@shay90 gpsp needs a bios. Without it nothing will run

Great idea!! I’m so building of of those one I finish this one!

@steve-bamford Not a problem. xroar is a "niche" emulator at best. We gotta stick together. Enjoy. Get yourself a full game ROM set and go crazy!

@herb_fargus correct there is nothing plugged into the usb port at all. I have removed everything to make sure it isn't causing the problem. it is a 3.1a usb charger with a cable that is about 3ft long

Well I've tested Sega CD and 32X on my Pi Zero. I used the overclock I mentioned above but with overvolt 2 instead of 6. Sega CD works flawlessly on FMV games and games that use scaling/rotation. Sega 32X is so close to full speed it hurts, but its not quite there. I'm sure if I could squeeze another 100 MHz out of the CPU safely it would work at full speed. It's funny because I remember 32X working good on my Pi1, just not PSX or above. That was a few RetroPie versions back however. This will eventually be a handheld system so active cooling is not really an option. As a result I will likely have to leave 32X out unfortunately, unless performance improves when I lower the screen resolution for the LCD. Out of curiosity, has anyone ever pushed a Pi1 or Pi Zero to 1100 MHz? If so was it stable? How about temperature under load?

@delphiboy

Hmm, uninstall and reinstall that emulator.

@hurricanefan It was only $3.99 lol. Works great!

@thedatacereal said in Pi Zero and Performance... Can anyone clear it up?:

My pi zero runs snes perfectly fine with a standard PI 1/zero build

This probably depends on the game and the personal "perfectly fine". Zelda 3 on SNES had < 45 fps in the starting area outside the house on 1080p. With 720p it has nearly 60 fps.

@herb_fargus Thanks! I had considered doing just that when I was making the first one, but I decided that I should use up the couple of knock-off SNES controllers I had kicking around. When I made my final template, I actually put the holes for the USB port on both sides so that if I revisit this, I could just make a double USB version. I hadn't thought of a quadruple USB version, but that would certainly work as well.

I've been playing around on my Pi3 to figure out what works and such, and have quickly discovered my 32 GB MicroSD card isn't nearly large enough.

I'm probably going to get 128 GB MicroSD cards for my Pi 3's (though if I see a good enough deal on a 256 GB card...), but I'm trying to figure out how much space I'll need for my Pi 0, and I have one question (because I don't have a second microSD to use for the Zero to test things out atm).

I know that the Pi 0 will probably be more limited with the SNES games, because the SNES apparently needs a 3GHz processor to perfectly emulate, but are there any similar limitations for the GBA?

I know in actual technical capabilities the GBA is better than the SNES, but it is also much newer, so not sure if the same kind of hardware emulation issues would hinder GBA emulation.

@Yamt that appears to be a waveshare clone and should follow the waveshare 32b guide.

very clean

nice work

bringing this thread back from the dead, as i encountered the same issue on my pi zero. any updates?

@edmaul69 Is there no fix?

@ayskura

Installing the non-libretro version of pcsx-rearmed gets me full speed with most ps1 games on a pi zero w... The problem is you have to manually set it up and i can't find any good guides (controller and directories don't seem to auto setup correctly so it doesn't find bios files and doesn't have a controller set by default).

@gizmo98 said in Question: Working with Pi3 and Pi Zero:

Run RetroPie-Setup with "sudo __platform=rip1 ./RetroPie-Setup.sh" for pi zero.

Crap. And also big thanks. I'm going to rebuild and do that.
