Alec: Hope no problem!

This was actually an older idea, but seeing how people would like to have a good 80 character wide mode, I made an attempt at it on this weekend. It looks pretty good even on my small NTSC composite display, I purposely designed it so the characters should avoid producing color artifacting (tiles are 17 cycles wide especially for this reason).
Partly it is a "normal" code tile mode which would be capable to do colour like Mode 9, however as an initial, probably most generally useful attempt, I recreated an IBM 437 codepage on it. What is particularly new is that this mode has no actual pixels, the display essentially is some 1400 "pixels" wide (AVR cycles). The generator essentially compiles a tileset for this mode while optimizing it (which results in that this full IBM 437 character set takes "only" 20 kilobytes of ROM space).
The code as it is now is available on my fork for experimenting (It is a mess for now, the mode definitely needs more work, however the example should compile fine):
