A CP/M application ROM loader capable to run native MSX games without changes or patches. W.I.P.
By providing a fake MSX BIOS that translate MSX I/O to Nabu I/O and also interpretes the serial keyboard and mouse. Some ROM files can be dumped from MSX and ran directly on Nabu PC like Zanac. Others may have copy protection schemes like most Konami games so a patched version, the same used on original MSX computer rom loaders need to be used.
The MSX BIOS takes the lower 16KB of the memory the other 16K is BASIC and not needed. The ROM file is loaded into the $4000 address up to 32KB ROMs. The fake bios poses as an unexpanded MSX with 16KB RAM in slot 0 and the ROM as it was running from cartridge in slot 1.
