Hi everyone, I'm new to the site.

Can someone please help me with an emulator? I'm trying to play the game Chaos Heat, but it won't work with the MAME emulators I've downloaded. Not sure what I'm doing wrong.

I'm also trying to play Last Resort, Gradius III, and Gradius IV arcade for MAME. (Of course these don't work, either.)

Chaos Heat I really want to play, so if someone can at least help me with that, that would be awesome.

Thank you!
