That's the first rom I tried from: https://atarigamer.com/pages/celebrating-atari-lynx-30th-birthday. It loads these 3 pics and then just goes black and nothing. I just tried it again and same result. I have no idea why it's happening, but it is???
I just downloaded rj1307's v2 from a couple comments above - which is the better updated rom and it works fine. I don't know if it has anything to do with I have one of the first LynxSD carts??? All I know is, it's a fun game.
