Yeah, I used the WinRAR setting to zip entire folders into their respective zips (but not zipping the individual folders themselves).
Its just confusing because I used one of my Darksoft ROMs to make Art of Fighting into a zip. Put that in the games/mame folder to test. Game didn't boot, so reading through this thread I saw that it was a neogeo.zip issue - mine was missing unibios.rom. Fixed that up and poof - AOF boots up.
So then I went and mass zipped like I described up there, and I got cross hatches on everything but AOF, which I did not replace, it was still the test one I had from earlier. OK, so the BIOS is loading, but somethings messed up w the ROMs.
So I got the newest rollup pack mentioned here. Same thing. Crosshatches.
So I tried just one game, 3count bout, booted normally.
THEN, I got the ones that were in the Neo folder for the 'console' version. Same exact thing as before. Then I thought, well maybe its the mass zip thats causing it. Dont know how, but maybe? So I tried a few other individual games, and then I started getting audio/graphical glitches. I just made a shoddy little vid of what is going on.
Now, mind you every game I select in this video is from the same set- pulled from the Console version of the Neo ROMs, which were the Darksoft set. The big one to look at is Fatal Fury, it loads fine on the console version, but he zipped version in the MAME folder has that weird graphical glitch.
