Screen 12 in Windows 7 and above

[cgaman]

I want to run QB1.1/4.5 in Screen 12 fullscreen in Windows 7 and above. Is this even possible?

P.S: Screen 0 still works in Win10 for anyone interested.

Only via DOSBox, I'm afraid. Seriously, even on 32bit Windowses that are newer than XP (Vista+) and even on XP to some extent (try running Doom in DOS window in Win98, then try the same in XP, then tell me about performance compared to doing the same in fullscreen dos mode), DOS emulation is awful. You NEED to use DOSBox to play with QuickBasic on these systems.
