I can't even get the TS-DOS ROM to work properly in VirtualT. Each time I initialize the ROM, it brings up the TS-DOS screen, but when I exit (Shift F5), it just gives me an "Ok" prompt and then won't really do anything. I mean I can type, etc. but there is basically no response except to always give an "Ok" prompt, regardless of what I type in.
Plus within TS-DOS, if I hit F4 (Disk), I get "?BS Error in 10". Perhaps my tsdosnec.hex file has some issue (though each line has a checksum on it)? Or maybe my NEC main ROM has an issue. I'm wondering if maybe the DOS-ON feature is not properly preserving the RAM bank number when switching the ROM bank to the OptROM. Both of these bank numbers are set using the same OUT A1h opcode.
