4 player wiring & Raspberry 4

The voice of wisdom. Thanks.

Oh, definitely get the 4. It's awesome. The manual install was easy and it emulates like a professional PC. No N64/NDS problems at all. I think it could even handle Wii. BUT it needs a lot of power to run. No piece-of-junk 3 amp PSUs. You want a 3.5 for maximum power.

I have an iPac2 and hate it. The debounce settings are waaaaayyyy too short and it always registers multiple inputs, usually a separate input on both press and release. It was maddening. I recently pulled it and wired directly to the GPIO using Adafruit retrogame software. GPIO input is perfect, but there are likely not enough usable pins for a 4 player setup.

Deciding what Raspberry Pi to buy can be a tough decision.

It is easy to set up a Raspberry Pi 3B+ with RetroPie. You just download the image from RetroPie download page and use a SD Flash tool to flash the image file to your SD card, or you can use PINN which is an enhanced NOOBS to install RetroPie.

If you decide to buy a Raspberry Pi 4B then you can run Lakka which is another emulation software for the Raspberry Pi. It is quite stable as far as i have tested with my Pi 4B 4GB model. You could choose to install Lakka first and use it, then once RetroPie gets officially released for the Pi 4B, switch over and install it.

If money is no problem then first buy the Pi 3B+ and set it up with RetroPie, controllers and such, then later upgrade to the Pi 4B.

Lakka is garbage. It is not as versatile as RetroPie by a longshot.

Lakka is not 'garbage' just because it's less versatile than RetroPie - its developers are doing good work providing an emulation system for a lot of the SBCs out there.

Thanks for all your replies. But I'm still with my uncertainty :-))
I could indeed go for a more future proof Pi 4 and run it with Lakka until Retropie will be compatible and then swap. More work though than going for the Pi 3. Someone told me that the processing gain of the Pi 4 doesn't help that much with emulation, only for some games. Sigh.

That's not true, the PI4 is a step-up in processing and GPU power and it helps a lot with the emulated systems that were not fullspeed or straight up not playable on previous Pi models.

@IceChes1 Well even if it is not as versatile as RetroPie it still deserves a place as an alternative to RetroPie just like RecalBox. @Tim-s-up can also just manually install from the latest branch of RetroPie to a Pi 4B if he wants. I guess it comes down to wheater he wants a stable official release from Lakka, or try using the latest branch of RetroPie which is still experimental if he decides to buy a Pi 4B. Otherwise he will be buying a Pi 3B+

@Tim-s-up The extra horsepower that a Pi 4B provides will still improve performance of arcade games and emulation overall. You should get a mucher smoother gameplay and it will be more future proof in hardware. I can only tell you this, that i have tested both SNES and PSX emulation on my Pi4 4GB in Lakka and it runs really well as long as I choose the correct emulator. To begin with I had some sound issues with SNES emulation, but then i changed to the Snes9x emulator and now it works just as good as my Pi 3B with RetroPie, if not even better.

I have also tested an original Super Famicom controller(SHVC-005) with a usb adapter and it works on the Pi 4B in Lakka like it does on my Pi 3B RetroPie setup. This controller is identical in hardware with the original SNES PAL controller. This gives SNES gameplay a much more authentic experience, just like when you will be using arcade joysticks and buttons for arcade games.

Thanks to all. I just bought a Pi 4. Mainly because it is more future proof. I will play around with Lakka for some time, waiting for Retropie to be fully compatible.
