Hi everyone !
I know this is very specific and tons of work... Just asking by any chance, if you've considering making an FPGA implementation of the Pico-8 fantasy console - or releasing some specs so that someone can do it ? This would make it even closer to real hardware... As FPGA implementation is the closest you can do, that's some kind of hardware low-level implementation.
The most well-known current FPGA plateform - pretty affordable too - is the MiSTer FPGA project. Check it out ! :)
Cheers
