Bellreisa has been kind enough to host a VSav wiki over at Mizuumi which has been collecting a good amount of information as time goes on. There's still some missing data that has yet to be transcribed, but it's coming along quickly. In the meantime there's GameFAQs for character movelists, and for framedata there's a mirror in Japanese and a mirror translated in English of the shu180sx data site.
Additionally, Felineki over at the RandomSelect forum has discovered the memory addresses for hitboxes in the arcade emulation of the game. Because of that data, MZ over at TASVideos was able to implement a Lua script into their build of Mame-RR and FBA-RR (which was updated by MZ to be able to run Lua scripts) that allowed us to see the hitboxes while playing the game. More information about what the boxes are and where to get the emulators and script can be found: here.
Naturally, I encourage anyone to help transcribe data onto the wiki, as help is appreciated. If you know anything about a particular character, that's cool, but if not then anything would help: move list, frame data, hitbox screen captures, whatever.
In the mean time, please enjoy some videos.
