From your description, I believe your problem has something to do with switch debouncing issue. Google "switch debouncing" if you don't know what I'm talking about. Most likely it's due to a poorly designed hardware or/and poorly written firmware. You might be able to fix it by using a couple of capacitors + diodes.

Good luck.

Sorry I should have been more specific. When I launch it, as per the wiki, I don't get the option to load anything. When I type "CAT" it tells me that there's no disk inserted.

Thanks, I will try it tonight :)

regarding speed - you may want to compare your results with those on the compatibility lists on https://github.com/retropie/retropie-setup/wiki/Managing-ROMs

if you're getting different results from others, maybe it's a different issue. you don't have a shader on? overlays shouldn't affect performance but shaders for sure can!

/tmp/runcommand.log may show some sort of error, after you get a failed load

@Ornitorick putting your es_systems.cfg is still better practise in /home/pi/.emulationstation as any update or new system you install will reset it otherwise. You'll just have to manually keep it in sync as new systems are added or updated

@Rascas thanks, ill give it a shot later tonight.

@herb_fargus

Thanks Herb, but no luck. Have tried it allready, but no effect.

Ok I found a way to do it: I use RomCenter and create a new database. Apart from DAT files for emulators, RomCenter comes with DAT files for specific systems, like CPS1 etc. I add the folder containing all my asorted roms. RomCenter will only show me the (working) roms for the system I set up the database for. I can then select all roms right-click and choose to copy them to a new folder, which is then my clean, sorted folder for that system.

@dankcushions my problem was to select and split roms into different folders for different systems (automatically).

I've been searching, finally found it.

@KyleBriggs not necessarily, but if they are original game files that the engine in the ports section utilises yes.

Its a 3.5 inch TFT from TinyLCD. I am trying to run the program without root I have worked on this for like a full week now with no progress at all. I am thinking of just buying a car backup screen and a converter from hdmi and calling it a day.
If you need anymore info, then you can just ask!

Generally speaking html5 games (or any web-based games for that matter) run like sludge on the pi.

I dont know what electron games are

If you are looking to port it Likelihood it will be a bit of manual work to port as most ports will essentially be starting from scratch. You can go the formal multiplatform route with C++ and SDL etc. or you can look into the love engine which has a pretty decent community for development but the game has to continually be developed to keep up with the love engine versions
