@shanet94 unfortunately I'm a little dim when it comes to these types of things. I'd love to be able to help but I feel at this point a chocolate tea pot would be more help :) thanks again for your help.

i will try that, originally I chose it because of a few roms that seemed to work better with mame4all,

thanks for the tip I will try it for a while.

no probs! glad it's working on the new install at least.

I'm having the same issue with my n64 games with a pi3 as well

You need to keep them in a .zip format

I was extracking them and you just leave the file in a .zip format and put them in the correct rom location

Also I'm having issues with my x box controler not working with the meme games
When I hit Start Select I can't get out. I have a keyboard hooked up so I can get out but the controls are off for all my games I have tested so far

OK, the gdi to chd program worked, it just expects exact naming, i.e. track01.bin, track02.raw, track03.bin, etc

@edmaul69 that's the problem. I did an update and forgot to add the bios, and had the exact same issue with CTR. Just add the bios and you will be racing!

Haven't managed to get the PS4 controller to work so bought a PS3 controller instead, worked first time.

Answer... Sorry... https://github.com/retropie/retropie-setup/wiki/playstation-1#analog-controller-type

You don't list which emulator. You can switch to ones with hires resolution set in runcommand - https://github.com/retropie/retropie-setup/wiki/runcommand but some games will be slower.

By default we use the original N64 resolution which was low res, although may have looked better on an old crt.

@obsidianspider
you may have some issues in connecting and configuring the buttons of your bluetooth controllers. But once it's done, it's really easy to switch between the available controllers in RetroArch.

Trying to ask your question "how does the system choose which controller to use?" (assuming system = RetroArch). Like I said in my first response, RetroArch define some indexes for the controllers. The default is player1 = index 0, player2 = index 1, and so on (I didn't make it clear in my first post). But you can change it in retroarch.cfg. What the RetroPie-Setup config editor and my joystick-selection tool do is just this: change these options in retroarch.cfg.

BTW: the options related to what we are talking about here are input_player1_joypad_index, input_player2_joypad_index, etc...

I also had the problems with the freezings.
Now I changed the SanDisk ultra 64GB with a SanDisk extreme 64GB.
The problems with psx/psp disappeared.
Also the problems with daphne disappeared.
Before, I had the problem, that the video in daphne pauses for a few seconds, while the sound continues.

Perhaps, somebody will help this!

@kevlar
You are welcome

Works also on my end. Thank you!
