Maybe.
I have FF7 installed on my PC now and have been playing musical save games between my PSX emulator in Linux and the native app on windows. So I can capture from either. I did do the battle mechnics from Terrence's doc. For fun, you can capture a screenshot of all of the 31 statuses (sleep, blind, poison, silence, etc) . I can add that to battle mecanics tables.
Also does any one know when the 7777 check is made during the battle program flow. Terrence didn't mention it.
I'm working on adding all the known file formats right now. It's a bigger project that I thought. Formatting it all is such a pain ^_^
