@Drakaen391 Exactly, that is how I always did it. I also use this method to edit the .cfg files.

I looked into this concept some, but had a couple problems. The way that I tried, was a usb device selector in usbromservice.sh that would throw a couple short scripts with the device UUID into /etc/usbmount/mount.d and /etc/usbmount/umount.d/. So any time the usb device with the matching UUID was plugged in it would be mount --bind to the roms directory. It worked alright for vfat, but ntfs gave me problems.

Since it's filesystem stuff, there's a lot of ways to accomplish it. It seems like if it's done in the right way it could be useful. But I think it could potentially cause a lot of problems for users. I also think that a solution with options to not only have sd or usb, but both in emulationstation, would really be the ideal. Another thing to consider is whether or not the scraper will work properly.

One of my thoughts was a script that would generate a modified version(to override, but not overwrite) of es_systems.cfg with the paths changed and potentially the entries duplicated. So you could have the SD card directory for NES and a USB directory for NES both showing up in emulationstation, or one or the other.

And remember to keep the "Parse Gamelists Only" option off. This is the default, if you didn't change, don't worry.

UPDATE: got an alpha level script written... It's very messy but will make a new thread looking for testers once I get a successful run on the pi itself (runs on Ubuntu)

Looked on the old forums and this was my original post:

If you want it to load on the fly, then it won't work at all due to emulationstation...

Better idea would be to use a USB and change it before turning on the Pi

come on now. cemu needs a monster pc. the raspberry pi is basically the worst pc money can buy :)

@BuZz great! Thanks man!

There is a Plus4 emulator already installed.

/opt/retropie/emulators/vice/bin/xplus4

You can add it to the es_systems.cfg as a different system, or just put the roms along side your 64 games and add another line to the emulators.cfg under /opt/retropie/configs/c64/

i.e.

vice-plus4="/opt/retropie/emulators/vice/bin/xplus4 %ROM%"

And when you launch, press a key before it launches and select the emulator for that rom. After you do that once, it's saved for that game.

Later,

You have my vote Sir!

@sc0tt88

is the tutorial I used to get it working. It's in zerojays retropie-extra repository. Still having a few ps3 controller issues with it, but I seem to be one of the few so it should work fine.

Superb !! (installed it from RetroPie-extras)
BTW, where should I specify the resolution it should run in so that it's taken into account by ES ?

This is a big offtopic, but you made my day with this web link, its just what I needed for my old computer references for 3d modeling, awesome!!!! :D

Yes i thought only about legal option where customer will pay for game but of course all depend from prices :)

I will symlink them to the retropie configs area.

@Arcuza yes you are correct, but using other emulator save folder unique for all emulator solve it problems for backup and upload, using /savefiles for all emulator.

@sc0tt88

It's being worked on. You can track most of the progress in this discussion...
