Tuning for playstation on pi zero

gumara

I've pi zero 1.3 (no wifi). It's good for SNES and NES but not for playstation and genesis.

I try overclock but it's can't boot.

So, I thing it might be work if I choose right bios.

Please help, I need to play a playstation and genesis on it.

@gumara a pi zero is not very powerful, but it should work just fine for genesis games using lr-picodrive. As far as PlayStation, the best performance is the standalone pcsxRearmed. It’s not perfect and can lag. The Lr version is just too slow on a pi zero. Depending on your build, you might want to invest in a pi3 or 4 if PlayStation is a priority. Both can run the new Duckstation emulator, which is a lot better than PcsxRearmed.

I got a retroflag GPI this week which has a pi zero w. I overclocked to 1000 arm frequency and have managed to get mario 64 + Diddy Kong racing working with some audio stutters here and there. The vast, vast majority of n64 games are simply too much for it to handle though.

I haven't tried psx yet but I'm assuming I'll need to use the standalone emulator. Same for GBA and SNES, use gsp or pisnes to get better performance. Scummvm also works very well, only blade runner fmvs are stuttery, the actual game is fine. Everything else seems to run smooth (even things like broken sword or curse of monkey Island play nicely).

Also found Sega CD works very well which surprised me given it's quite big files.

I believe that is the stock frequency. Though in my experience the pi zero has almost no headroom for overclocking.

@quicksilver is it? As on my pi zero w, the config boot file mentioned stock was 700? I think they might be lowered the stock clock speed between the regular pi zero and w..?

the comments (lines prefixed by #) in the /boot/config.txt file are there from the raspberry pi 1 days, which was 700Mhz. they have no bearing on the default speed of anything - they are commented out and just there for reference. pi 0 is definitely 1GHz.

@dankcushions ah wow I didn't know that. Still though, not sure I can get much overclock put of pi zero anyway, a few online mention 1080 or so, but I doubt that'll give a significant boost to be worth it.
