Sega Naomi Error 54 on some Games

[Joystick2600]

Lakka OS RPI4 Stable 3.0 build

For Example “Trigger Heart Exelica” and “Under Defeat” gives a Error code 54 which I then fix by changing the Naomi system settings to vertical. But then I’m stuck playing a game in a vertical display that makes it awkard to play.

How do I get around this?

Hi,

I’m not sure you can bypass this for Naomi. However, those games are available on Dreamcast, you can use these versions if it’s ok for you.

I think I saw those those 2 titles available for Dreamcast as well.
