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:

It appears I used wrong key words for that :)
At-least I was on the right track regarding /etc/profile.d/10-emulationstation.sh

@BuZz that all makes sense, thanks for the reply.

@mediamogul Aboslutely agree on that. I wrote a guide to installing RetroPie using the new menu layouts yesterday: https://retropie.org.uk/forum/topic/1870/i-ve-created-a-new-retropie-manual-installation-guide-covering-the-version-4-setup-script-revised-menu-structure

@FatalXCepti0n

Have you applied an overclock to your SD card?

Using dtoverlay=sdhost,overclock_50=100 will disable your WiFi.

Replace this with dtoverlay=sdtweak,overclock_50=100and your WiFi will come back to life.

Alternatively, if your home network is on a channel greater than 11 you will need to enter your raspi-config (sudo raspi-config) and change your WiFi region to something like GB where these additional channels are supported.

@fulton1 Don't give me any credit for this. I hope this works for you. "https://www.reddit.com/r/RetroPie/comments/2shkdt/configtxt/"

@gorgar

Hmm, that's odd. Does the pi3 still have trouble with the onboard Bluetooth?
Are you running 3.8.1 with a fresh install?

But yes, I plug the controller in at the home screen of emulation station, wait 30 seconds, then press the P3 button and wait 30 more seconds. Then I disconnect the controller.

Part of the problem may also be the controller needs to be charged more. That was another problem I had. Make sure the controller is charged several hours before trying this.
