[Coco] CoCo and Rasberry Pi ( and Software Rant )

[Bill Pierce]

The problem is programs that copy rom to ram. Those offsets are wiped. Tons of games and graphics software use the rom are for storage. This was normal untill the Coco 3.

As long as the program could work with a hard drive DRIVE 0, it can work with 
this trick. You just adjust the offsets to any virtual drive appears as DRIVE 0.

Default:  0-255 drives.

CoCoMax is installed on DRIVE 42.

POKE offsets so RGB-DOS thinks the first drive is located where DRIVE 42 is.

DIR 0 -- now shows the contents of what was DRIVE 42 :)

But, programs that would not work under RGB-DOS still will not work.
