Thanks, it's just a shame I couldn't get the performance going well enough. But going to keep at it, and see if I can get it to run on a 286..
Awesome, glad to see another entry that's written for DOS :) Out of curiosity, is this running in proper Mode 4h? Or Mode 13h with the CGA colours?
Just a reminder, this needs to be run in DOSBOX. As it's a proper 16bit DOS executable. Please install via https://www.dosbox.com
To be honest, writing it in pure assembly wouldn't be too bad, but it's a lot easier with qbasic or turbo pascal 6/7 in that regards. Still would be 8 or 16bit in the correct video mode.
Out of curiosity, would writing a 16bit DOS game that uses an actual CGA mode be okay?
