I had Castlevania Legacy of Darkness running flawlessly, and now it stutters in a horrendous way. The same with CastleVania 64, WWF No Mercy (even with HD textures) I even finished them with no issues, and now they lag a lot.

Now, the Color Buffer to Dram should be sync, Async or off? Also I played some rom hacks and they where awesome, and now they all crash or have lag like a damn mad dog. Hope you can give me a hand here.

For the record, all of these well emulated times where on full screen, and no problems, I don`t know what happened, but now it sucks pretty bad.

Maybe you could lend me your cfg file?

Thank you.

Color buffer to RDRAM = Async

Sounds to me like your issues are from running on the Stock CPU Clock Speeds. Make sure your CPU Overclock is set to High or Maximum Performance when using the Mupen64Plus-Next core.

If that still doesn't fix your issue, then try setting Framebuffer Emulation: False

If that still doesn't fix your issues, then you've probably gotten your config file too far from the defaults by tweaking and changing settings over time. I would suggest loading up "/retroarch/retroarch-core-options.cfg" and removing all the lines that begin with mupen64plus-

That will put your Mupen Core back to the default settings. Then at that point, I would leave all the settings how they are and ONLY tweak the resolution.

Here is what I use...
16:9 Resolution: 960x540 -OR- 1280x720
Aspect Ratio: 16:9 adjusted

Keep in mind that the higher the resolution you use, the more CPU you will need.

You can also still set Framebuffer Emulation: False as well. Using Framebuffer Emulation is quite CPU intensive so you definitely need to Boost up your CPU Clock Speeds or use a Lower Resolution. You might wonder why not just leave it off then? Well that's because it can cause some games to display weird artifacts. For example, if you're playing LoZ OOT with Framebuffer Emulation OFF, and you press PAUSE to go into the Game menu, this is what you will see...

Call me slow but I didn't realise the beetle PSX build seems to be locked to 240p... you can raise the internal rendering, but its more like supersampling, it still outputs a 240p image in the end.

...The only settings that can affect performance in some noticeable way in mupen are frame buffer emu and color buffer to dram. Well, and of course things like resolution and OC. There's no magical cfg that will fix your games all of a sudden. If your game runs very poorly, it's either you're doing something wrong or it is the game's compatibility issue. Other than that, mupen defaults are configured so that the majority of games should run well.

What about overclocking the GPU via sys-clk?

only if you want higher res

Any word on Atari 5200 support? Or directions to make it work?

Can anyone explain about holding the R button thing for RetroArch? Planning to use it for the first time and I kinda don't get it.

With atmosphere, to get full RAM access for homebrews you need to use title override which is done by holding R when launching any title (instead of the title it will redirect you to homebrew menu), that's it.

it runs just like it does on og n64

20fps at best

I'm trying to play MGS: Peace Walker and after I press new game theres no menu text and it gets very broken and I can't progress. I have the PSP BIOS in the correct folder.
I can play God of War: Chains of Olympus normally, although the framerate and audio is very choppy.
Does anyone know why MGS is broken?

I have the same issue, the game always ran badly, but it's a nightmare on switch for me. Also my camera just looks to the floor when I move forward.

You need to get assets for PSP. Try the online updater, assets but I can't remember if you had to get them from somewhere else.

Does touchscreen work on the DS emulator? Mines doesn't work

Ok so the best cores for PS1 and PSP are PCSX ReARMed and PPSSPP, respectively right? I just get the BIOS files and put it in retroarch/cores/system folder right? Are there any settings that I need to fix?

...There's a whole library FAQ for such stuff, and it's written in a way anyone can understand... if you have any basic questions about required bios/assets, format compatibility, folder structure, playlists etc, it's all here -https://docs.libretro.com/

Alright thank you for this. Sorry just a beginner haha

Found a problem though. I applied some patches to my no intro rom Final Fantasy VI (music and color patch) but it's not detected when I scan it. Mother 3 (with Fan Translation) shows up though. Is there a way to fix it?

Do manual scan, don't rely on auto scan.

import manually by editing the playlist

Ok when I'm using the PPSSPP core and try to quit a game, it crashes. I've put the required files in retroarch/cores/system/PPSSPP but it still doesn't work. Though the site says that it should be in retroarch/system/PPSSPP Would that require me to have two system folders?

EDIT: will try the nightly builds to see if anything changes

How are you trying to quit the game? By closing content? If so, then it's ok for ppsspp to crash on closing content sometimes (i remember it did it for me too, but i haven't used it in a while since there's a standalone version)... Cause it is how it is, ppsspp libretro core is not optimized very well (i guess), for psp i'd suggest using standalone emulator, it has better compatibility and better performance overall and no crashes mostly.

As for system folder, you can set it wherever you want in RA directory settings. Its just that all assets and bios files go into system folder, but that folder can be anywhere you want.

Ive tried literally everything I can think of but I cant get retroarch to work properly. I've deleted the config file, Ive done a complete fresh install of retroarch from scratch but I keep hitting the same problem.

When i start retroarch its all fine, I can move around the menus etc and everything is great. But as soon as I load a core, I lose the ability to control anything. Retroarch hasnt crashed as such ( I can still see the clock and battery percentage ticking over etc but the console wont register any inputs apart from the home button or the button to capture an image. Its the same with any core, or even if i directly start a game. What am I doing wrong?
