A1200 cfcard problem or rgb cable?

If you suspect incompatibility with a new piece of hardware, try removing said piece of hardware and see if problem goes away. Troubleshooting 101.  Also check cables, metal RF shield over motherboard, yadda yadda.

Correct.  2MB is not enough to play most WHDLoad games, since just loading the operating system consumes a bunch of that.  I suppose some old 512K A500-era games might work.  Try turning off (PRELOAD) option in the icon settings, as well.  Makes the game slower, but might help with memory.  Better once you add some fast memory to the system.
