You're welcome. Thank you for doing this project.
So let's see here...
Edit : do you have that sound in game for The Victory screen theme ? I put it as an attachment
It should be this track here...
https://youtu.be/ZW7WLYZbaq0The link you provided doesn't play the track at all oddly enough.
Link you provided for Balrog (Claw) stage is correct.
The Here Comes a new challenger theme -> this is the sound TOCYU_38.ADX but not found on the youtube link so I put the megadrive version instead. If you can find it I can change.
Found it!
https://youtu.be/3P14Q-BMWfYLink you provided for Honda Near KO theme is correct.
Realistically, you wanna make sure EVERY stage theme (Especially the Character Select Vs. track #52) runs indefinately or for as long as possible (if you take into consideration of the games Training mode which plays stage themes out for as long as someone is on it training or people playing other main modes with timer disabled). If this just isn't feasibly possible due to space restrictions, then I would suggest a 396 sec. length for stage music and a 99 sec. Length for Near KO stage music.
If you need to make additional space, there is always audio compression (tho I'm not a fan of this method) or better yet removing tracks that are useless. Track 71 is obsolete since it's the Network Lobby theme (A mode that is no longer functional sadly), Tracks 63, 64, 66 which are part of the games Tournament mode which isn't even available for play in this version of the game. Track 65 which is an unsed Q sound sample. Track 59 which is the Bonus stage's track that aren't available in this version (tho they can be enabled within the games hidden dips witch settings)
Hope this helps.
