@Concat
in RetroArch you can change the controllers on-the-fly:

Settings -> Input -> Input User N Binds -> User N Device Index

But keep in mind that it can bring some annoying situations, as I described here:

@BuZz Okey Dokey.Quick Install it is!

also please format your posts on this forum - especially console output/logs etc - see https://retropie.org.uk/forum/topic/3/read-this-first

Nevermind, figured it out :D Used jstest /dev/input/js0 and found the numbers.

rpi-update should sort it, or wait till a new kernel is packaged. Controller may still work in xinput mode.

Yeah, it is easier and cleaner than the way you were trying to do.

OK, I figured it out... if anyone is interested. It was a power issue all along. The 1tb SSD apparently uses more power than the 240gb SSD .

It was just a matter of using a usb adapter to power the 1tb SSD... Weird that the 1tb SSD draws more power than the 240... I assumed the power draw difference would be trivial between them. Apparently i was wrong. I have no idea if it is related to manufacturer. the 240 is a sandisk, while the 1tb is a PNY.

Looks like i will need seperate power supplies... Can anyone reccomend a better way to combine the seperate power sources into one?

runcommand saves the chosen emulator.

Thanks again for all your help Rascas! This little victory has created quite a lot of happiness!

@herb_fargus Fantastic. I'll check both those links out. Thanks!

Arcade emulation is a confusing beast when starting out.

Basically ROMs will only work for specific emulator versions. For example, Mame 2003 needs roms from the 0.78 romset. You need a corresponding BIOS file for the same romset as well (neogeo needs to be correct version. This was my downfall for a while with neogeo games)

Familiarize yourself with the different arcade emulators in Retropie and what kind of performance and compatibility you can expect. You need to note the versions of each emulator. Then ensure you have roms from that version's romset.

For what it's worth, so far I have stuck with the FBA emulator. It's got good compatibility and performance. Note that generally speaking, the higher the accuracy of emulation, the worse the performance....

@caver01 You are correct about choosing the games you know and enjoy then just having all of them(like I currently do). It just occurred to me I can use Romlister to determine vertical games.

Some info here may help as well:
