Hi. Sorry to hear that. I have no experience regarding Raspberry Pi - the linux build is a stand-alone build that needs SDL (and other dependencies). Maybe there is a dependency missing? Can you run the PICO-8 tool in general on your device?
Yes
I have sent you the p8 cartridge for the DX version (to your email) - you can load and run this via the pico-8 tool. Enjoy! And Happy New Year! :DDD
