wbml is not working for me, but wbmlb.zip is working just fine under Core D. Kind of silly how MAME non-merged sets work sometimes. The Parent rom isn't working but the bootleg rom is. I've been MAME'n for 20 years so nothing surprises me anymore.
Tried your games and I can confirm all your tests. For Bubble Bobble I was using the wrong rom.Core A:
Galaga 88, Pac-Land and Vs. Super Mario Bros. work
Ninja Baseball Batman boots, but it is slow, and is very prone to glitching
Core B:
Bubble Bobble works
Bubble Bobble 2 and Bubble Symphony are slow, but if you set frameskip to 3 (I think) it halves the framerate but it allows you to play them at full speed
Core D:
Altered Beast works (doesn't work in the alt core), Rygar works
Core E:
Gradius 3 works
Fantastic Journey doesn't work
Not a big list, but those are the games that I play that are missing from the list
It's true, thank you. During my tests they all crashed on core C2, now they all work! Mame mysteries!What would be the point of core I anyway? All of its games seem to work in C2, so it seems kinda redundant to include it.
mario.zip is not working on core A
Is there a direct link you have?
