This project embeds CPM+.SYS for the Commodore 128 in a .prg file. This is useful for booting CP/M off a flash cart, such as the Kerberos. Booting CP/M this way will shave off at least 15 seconds of boot time, plus you don't need CPM+.SYS on your boot disk, leaving 24+ KiB of free space to use.
Download the .prg - This version contains CPM+.SYS from this repository
To build your own .prg, replace CPM+.SYS with the version you want and run
