I've been working on a bunch of Street Fighter 2 stuff in relation to ROM hacking, and one of the tools I was after was an easier way of editing palettes. I know there's the PALMOD tool, but it doesn't output raw ROM data like I want it to - so I wrote one myself with HTML5 canvas.
If you've ever wanted to play around with SF2 palettes, give it a whirl. I've tested it in Safari and Chrome.
I've been converting across all the colours from ST, but it's taking a little while - I'll get there in the end.
Send me any cool palettes you come up with!
