Demon Attack on a CoCo 3

Demon Attack cartridge (26-3099) has a small bug when running on a CoCo 3. The Programmer’s credit and version information is drawn using garbage rather than the correct data from the ROM.


This has to do with setting bit 3 of $FF90 causing RAM to appear at $FExx. This does not happen on a CoCo 1 or 2.
