Hi, great work porting this, playing on FBneo RC4.
shun goku satsu has knockdown, usually opponent lay solid on the floor rather than getting knocked down after the screen flash. this applies on both Akuma and Evil Ryu.
demo intro show Ryu should be j.mk cr.mk and fireball to Chun Li.
Vs. screen very faint sound effects (modern)
Is there any plans on changing commands for Akuma, evil Ryu red fireballs to HCB+punch and Dhalsim's yoga flame.
Evil Ryu's red fireball has multiple hits like Akuma's
Zangief's green hand isn't DP motion
Violent Ken's dash move DP motion feels too tight on timing.
some of these are just suggestions I'm not sure how u want the game close to the switch version or arcade.
