There's pretty good emulation of the neogeo and neogeo CD using the emulators for DC created by chui. The bottleneck with running large filesize neogeo AES games such as KOF 2003 or SNK vs Capcom Chaos is of course that the DC doesn't have enough memory to store the entire rom in its ram, or a HDD to use as a pagefile. I believe Chui's emulator allows for swapping pieces of the roms in and out of ram, such that those large roms could be loaded and even played on the DC, albeit with frequent gamebreaking slowdown as chunks of data are read from the disc and swapped in and out of the DC's small amount of ram. I'm wondering if the major part of the slowdown here is the speed of the gdrom drive as it searches for and transfers data from a cd in real time - and whether the recent slate of gdrom emulating devices such as GDemu make this end of the data searching and loading process much faster such that these large neogeo games run a little smoother. Has anyone experimented with this?
