I'll add to the list as I come across more. If anyone's up for a challenge, help me out here. I was able to find the one for Rumble Roses and make a tool if anyone is interested. Well, if anyone actually has Rumble Roses XX and wants to try hex editing it, give this a shot. I included a modded save data file that has over a million money on each of the 12 Roses I had unlocked. Just replace the one in your container with it. Source is also included. I just pieced together some old function libraries from my other projects for it.
Checksum fixes needed:
Dynasty Warriors 6 (original, not Empires)
WWE Smackdown vs Raw 2011
Other: I want to enable the in-game cheats for Clive Barkers Jericho. I can't believe nobody has figured that out.
Rumble Roses XX
edit: Ok, WTF? I looked at Smackdown 2011 and compared 2 saves where I only changed stats in RTWM slightly, but there's nothing else changed. No checksum. Yet, every time I try to edit that same value for the stats, it tells me the save is corrupt. I just thought of something I need to test on this. I've seen a few games that didn't like their saves being moved. I need to make sure I'm trying an edited save with the proper device IDs just in case.
