Hi, I have an RGB30 with an up-to-date version of Rocknix and the latest RPi (64 bit) version of Pico-8 installed.

Some games run and play just fine, Celeste 2 for example. But some games quit after they've loaded when I try to play them. For example, ExTerra - It loads okay, but when I select 'play' and then 'retro' or 'modern' from the in-game menu, it flashes "loading" briefly on the screen and then quits.

Does anyone have any ideas on what might be happening? Thanks.

I don't own an RGB30 myself so I cant test my theory out myself, but I notice that ExTerra is a multi-cart game. Could it be that you don't have all the carts downloaded for use ?

Interesting thanks, I didn't realise some games are multi-cart. I've checked the ExTerra page though and I can't see any indication that it's multi-cart, how can I tell (and download them)?

Also, some of the games that aren't working used to work, which would lead me to think it can't be a multi-cart issue.
