Try this build: https://drive.google.com/file/d/189X_SMGxH4N3IijWY5DVfMwH29DoThhS/view?usp=shari... also make sure you have a higher resolution then at least 640x480 (thats the game resolution). Also AHI should be supported in your OS.
I'm sorry to report that build 303 didn't work either... still the same failed to open 640x480x8 custom screen error. Do you have a specific screenmode so that I can add to my system maybe??
