We ship the
Indivision AGA 4000 / CD32 with the latest firmware, but we are working on a CD32 self booting CD which our customers can obtain to reflash the unit with later firmware.
Indivision AGA 4000 / CD32 is fully compatible with NTSC and PAL games.
With the Indivision Config tool, you can turn on/off scanlines, just ask for the CD with Indivisions tools on it at time of ordering.
Hope this helps!
