I just want to point out that in many cases you can't simply chop the ROMs up into smaller parts and then dissamble the code to load it in different sections. You really need to rearrange tiles in the single ROM (if needed), then chop it up then change code in ROM and tile offsets. Also you don't really want to chop it into sizes what simply fit, you more need to take tiles for one level BG in one file, 2nd Level in another. Same goes for characters, one file per character. It is a really big job and certinally harder than converting a game the opposite way around (from CD to ROM format).

Completely agree with Razoola on this one. Small games like Gururin or Puzzle de Pon are way easy to port, but games like Eightman or Neo Mr.Do! can be done but you have to chop down the PCM.
If we wanted to have all the PCM, we need to chop the PCM to smaller size and change codes in the Z80 driver, and since i don't have any knowlegde of Z80 & 68K programming, i can't do it.
Were it get bitching are bigger games, like Nightmare in the Dark or Neo Bomberman. I tried ported both these games and because of limits, both have lost sounds and graphics issues. NITD works but have almost no sounds (and when the Z80 driver doesn't finf the sound or music, you get a very loud beeps in a real NGDC) and as for Neo Bomberman, it's unplayable since there's missing to much graphics. So bigger games means bigger headache to recode the PRG, Z80, PCM and SPR.
BTW Razoola, will you ever release a version of the Unibios for the Neo-GeoCD system ? I'm dying to get one...AARRGGHH!! Ifyou need a beta tester, i'm offering myself since i do have an eprom burner and eraser. Modifying hardware is easier than to modifying software (well...in my case...LOL!!)
