Looking to achieve RGB analog video out on a Neo Geo Pocket Color. No known mods currently exist for this. There are single digit K2_VIDEOs out in the wild that achieve this, but I believe these were made by SNK themselves for internal use only. Other people have apparently gotten video out with FPGAs, but no one has publicly documented it.
Here are the LCD signals as printed on the board & additional information from someone who's apparently achieved this:
I've done it with a small FPGA. The LCD signals can't be simpler: R0~3 is 4bit red, G0~3 is 4bit green, B0~3 is 4bit blue, DOTCLK is the pixel clock, SPL is horizontal sync, SPS is frame sync.
It can't be done by just wiring a scart cable to the board, you have to buffer and convert the color data from the NGPC, then do digital to analog conversion if you want analog RGB output.
I'm venturing into the FPGA scene for this with no past experience with FPGAs and a rudimentary understanding of digital electronics (I can follow guides, solder, etc. I built a CMVS this way).
Any help would be appreciated. Thanks!
