@diegomaradona21 said in Pi4 performance on Mame with CRT shaders: ok thanks. I meant 2d games actually (maybe plus tekken and soul blade / edge but not a must). Is there any list of games supported by mame in 2003? or maybe which specific version of mame that is? each version of MAME will have a corresponding gamelist.xml or dat file which contains the list of games it supports (however nothing about performance). there are compatibility lists linked in the retropie MAME docs but they are fairly broken right now (soon to be retired), and don't contain pi4 information. soul blade and tekken's playstation versions will run great. any cooling needed? i use the flirc case which acts as a heatsink. never had any overheating issues, but it depends on your room temperature, humidity, ventilation, etc.

I'm afraid we only support the official image. i can see that the top screenshot is using bilinear filter, and the latter is using a shader, neither of which are set by default in the official image. i would strongly suggest you use the official image. if you want to configure image quality on that, the guide is here: https://github.com/RetroPie/RetroPie-Setup/wiki/Shaders-and-Smoothing

@Folly I have tried with the BIOSes and the Hash file for MAME 0.223 On my Pi4. I also tried for other systems (ChannelF, Astrocade, etc.). Mame 0.223 works fine for all systems except CDI. I recreated a .chd with a dummy because of the changes in the Hash file and nothing works.

@ReadyPlayaWon ah yes my mistake sorry. Yeah I was not thinking guys but 3do emulation seems better now, and will get better in time, alot of cool fixes are being done, I finally got a fix for psx on Driver 1 that had a crash after retry, battle chess should be interesting on running, I ran that mad dog and runs great, I need to test more games.

Big update, reinstalled daphne and problem solved !

Oh God, well at least there is an answer! I guess if that is the latest version then no Pi4 compatible version has been produced. Building it from source isn't something I would be comfortable with at all so I guess I'll park this one for now. Thank you so much! Edit: I spoke to the developer on a forum, he thinks the binary is built for a Pi 4.. but says that he hasn't tried RetroPie.

Yes, I figured so much. I was asking if it will ever be available for environsments that are not running X, but I guess as soon as it is ready, people will make the effort to implement it to Retroarch.

I dont know what was the problem first time flashing but formatted and reflashed now its working.

@challenger2010 A bit strange since the filesystem should be the same (ext4) in RetroPie 4.5 and 4.6 resp. Debian Stretch and Buster. But good to hear that your problem is gone. And thanks for sharing your solution.

@quicksilver Awesome thank you! I still get a small part of the screen at the bottom that updates slower than the rest of the game. But that's a minor bug imo and the game is playable, cheers!

I realized I can use my USB2-A meter to test the output from the USB2 ports. Problematic PSU causes it to have 5.3V and the better one has 5.1V. Hopefully it helps anyone else having problems with a stronger PSU.

Does anyone know if the Mayflash N64->USB Adaptor works on Pi? They aren't cheap but can be bought, and I probably have an N64 Controller at home somewhere. Edit: I now realise the original post was for a Wireless controller - so I am sorry for muddying the waters somewhat.

@mitu I tried the runahead out and it was great! Thanks all!

@retropieuser555 said in Mupen64 Plus Next 2.1 Incoming: @akamming heya I just did an update at source and it doesn't seem to have this issue? Maybe try updating now? sorry for late reaction. I reported an issue on gliden64 and it turns out this issue occurs with FB Emu off on PAL games. so now using USA roms and then it works fine. Will hopefully be fixed in a future release.

@quicksilver I did not know that. Sorry, but I can't change that now.

Thanks very much for the detailed reply, it seems like the benefits will outweigh the pretty minimal cost.

@dankcushions Perfect! I'll invest in a bigger Micro SD Card and then give it a go. Thank you so much!
