Hi,
I have a Commodore PC-1, which I have upgraded to 640k of RAM.
Some games that I’ve tried to run, and I *presumed* should run on the machine (like Arkanoid, Prince of Persia etc) complain that they cannot detect CGA hardware and refuse to run. Arkanoid II complains that it can’t detect any of the graphic adapter options (CGA, Hercules), but it lets you manually pick it anyway - and the game runs in CGA. Also Planet X3 works in CGA (and of course in the special Plantronics mode, which is cool!), and for example AlleyCat so I believe the machine should indeed have a working CGA graphics adapter.
There was one comment in YouTube (RetroSpector78's repair of the PC1) that says: "To run a lot of CGA games we had to run a small TSR program and then the CGA games would run fine. I don't remember the name of it but it was part of the disks you got with the machine”. Does this sound familiar to anybody, what might this program might have been?
I have set the DIP switches to 80 column, colour, CGA mode. I am running MS-DOS 3.20 (nothing special or graphics related in autoexec.bat or config.sys, should there be?), and CheckIT identifies the video adapter as CGA (at B800h, 16K of video RAM). I am using a Monotech EternalCRT with a modern VGA display.
