It's the emulator (lr-retro8). Masters of the Universe is already reported as non-working and I guess other games may have the same issues (either loading or during emulation).

Best to use the official Pico8 simulator and configure it in EmulationStation to launch the games with it (see this topic for an example configuration).

@cdaters Hmm, hitting Start does nothing for me.

@retropieuser555 said in PICO-8: Retroarch lr-retro8 core installation script:

@benmclean Oh really that sounds nice. What's the setup the new build has for that? I currently use xboxdrv and have ctrl+q mapped to start+select

It's just been added to the options menu in Pico8.

For anyone running into this and having issues for... Not paying attention to details for whatever reason. (ADD in my case)

1: ES_SYSTEMS.CFG was not in the opt folder for me, but it is recommended to have it there anyway for alterations, so make a copy of it there.

sudo cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation/es_systems.cfg

2: the <pi> in the code above is the user name/folder. in my case, the folder is called "retropie" - maybe because it's a custom installation. I needed to change things as follows:

<system> <name>pico8</name> <fullname>PICO-8</fullname> <path>/home/retropie/pico-8</path> <extension>.sh .p8 .png .SH .P8 .PNG</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/home/retropie/pico-8/pico8_dyn -run %ROM%"</command> <platform>pico8</platform> <theme>pico8</theme> </system>

I also was not able to install wiringpi, but the gamepad worked anyway. I wasn't able to exit it via gamepad yet, but I've been very away from retropie, so I might just be missing something. (also I was using a gamepad/mini keyboard combo, so it wasn't an issue yet.)

Going to write up a 2001 version of that tutorial.

Power up the flux capacitor, doc !

This is still somewhat confusing as it has you editing files that may not even exist and aren't accessible by the default samba shares. Also, leaving out that chmod step was very bad. I may need to write my own better guide if nobody else has made a simple one.

Anyway, I did this over ssh to make es_systems.cfg accessible so I could open it in Notepad++ on Windows

sudo cp /etc/emulationstation/es_systems.cfg /opt/retropie/configs/all/emulationstation/

I also had to do

sudo chmod -R 0777 /opt/retropie/configs/all/emulationstation/es_systems.cfg

in order to allow me to edit it. This is not easy stuff for dum-dums. It needs a script really. People who just want to play Pico-8 games cannot understand all this arcane wizardry.

Also had to switch to using pico8_dyn

I shouldn't have to choose between running the pico8 cartridge directly versus running splore. I should be able to do either one, anytime. How do I fix this?

(later edit) More recent guide here: https://retropie.org.uk/forum/topic/30736/how-to-install-pico-8-on-a-raspberry-pi-3-or-4-for-dummies-2021-version?_=1627524066426

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

by emulator you mean the linux version of pico8 right?
where do I copy it?

edit: also there is no es_systems.cfg tried doing a search on my pi on both network and by editing it with nano on the pi itself.
