Pi Zero so slow it does't even run NES at full speed

Sage Freke

@barbudreadmon I understand now, thanks for the explanation, I got the wrong impression by reading stuff online.

I had the Pi Zero laying around and I just thought of putting it inside a NES controller.

Yeah, that's the kind of DIY project where you would want a pi0, does it fit though ? I don't remember my nes controllers having lots of spare room.

Sage Freke

@barbudreadmon It should fit by cutting something here and there (don't worry, I'm not using an original NES controller), but I'm not at that stage yet, I want to set the software side first.

Although, after a bit of playtesting I'm starting to have second thoughts: the NES d-pad is tiny and very close to the left edge of the controller, I'm having trouble going up and down in a straight line (I never used one before so I didn't know what to expect).
I may end up using a SNES controller, I have some retro-bit replicas laying around.

Make sure you’re using the fastest emulator for slower hardware. If you’re running Fceumm on a pi zero you definitely won’t get full speed, but nestopia runs just fine.

@capeman lr-quicknes is the fastest. it’s the default for pi0/1.

nestopia run about 30% slower than fceumm on my computer, so i can't imagine how it could run fine on a pi0 if fceumm doesn't

@barbudreadmon I tried nestopia and I gained 10fps in Alien Syndrome (from 40 to 50, still not playable though) but Castlevania runs a little slower this time: 49 instead of 53. I'll keep using lr-quicknes.

barbudreadmon

@sage-freke Weird, on my computer nestopia is slower on Alien Syndrome, but yeah there could be discrepancies between games since they use hundreds of different mappers (some kind of special chip in nes cartridges, with different levels of complexity, the emulator needs to emulate it)

Try flashing RetroPie 4.3 instead. It runs loads faster on the Pi0 as its not as bloated since the newer versions that are more concentrated on the newer, way more, powerful Pi's.

4.3 still feels like the latest RetroPie with most of the ES features with themes etc but everything is a lot lighter on resources.

I still had to change MegaDrive to the Picodrive core though for full speed MD.

@dynamight picodrive has always been the default megadrive emulator for pi 1/0. pi1/0 versions of retropie don't really have any emulators/software related to other pi models installed by default. that's why there's different image downloads.

emulators can increase in accuracy and requirements, but the ancient versions used for pi1/0 shouldn't.
