Thumbs up ;-)

@edmaul69 I know normally you're supposed to just wire the positive and negative ends to the appropriate pins on the control block. They're specifically marked. But im not sure what to do at this point. Thanks for your reply

@Drakaen391 the way retroarch is set up it is probably better to setup like a super nintendo controller and then swap the a and b controls for emulationstation. All emulators using retroarch were set up to set the controls correctly based on that setup and orientate the buttons accordingly

@miran81 there is probably stuff you have to do to get it to display on the lcd. You need to look for a guide for the screen you are using.

So i've finally got further with this issue. I've removed retropie from my SD card and reinstalled it. Added the correct driver and set every GPIO pin in de conf file to 2 so my config now looks like this: gamecon_gpio_rpi map=0,0,2,2,2,2
Interesting enough now all of my controllers seem to work without the 5v mod or extra wires whatsoever. I've attached the NES pad to the PAD 4 pin. The only thing not working right now is in-game. The NES controller works in the menus of retropie and emulation station but not in an actual NES game. Going to figure that out next!

@edmaul69 Yes i have a mouse, gamepad and keyboard attached. It was running on HDMI just to take this picture. The mouse is above ESC button.

@dsfrancis that probably wont work. Rename a file from .bin to .sg . Then restart emulationstation and test. Will probably work that way.

Answered the question myself by just running part one. It seems to work, but man satellaview games are odd.

Thank you for reply.

Hey rbaker, thanks for the response. I ended up reflashing the sd with a new image of retropie. Previously i had retropie installed manually on top of raspbian. This is fine because i really dont use the pi for anything but gaming. I'm sure one of the scenarios you mentioned was the problem. It seems like probably the folder structure was corrupted at some point and no longer being correctly picked up by retropie.. i guess =)
Reflashing with the newest version of retropie worked like a charm, all my original roms work. Now im on to trying to get metal slug 5 to work correctly! xD

@edmaul69 My guide was really just taking the steps from the Raphnet site. Raphnet's site tells you to go to the Raspberry Pi site for some of the steps, so I just put them all in one place.

If you want to load roms from a USB stick, make a folder called Retropie-mount and put into the raspberry pi. It will create folders for roms. Put the roms in the correct folders and restart emulation station. Note, this will not copy to the sd card.

@NastyButtler322 not quite. To the best of my recollection from reading through that code for quite a while a few months ago, what's implemented in ES is a setting that sets a threshold of memory.

When that threshold is crossed, it will explicitly unload textures from memory in order to load new ones. I'm not sure it's as much VRAM in the normal sense of the word as it is a ES texture memory manager, though I can't say for sure as I didn't implement it.

That's why I have a suspicion that keeping it to high is as bad as having it too low, though I haven't been able to get anyone to test that. Too low means it won't have enough memory reserved to render all it needs to. Too high (I believe) will result in white screens if your Pi runs out of memory before the threshold is hit, as it won't unload textures to load new ones.

Edit: see VRAM mention here:

https://github.com/pjft/EmulationStation/blob/master/es-core/src/resources/TextureDataManager.cpp

The method to unload VRAM just deletes the texture from the GL texture manager. The method to remove from RAM deletes the actual texture data from memory.

In the WiFi menu it did not show a network, I tried setting it up and no SSID's were appearing. I reset my router, rebooted the Pi, reconfigured WiFi and tried installing Kodi again. Many errors popped up and after 15 minutes said failed to install. All my other WiFi devices in the house are working fine. I'm not sure what to do.

@marie011101 I've tried that a million times, it's searches for the controller, and the controller searches for the pi, they just don't connect, on top of that being an old build..

@marie011101 3rd party images can't be supported here as we don't know how they've been configured. You'd be best either finding out who Dean is, where he can be contacts and how he has configured this image. Or, the better option, would be to download the official RetroPie image from here and starting with that.
