I've seen some interesting NES/Famicom conversions to PC Engine / TG16 in ROM collections. Apparently there are a lot more of them - here's a thread about how they were done: https://www.pcenginefans.com/forum/index.php?topic=23408.15 https://www.pcenginefans.com/forum/index.php?topic=23408.15 Basic idea is that both consoles use 6502-family CPUs, and vaguely similar tile + sprite graphics hardware, so the original machine code can mostly be run while adapting the specific register programming of one machine's graphics/sound hardware to the other - it helps that the target machine is much more capable.
