I fear answering to this topic is something akin to resurecting the dead but I wanted to go back to SoulSilver and I tried this romhack again and the patch was sucessfull, I was able to get past the caching tutorial. (I thought I should provide feedback being the one to point out the bug, even 2 years later, ahem)
But now I have a question, is it possible to get the fps back to normal ? I feel like the game is stuttering. It's not gamebreaking or something, and I don't mind to do some hexa editing, so if someone have an idea I would be very grateful.
