/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.

also you posted in the wrong area - We have a section for support.

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

@dankcushions Awesome. Thanking you kindly sir!

That error could be related to this:

thanks, successfully compiled it and soul calibur works in versus battle mode (2 players)!
download source from here:
https://github.com/RetroPie/reicast-emulator

just be sure to compile reicast in the /usr/local/bin/reicast directory and first install all the developer buildings before you type and enter "make clean && make":
sudo apt-get install
libasound2
libegl1-mesa-dev
libgles2-mesa-dev
libasound2-dev
mesa-common-dev
libgl1-mesa-dev

in the end you'll get two files in the shell/linux/ directory. you just need the reicast.elf. but rename reicast.elf to reicast (without file-ending) and copy it over to /opt/retropie/emulators/reicast.
but make a backup before you replace the old file.
