Panel in Red on Black

Post by Martin A » 31 Oct 2015 19:38

Over on Facebook, Thomas Koch has posted some amazing renderings of the FDX.

For artistic purposes he's changed the colour of the Display used by Panel to red on black. It looks great, so I thought I'd try it out for real.

While creating a new mask rom isn't going to happen, changing the colour on Memu isn't that hard.

The relevant section of the ROM is:

Code: Select all

3813                        .vdpan
3813        21 75 38        LD   HL,sc0pan
3816        06 FD           LD   B,&FD
3818        18 05           JR   vdbas2
The B register holds the screen colour

For red on black screens in Panel change Offset 1816 in the assem rom with a Hex editor to read 06 61 instead of 06 FD and that's it.
