2 questions from a Miyoo Mini Plus noob - Lemmy.world

Hi, I finally received my Miyoo Mini Plus yesterday, and having already had an Anbernic RG353V found most stuff intuitive / obvious enough - but there’s 2 things I haven’t figured out yet. Firstly, I’m set up with onion OS 4.2 RC on a new SD card (not the one it shipped with) and the tiny best set ROMs for 64GB cards, but whilst every other console is fine, nothing ever shows under Arcade. It says scanning, I see the number counting up, and then a second later it says “empty”. I have the verified Mame 2003 package installed from the package manager, don’t know if anyone has any ideas? Refreshing the ROMs doesn’t make any difference. The second thing is I can see that alternate cores can be downloaded from the package manager, such as Genesis Plus instead of Picodrive, but I can’t see how you would actually select which core to use once downloaded? On my Anbernic, Genesis Plus seemed smoother than Picodrive for Mega Drive/Genesis games… although maybe on the Miyoo Picodrive runs better as it’s the verified default? Thanks!

Great questions, HexagonSun.

Arcade

There are a few things to check here.

  • Your ROMs should be in the Roms\ARCADE folder on the SD card
  • the ROMs should be in the .zip file format
  • the file Emu\ARCADE\config.json should look like the following:
  • { "label": "Arcade", "icon": "/mnt/SDCARD/Icons/Default/arcade.png", "launch": "launch.sh", "rompath": "../../Roms/ARCADE", "imgpath": "../../Roms/ARCADE/Imgs", "gamelist": "../../Roms/ARCADE/miyoogamelist.xml", "useswap": 1, "shortname": 1, "hidebios": 1, "extlist": "zip" }
  • there should be a file in the ARCADE folder called miyoogamelist.xml; this should contain XML entries for every ROM in the folder; the file names in this file should match the ROM files in the ARCADE folder (such as outrun.zip).
  • Cores

    Most of the time, it's better to stick with the default core, but there are a couple of options for choosing a different one.

    Enable the Expert tab (Apps -> Tweaks -> User Interface -> Show expert mode): with Genesis Plus installed, Mega Drive/Genesis games will show up in the Expert section as playable with that core
    use Game List Options (GLO): in the standard game list, bring up GLO by pressing Y, and choose a different core; this will only affect the highlighted game and is useful when there are a few games that don't perform as well with the default core.
