Garbled display on some MAME games, instant crash on others

[Soup'um]

I downloaded the demo to make sure I could get MAME ROMs running before I invested in the full version. After a bit of messing around, I got a collection of 0.159 ROMs, which work in MAME 0.159 perfectly. I then downloaded the MAME 2014 core, and set up NRA:N with a few games to test them out. Some run just fine, like Bubble Bobble II, and SegaSonic The Hedgehog. Others, however, display a garbled mess, like Ms. Pac Man, and Space Invaders. The game is still clearly responding to input, and the sound is fine, it just can't display it correctly. More advanced games, like Marvel Super Heroes, Metal Slug and Tekken just crash the game instantly. I tried some other cores from Retroarch, and they all crash, even on the good ROMs.

Is there something I've missed? I adjusted screen style from Pixel to HD incase that was causing issues, and console games, like Streets Of Rage 2 work just fine, on a arcade cabinet or on the console. Is there something different with how the demo and full game handle emulation, like MAME version or compatibility?

Thank you for your time.

The glitched display is a known bug with the demo that was later fixed in the full version of New Retro Arcade Neon. The reason the glitch happens in the first place is because some games change their display resolution on the fly.

As for Marvel, Metal Slug and Tekken, it sounds like you might be missing a few ROM files needed for those games to operate. Qsound.zip and neogeo.zip are the BIOS files that are required for CPS2 and Neo Geo games. As for tekken, it won't run in the demo properly because of the previously mentioned resolution issue. It might also be crashing instantly due to a missing ROM file. If you shared the filenames of your crashing ROMs, I'd be happy to look into that for you.

Thanks for the reply. Summer Sale should be coming up soon, so I'll get the game then and see if my ROMs work. As for the other games, I actually completely forgot about the BIOS ROMs, so I'll load those in and see if it still crashes.

Once again, thanks for the reply. I was going a bit crazy trying to figure out the issue.
