Modified Renewal database for pre-renewal server

[acermedicos 0]

My server (local) is running with Renewal formula as of the moment.
I am planning to switch to Pre-renewal environment.
But I want to implement Renewal items/ maps/ monsters and I only wish to have the following
1. Pre-Renewal Damage formula and mechanics with (99/70 max level , instacast at 150, prerenewal damage calculations)

2. Able to Use Renewal items map and monsters

 

I understand that item_db of re vs pre_re do not match especially in the def and mdef part, same with mob.
I just wanna ask if anybody has open sourced their modified renewal database that fits in for pre-re enviroment.
Thank you.
