Well I honestly hadn't originally planned for a SNES9x save editor, but I'll definitely have to do some revision now.
I'll take some time to focus on it now, and I'll keep updates on my site as well as this thread.
Update:It seems SNES9x saves are kind of a pain, which is why I didn't choose to work with them to begin with. They're compressed with gzip and have a special header. More than likely if I do anything it'll eventually be a SNES9x <-> ZSNES savestate converter.
Char's that have met Chrono's Mom and Spekkio's current form should be easily altered, I'll look into finding the values once I get done the giant mass of other features I need to add.
