Perfect Paint

[kolla]

"Powerful painter for Gfx cards" is perhaps a hint? Or do you have a graphics card in your A1200?

EDIT: I tested PfPaint on the MiST...
V2.93 only lets me pick RTG modes, works fine and with 16bit 800x600 and 1024x768 P96 modes.
V1.2 also lets me pick native mode, and starts, but appears to be very buggy and hangs easily.

If you are referring to Indivision AGA mk3, then that is not a graphics card, it is a flicker fixer/scan doubler that just alters the video output of the original AGA chipset.

PerfectPaint wants high colour (15bit, 16bit) or true colour (24bit, 32bit) screen modes, and for that you need RTG, that is the Picasso96 or CyberGraphX software, with supported graphics card hardware.
