Here's an updated version with what's available on the patreon, same deal as last time, there's the untouched one and the cracked one Updates for KOPC and SBO are big, there's a few new girls and bug fixes, I'm not gonna give a precise changelogs because it's scattered on a number of posts on Patreon. For the PB series, there's bug fixes for raven and lara, one new nobara costume for C18, one new nico costume for widowmaker, and two for Chun-li : tifanny and momo (the tifanny one did not seem implemented last time, might have been a bug on my end) If I'm not there in the future, cracking those games does not need a lot of technical knowledge, it's just tedious. You have to download a flash de-compiler ( i use JPEXS ), open the files, and use the search option to find the codes ( using "code", "passcode", "patreon", or "this.code" should get you there) : they'll look something like this : F39889EB42412593927C5136480E66F4FF0B813E071F2E5DDAB70C14154692E4 Those are encrypted in sha-256, which basically mean that you can't decrypt them back ( it's a little bit more complicated than that but this isn't a post to explain various encryption algorithms), so what do we do ? We encrypt the words that we want to use with the same algorithm and replace the one in the code with ours. Basically, choose a word or a phrase, put it in https://gutool.com/sha1-calculator/, check the upper case option, click the "SHA-256 HASH CALCULATE" button, copy the line generated, and replace the line in the code with the one we just created : Congrats, you just did what i did.
