@MCG_1983 Shaders work fine on old systems also. Please stop spreading misinformation in various topics or I'll consider you're just spamming.

@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.

@kiddzeal if you update to the latest retropie (you'll need to start from a fresh image at this point) you can try the experimental new psx emulator 'lr-duckstation' which i expect plays this game well (it's been very good for most things).

there's likely little you can do to resolve issues with pcsx_rearmed -it's a mostly abandoned emulator.

@gordonfreemanjr said in Amiberry 3.3 laggy:

I’m having the same issue with Amiberry: slow performance, choppy sound. I followed your advice regarding the resolution, but it didn’t work

Open a separate topic and add your system info, it doesn't seem to be the same issue.

@clyde

I'd install RetroPie with normal NOOBS along with Raspberry Pi OS. But I can't get the RetroPie folder that I can paste in the 'os' folder.

It would be nice to install retropie with NOOBS, but it isn't an option.

We don't support 3rd party images, especially the ones loaded with ROMs. Ask the vendor for support or use the image from http://retropie.org.uk/download.

@Skervix Enable your tv's game mode. That's the best you can do. Run the pi4 at 1080p. I also recommend rtings.com. They measure the input lag of many tv's.

Actually, it did work but instead of adding these lines I uncommented the same in the config file and just changed the values. Thank you very much for you fast and adequate response.

Two little updates now that I have the new Pi in my build.

No more lagging at all that I can discern. Whether the extra0.2GHz made the difference or there is another hardware issue with the other Pi is still unknown.

I figured out the undervolt issue, and it's something I think should be brought to people's attention for future troubleshooting issue with this type of build.

The WaveShare Game Hat I am using has a separate MicroUSB port for charging the 18650 battery you put in it. It seems that this port is NOT meant to EVER power the Pi directly under any circumstances, and cannot transfer full power from it. But because it completes the power circuit, it tries to do exactly that. To run this build on ANYTHING other than the onboard 18650 battery, the Pi's normal microUSB must be used.

Why I didn't think to test that sooner, I've no idea. I'm sure it was not suggested here by any of you who tried to help simply because you were unaware of the device's additional microUSB port - not everyone knows about this device, after all.

The good news for this is that it means I can continue to use the power bank I had been using before - it has an on/off button, allowing it to function as a switch for the Pi, and when plugged into the proper port, there is no undervolt warning and everything runs fine.

I thank you for your assistance, even though we were unable to find the specific issue with the previous board. Perhaps after I build my arcade cabinet with it, something else will come up that will lead us to solve it. But given what the cabinet will do and what kind of games were causing the lag, I don't think we'll be bumping into the issue anytime soon.

@chizzer thanks for the reply ill give it a shot
