I'm probably going to kick myself when somebody gives me an obvious answer ...
Is there a way to insert code (a ROM extension) into the memory map at startup? In particular, I'd like to have a PCjr cartridge resident during the emulation but I don't want to use the BOOT option to get it. My emulated machine should think it is running DOS and just have the code resident in the memory map.
Real PC DOS has a way to scan for cartridges and recognize if they have embedded runnable BASIC programs or executables in them. I'm not too concerned if that doesn't work - I can hack up a cheap jump that works once to get to the code. (I think ...)
In this particular case I know of somebody trying to run PCjr Colorpaint, but they are using the BOOT option and Colorpaint is probably figuring out that DOS is not available. When that happens the FILE menu in the application is disabled. Running it normally through the DOS prompt would cure that glitch.
Thanks in advance,
Mike
