The released binaries don't include any roms.
To run the emulator you will need to put roms folder into the same folder as nc2000.exe/nc2000mac.
Change:
Fixed a crash-bug.
Rom Files:
BaiduNetdisk (code: uuf2)
MEGA
(note: the roms were collected from internet. They're shared here only for nostalgia. Don't use for any commerical purpose)
