Hey guys,
Sorry, I've been away, I became involved in a _massive_ project to bring the legendary PLATO timesharing system to vintage microcomputer systems as an on-line destination, to this end, I've set up a system @ http://irata.online/ and I have written OVER A DOZEN TERMINALS FOR DIFFERENT VINTAGE COMPUTING SYSTEMS, all written in C...
...which brings me to here:
I have a working terminal that builds with CC65, it's used to target apple2, atari, c64, and c128 versions of the PLATOTerm software I am developing...
...I'd love to see if I can get a working bitmap mode on the NES that could get 256x192 resolution. If I could do this, I could get somebody to make a bridge to bring a Raspberry PI onto the cartridge bus, and provide the necessary connectivity and keyboard needed to turn the NES into a PLATO terminal.
Why? JUST BECAUSE. I want to port PLATOTerm _EVERYWHERE_ (I plan on over a dozen ports to more systems, this year, alone.)
How could this be done? Could I set up a raster interrupt to split the screen into thirds, and do a method similar to the GRAPHICS II mode for the TMS9918 based systems? (I support a few of those, btw, TI 99/4A, MSX, Coleco ADAM...)
I would really love to see this running on a NES, just because.

p.s. here's a pic of what a 256x192 display could look like, from the ZX Spectrum port:
