALL PRIVILEGES ON *.* FROM 'user-name'@'host-name/IP';". Now type "grant all privileges on ragnarok.* to 'ragnarok'@'localhost';" and press Enter. Next you should do step no.4. 9. You should test the user "ragnarok". Type "quit;" and press Enter. MySQL console window will close. Now open folder where WAMP Server is installed and find where is file "mysql.exe" is located. During the making of this tutorial "mysql.exe" appear as "mysql" is located in "C:wampbinmysqlmysql5.6.12bin". Do not select any file inside the folder, if any one of the files is selected clear the select by clicking area after column "Size". Point arrow inside the folder, hold down the Shift key and at the same time do a right-click. Click "Open command window here". Type "mysql -uragnarok -p" and press Enter. You should see "Enter password:". Now type "ragnarok" and press Enter. 10. Here you going to prepare a text file for later use. Find and open folder "sql-files" which come with Hercules package. All the required files are with an extension ".sql" and can be read using Notepad++. Don't waste your time now to read it. Those files are containing default tables for database preparation. To get the full path of each file is by hold down the Shift key and do a right-click on the file, click "Copy as path". Next paste it in Notepad or Notepad++. Alternatively you also able to select all files and "Copy as path" too. The full path will come with quote character " " at beginning and ending. Delete it. Before file full path, add "source " with one space after it. Prepare file full path line by line so it easy for you to select and copy. Maybe you named the text file as "hercules-source-sql.txt". Before "C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db_re.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db2.sql""C:UsersOnnplayDesktopHerculestrunksql-filesitem_db.sql""C:UsersOnnplayDesktopHerculestrunksql-filesitem_db_re.sql""C:UsersOnnplayDesktopHerculestrunksql-filesitem_db2.sql""C:UsersOnnplayDesktopHerculestrunksql-filesitem_db2_re.sql""C:UsersOnnplayDesktopHerculestrunksql-fileslogs.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmain.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmob_db.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmob_db_re.sql""C:UsersOnnplayDesktopHerculestrunksql-filesmob_db2.sql" After source C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db_re.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmob_skill_db2.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesitem_db.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesitem_db_re.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesitem_db2.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesitem_db2_re.sqlsource C:UsersOnnplayDesktopHerculestrunksql-fileslogs.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmain.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmob_db.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmob_db_re.sqlsource C:UsersOnnplayDesktopHerculestrunksql-filesmob_db2.sql 11. Now you going to fill up database "ragnarok" with default tables. Back to step no.9 and file "hercules-source-sql.txt" opened for select and copy. Type "use ragnarok;" and press Enter. You should see "Database changed". Next inside the console, copy and paste "source C:UsersOnnplayDesktopHerculestrunksql-filesitem_db.sql" and press Enter. You should see many "Query OK," running till "mysql>" appear again. Repeat with other full path of your sql files. After filling up database "ragnarok", you may check how many tables are created. Type "show tables;" and press Enter. Total row is a total table in database. During the making of this tutorial, Hercules is at Revision 12214 supplied with 12 sql files producing total of 52 tables. 12. If you follow correctly this tutorial, Hercules emulator can run smoothly by now. Type "quit;" and press Enter to close the MySQL console.

Hercules on Amazon EC2 (Windows Server 2012) Instance Video https://vimeo.com/68667751 Benefits Main benefits of using Amazon’s Elastic Compute Cloud (EC2) are: Cost You can start with a micro instance which has 750 hours per month of Linux and Windows instance use, along with 613 MB of RAM, 32 bit or 63 bit systems. Which is free of charge with certain operating systems, including Windows Server 2012 Base. This is called the Free Tier. Beyond the free tier you start $0.060 USD cents per hour for a Small Linux instance, which is $1.44 USD per day, or $0.091 USD cents per hour for a Small Windows instance, which is $2.18 USD per day. Not bad at all. Lots of VPS hosts charge this and more already. Just pay as you go. Small instances support 32/64 bits, 1 core, 1 ECU, 1.7 GiB, 1x160 GB Source: http://aws.amazon.com/ec2/pricing/ Source: http://aws.amazon.com/ec2/instance-types/ Scalability Once your server needs more RAM and CPU power than the Free Tier can offer, you can just 1) take a Snapshot of your current instance, 2) Detach your Elastic IP from your old instance, 3) Create a new, more powerful instance from the Snapshot, 4) Attach your Elastic IP to your new instance, and BAM, you’ve got the exact same Hercules server on better hardware. All this in a few minutes. You have complete control. Reliability Amazon’s Elastic Compute Cloud is exactly that. A reliable, elastic computing cloud. All your virtual machines are hosted on the most stable clusters that use the most speedy network connections available. You’ll definitely get peace of mind that you’ll server won’t just stop working one day because of unreliable hardware, software or bad maintenance. Important Creating and using an Elastic IP is FREE of cost. But using additional Elastic IP’s cost you $0.005 USD cents per hour. Which is $.12 USD cents per day. http://aws.amazon.com/ec2/pricing/#elastic-ip Inbound and Outbound Bandwidth per GB is free. http://aws.amazon.com/ec2/pricing/#DataTransfer Snapshots are pretty cheap too. Cost depends on country. You can get an idea of how much your new instance will cost with the calculator http://calculator.s3.amazonaws.com/calc5.html Note: Remember, Micro instances are FREE with certain Operating Systems.
