There are many critical isues that would benefit from you enabling the Discussions section on this project

Thank you

These are critical issues for writing unit tests for dos

i don't have dosemu natively in subsystem android (I'm in vacation) and need to run my test in dosbox

completely mysterious crashes led me to this

turns out a COMBINATION of protected mode works. one for compiling and another for runtime


dosbox -c "MOUNT c ." -c "c:" -c "fbc a.bas"

dosbox -c "MOUNT c ." -c "c:" -c "hdpmi32 -r" -c "a"

Yellow text in a famous 81 game is absent from the only working TERMINAL emulator text mode emulator terminal.c in dosemu

I have two write unit tests from scratch since it's mostly ad hoc trial and error written

I still don't know if it can handle ANSI text as graphics modes at all or only ANSI mode 0
