SM 3.6 + DVD + ROMs

Does uLaunchELF support DVDs if I load it from a DVD SM 3.6 (so there's a DVD TOC)?

If not, is there any way to put multiple emus on one DVD, since more emus support exiting back to uLaunchELF/BOOT.ELF?

Also, which emus support and don't support going back to the menu?

Thanks.

Actually, doing it on CD would be fine if there's no way to make DVD, I don't have many ROMS anyway.

I wanted to make a 2600+GBC+MAME+PGEN+SNES CD (or DVD if it's supported, I'm low on CDs, hence me wanting to put multiple emus on one CD), but am not sure which emus support exiting back to a main menu...

Also is there a mame compatibility list? Some require a NEOGEO Bios, and other sites don't tell you whether or not a BIOS is needed. I've been sticking with small ROMs, but some are unpredictable (i.e. one version of Cruisin USA... which probably is too advanced to play on a PS2... is small, and another is like 4 times the size)...

Others are multi-part... do I need all the parts, and if so, do I need to uncompress and put all the parts back in one zip so MAME can find them?

to be honest i dont like SM that much, nor does my gf, but am willing to try anything.

we rather watch movies using SMS made by EEUG ;)

Anyone? I'm just gonna nix the emus that don't exit to BOOT.ELF and fill it up with my ROMs from emus that do (and use a CD, since a DVD probably won't work).

Also curious about the MAME/NEOGEO issue, and which ROMs work (also why some ROMs of the same game are like 680KB and another of the same game diff. revision is like 5MB)...

What's about the max zip size MAME can handle, and if I unzip into a seperate folder, how do I know which of the multiple files to load first?
