New Pico-8 System on EmulationStation

[ellohir]

Hi everyone, I love Pico-8 and I decided to integrate it into Retropie. I followed the (somewhat old but still working) guide at https://www.lexaloffle.com/bbs/?tid=3935

I added pico-8 to /etc/emulationstation/es_systems.cfg

<system>
    <name>pico8</name>
    <fullname>PICO-8</fullname>
    <path>/home/pi/RetroPie/roms/pico8</path>
    <extension>.p8 .p8.png .sh .png</extension>
    <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 "/home/pi/pico-8/pico8 %ROM%"</command>
    <platform>pico8</platform>
    <theme>pico8</theme>
  </system>

I downloaded some games (I already have the pico-8 binary working on the ports menu but it requires internet to browse the games) and left them on the roms path. It didn't find any games (looked it up on /home/pi/.emulationstation/es_log.txt and there was no problem with the system, only said "found no games").

As all my games were .p8.png I added .sh .png to the extension list (as shown above) and made a .sh file and an empty .p8 file. I set it up so all files have 644 permissions.

pi@retropie:~/.emulationstation $ ls -l /home/pi/RetroPie/roms/pico8
total 356
-rw-r--r-- 1 pi pi 32224 Nov 27 10:28 Across_the_river.p8.png
-rw-r--r-- 1 pi pi 23958 Nov 27 10:28 Combo_Pool.p8.png

-rw-r--r-- 1 pi pi 45104 Nov 27 10:28 The_Wee_Dungeon.p8.png
-rw-r--r-- 1 pi pi 29046 Nov 27 10:28 U-Turn.p8.png

I restarted EmulationStation and only the empty file was there:

pi@retropie:~/.emulationstation $ cat /home/pi/.emulationstation/gamelists/pico8/gamelist.xml
<?xml version="1.0"?>
<gameList>
        <game>
                <path>./prueba.p8</path>
                <name>prueba</name>
                <playcount>1</playcount>
                <lastplayed>20190413T094923</lastplayed>
        </game>
</gameList>

So I now have the system on Retropie, I can see it with the logo and everything, but when I enter the system only one rom appears and it doesn't work. Could you guys give me a hand? Why are this files not being recognized as roms?

Rename your .p8.png files to .p8 and restart Emulationstation, your files should appear in the gamelist.

@mitu yeah, that's what I'm going to do, thanks!

Still curious about why it only recognises .p8 and not the rest of file extensions...

So in the end I did end up making the gamelist myself. The good thing is that the game and the thumbnail are the same file for Pico-8 games :)
