So while Aroc was rocking his way to making an editor, I've been trying to figure out how to edit Revelations 2. If you're willing to work on things with your own exploits, there's one solution I've found. Good ol' memory editing. There's a program called NSwitchDebugger which requires you to have a custom kernel to load temporarily, a whole bunch of files, and a game of choice.
Basically search for the value you want, change it after the search takes a while (It seems like it would run on forever, I don't think it does, but it's fairly quick on finding gold in rev2.) and then use "Repeat search" afterwards and it'll be much faster as it's working off your hits from before (Just like Cheat Engine)
So while I regret to say I can't create a way to edit the save (it uses an internal checksum and the steps for replicating the verification are a bit out of my league), I can link you to an editor for memory that should be able to help out some.
http://games24.blog.fc2.com/blog-entry-374.html is the link to the editor. Not sure if allowed to link it, mods, please feel free to remove it or tell me and I'll take it down.
What you do is download the files in the order it tells you (Google Translate does a good enough job that you can kind of get what they mean. Copy them over, RCM smash using the payload it tells you (CTCaer 3.2) - I found it easier to put it with the other kernels and rename it to payload.bin and the old one to original.bin. That way you can just use the batch/bash files for your OS and Architecture.
So far I've been able to successfully change gold, and I'm about to attempt level, then skillpoints. Since nothing else is gained with leveling up, I don't have to worry about "stats". After that, all I have to figure out is how to memory edit in mods I want, or probably start farming.
Thanks for riding along with me, the blog entry is my way of saying "This is the end for Revelations 2", and we have a fancy editor for Revelations 1 thanks to
@Aroc who deserves thanks for making it easy to edit a save. With that, I think I'm done on this thread, but it's more work than I'd seen on the board, so I'm content.
