I have googled the net extensively and no one has a list posted. I would start to start a list of fellow geeks out there who have tested this emulator so we know what is playable with out having to waste time.
I just got it and have tested a handful of games. I went by the rc to determine what games to get.
Sonic Wings 2 - Works with minor lag and sound glitches
Sonic Wings 3 - does not show in list
King of Fighters 99 - does not show in list
Blazing Star - Works almost perfect
SVC Chaos Plus - does not show in list
Shock Troopers - does not show in list
I don't understand why a majority of these games simply don't show up on the list. I have the proper rcs in the folder, but they don't display and if not selectable, can't be tested.
When running of a cartrige, there isn't a need to load the whole thing into RAM. Its part of the reason why even modern systems have trouble running Neo Geo emulators. I was wondering the same thing about using the SD as a page or mounted extra RAM. Should be possible, but I haven't heard of too many people trying it. Many roms that wont work in GXGEO can be run as CD from NEOCD-WII. Ill test some roms and post it here.
