well i just updated my pc-gameboy linking program to support custom port mappings meaning you can use it with a parallel port on an expansion card rather than needing a 20 year old computer and/or rare modern motherboard with legacy ports on it
https://github.com/tzlion/gblinkdx/releases/tag/v0.3
was looking into the same being possible with my GBA multiboot dumping setup...........lol
that one depends on abandoned closed-source program Xboo Communicator to act as the PC client & that doesn't allow you to configure the port so fuck me i guess. i'm already stuck using linux for it because theres no way to get raw port access on 64bit windows without a library which i have no way to make it use
@lion maybe the protocol is simple enough that you could poke a pi pico or something into the parallel port and figure out how its sending data
@mothcompute i guess there are 2 parts to it, the gba multiboot protocol to actually send the rom which i'm sure is documented... and then the 2-way communication with the communicator which yeah maybe i could reverse engineer.... reimplementing all that would be a lot of work however you slice it though
