I built the rom and it plays great under RetroArch (Handy core). Totally playable but has its quirks - audio off here and there, weird vertical screen movement since aspect ratio of lynx doesn't 100% line up. But totally playable. I would have loved this back in the 90s on my lynx. And it makes me want to get a rom cart to try it on actual lynx hardware. Im surprised at how accurate a lot of the sounds are compared to a NES.
