All I know is the PS2 3S setup.
Square - LP, Triangle - MP, R1 - HP
X- LK, Circle - MK - R2, HK
Hope this helps.
I know that, but I mean within MAME itself. I’ll be more specific…
Button 1 = ?
Button 2 = ?
Button 3 = ?
Button 4 = ?
Button 5 = ?
Button 6 = ?
Button 7 = ?
Button 8 = ?
What would each of these buttons be in 3S? Like, is button 1 - MP, is button 2 MK?
Does that make sense?

Button 1 = LP/Jab
Button 2 = MP/Strong
Button 3 = HP/Fierce
Button 4 = LK/Short
Button 5 = MK/Forward
Button 6 = HK/Roundhouse
That pretty much goes for every SF on MAME.
Hope that answers your question, sorry for the confusion.
