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/"

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.

Understood. I'll take another look at the overlays or doing a fresh install and copying ROMs into place.

As I expected, the overlays works properly at 1080p, so if others are having overlay obscuring part of the screen using a lesser resolution (4:3 in particular), 1080p is one way to fix it. ;-)

Wow... Thank you. For anyone curious, this worked. Updating Rasbian tools packages provided new firmware needed for the image to boot on my Raspberry Pi3....

Thanks BuZz!

I also must say, that I like the new retropie setup script. With it, I was able to update the base install, then seperately update the underlying OS and Firmware.

Whats really great is that I am now on the 4.0beta, and my Xbox360 Wireless controllers still work perfectly (which they did not when I attempted a fresh install of 3.81)

Seems the new retropie setup script seperated the installation of underlying OS from the base install, while keeping driver updates seperate as well (giving you better choice of what gets installed)

Cool beans.

@BuZz Yeh I think I will have to to be fair I use it with my phone for VR games which is what I got it for just thought it would be cool if I could use it for this as well.

Thank you for all your help.

Thx. Figured it out and just updated ScummVM. Hopefully that didn't introduce any issues elsewhere. Thx

There was a bug with the RPi 3 bluetooth but it was fixed in kernel 4.4 and RetroPie 3.8. Apart from that I am not aware of bugs with Playstation controllers. If you are still experiencing problems, post your Kodi log and the output of dmesg.

It didn't like something. I no longer use save on exit and just save new configs and edit the files if needed.

You can use the configuration editor from the RetroPie menu to adjust most common RetroArch settings.

I had that issue early on before I learned to manually edit files. Not sure if I just missed something easy back then or what. In the end, once I learned to manually edit, it was easier to understand the underlying fie structure and how things worked. Now, it's second nature to make changes either via the files or the retroarch configs within ES.

Great reminder that you can edit stuff within the menus (I'm just oldschool, so SSH is comfortable).

@BuZz, @username97
A little late to the party here, but in case it helps anyone else, I've written a comprehensive guide to installing RetroPie manually on top of Raspbian, including the changes introduced in the new, far more flexible, version 4 Retropie-setup script:

RetroPie Manual Installation Guide, including the Version 4 Setup Script Revised Menu Structure

It doesn't say packets. It says "Packages" - which is a pretty common term.

thanks herb, yes i got it working and added games for some reason i can't add all the spectrum games but did all the c64 with no problem. my only new issue now is the controls...spectrum the controller i have works fine but not easy to get back to the retropie menu...c64 controller does not work and keys are so scatted i don't which to press and only way to return to retropie is to unplug the pi.

at least i am almost there :)

you can save every time you exit - it's a retroarch/libretro function. however there is currently an outstanding issue with it: https://github.com/libretro/RetroArch/issues/3049
