[Coco] Interbank Incident for Drivewire

[Luis Antoniosi (CoCoDemus)]

looks like it uses 51x32 characters, so there is not much space for
bold characters.

The only way to fix that would be to redo the character set so that the characters are "bolded" (2 pixels width minimum), and aligned to show as white. That is probably too much effort.

If Interbank is using either display graphics commands, or normal bitmapped graphics, then a PMODE 4 style artifacting screen is identically set up to a PMODE 3 style 4 color screen. You would lose "subtle" colors (yellows,etc.), but it should work fairly well. I know I had patched Biosphere the same way many years back, and it worked fine.
