Hacking How do i decrypt Ren'py png files?

Impossible_Igntiz · Jul 25, 2022

If anyone that's well knowledgeable with Ren'py especially the Nintendo Switch ports of them (mostly done by Gamuzumi) that would be very grateful!

the reason i'm asking is so i can start doing an uncensored mod for those games done by the company with it's highly encrypted files...

for example here's how it looks:

Any software you guys recommend to view the .png or a way to re-encrypt the visible ones from the original PC files?

Ren'Py uses unencrypted PNG. If they are encrypted it means that there is modified engine use. You need to re engine and find encryption scheme.

I already found a way, just replace the pngs from the PC version and it automatically reads it, now my new problem is how to make the .rpyc files from the PC version readable for the Switch ports...

but that doesn't matter anymore as i found a new game (from a different company) that also uses Ren'Py for it's engine for their russian Visual Novel games except this one is structured different and is very easy to replace whatever game you want and the game will automatically load up that one instead similar to how Cotton Saturn Tribute engine works.

Hi did you ever figure out how to mod Gamuzumi games? I was trying to reverse engineer the uncensor mod for Sakura Dungeon. But no matter what I do, I couldn't get the mod to work. I could replace png files but none of the rpyc files from pc would work.
