No.23890 VasiliyFamiliya Tester Dec 13, 2025, 08:37	The same problem presents in first Rayman, but in this case it's disappears after SoundBlaster 16 joystick axes unboundment out of direction keys. Let's see how this move affects Mega Man X.
No.23891 VasiliyFamiliya Tester Dec 13, 2025, 09:03	Mega Man X also plays normally after that.
No.23921 Kale Developer Dec 15, 2025, 15:09	Set has been softlisted after https://github.com/mamedev/mame/commit/120721db422d9fa842b0b2a64009b4ac155c4cac I'm otherwise not sure about what to do with this bug report. If you tried to install with default "capcom pad" then that's bound to fail given there's no support for that (and definitely doesn't want the canonical analog joy). I don't see any directional issue with keyboard option either.
No.23923 VasiliyFamiliya Tester Dec 16, 2025, 02:33	I chose exactly a keyboard during installation.
No.23997 ICEknight Tester 28 days ago	This is just due to MAME's default PC joystick being analog and how slowly it returns to its default position when mapping it to keys or a D-pad, so not a bug.
