Is it possible to export images from a game? Print Screen doesn't work on CUSTOM.
From OHRRPGCE-Wiki
In GAME.EXE you can press F12 to save a screenshot file.
CUSTOM.EXE does not have a built-in screenshot function, nor does it have a feature for exporting graphics.
On some versions of Windows you can take a screenshot by pressing ALT+ENTER and then pressing PrintScreen and then pasting into a graphics program. On other versions of Windows, this does not work.
Alternatively, you can try OHRGfx, a program specifically designed to export graphics from a game.
If this trick does not work for you, try running CUSTOM in DosBox or try the new experimental Windows version of CUSTOM
