Installing the PICO-8?

SpudsMcToole

@ellohir Cheers for that. Any chance you can post what you ended up with? I'm a professional writer, I'd be happy to knock up a proper legible tutorial for other folk.

Made some progress. Deleted EMULATORS.CFG and executed the two sudo instructions, now the Pico-8 boots up to this.

(A message also flashed up about not being able to open the path /dev/dri.)

If I type SPLORE the Pico-8 menu comes up, so something's basically working but I'm none the wiser after that. So many questions :D

Why is the start file producing an error?
What is /dev/dri and why does it matter?
How do I get SPLORE to find my .p8.png files?
Why isn't EmulationStation recognising them when the extension is in ES_SYSTEMS.CFG?

Try using only the last part of the extension - i.e. .p8 and .png only.

@mitu Success! Games now running beautifully, thanks. Have removed the START.SH file to no apparent detriment. Will now cobble up a simple tutorial, but would still like to understand why it's giving me the annoying and untidy error about dev/dri every time first.

(Also, is it possible to map any Pico-8 commands to the joystick, eg to quit?)

My guess is either an underlying library that's trying to access the DRI subsytem directly (i.e. GPU access) or an empty parameter.

Parameter in what?

Parameter in what?

In the Pico8 emulator command line.

@mitu You mean this?

    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/home/pi/pico-8/pico8 %ROM%"</command>

Doesn't seem to actually HAVE any parameters..

Yes, it doesn't - so that's off the list.

@SpudsMcToole i had the same issue, make the pico8_dyn executable and use this one. No error about dev/dri/ !

runcommand.sh 0 "/home/pi/pico-8/pico8_dyn %ROM% -run"

Good news guys! Looks like there will be a Pico-8 compatible core coming soon!
