every time i run some games on a CDT file in WinAPE, i get this error: "Memory Full in 30". what is this and how can i fix it?
Looks like a CPC specific problem.
I think the game you try to load, was designed for the CPC 464 and you are using the 6128 roms / Plus Cartridge.
Yes, so try CPC464 without any ROMs (except lower ROM and OS)
