RetroArch Megathread



Hi everybody!

Today I flashed a new SD card and I’m trying to reinstall Retroarch from this guide. Mind you, I had already done that successfully on the original SD card. But this time, when I execute:

I get a lot of 404 errors like this:

E: Failed to fetch 404 Not Found

And at the end:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
E: Failed to process build dependencies

What should I do?


I still can’t get

sudo apt-get build-dep retroarch

To work. It shows a bunch of 404 errors in the Terminal. I’m guessing due to that this line doesn’t work either:

./configure --disable-vulkan --disable-ffmpeg --enable-xmb --disable-materialui --disable-flac --disable-parport --disable-vulkan_display --disable-videocore --disable-videoprocessor --disable-v4l2 --enable-x11 --disable-wayland --disable-vg --disable-jack --enable-kms --disable-discord

It says that KMS is not available.

Is the server down @fr500?


@uke run this first:

sudo apt-get update

then start over with

sudo apt-get build-dep retroarch


thanks wohali!
works now.


I know this is quite old, but if any one is having issues to get 60FPS for PCSX-rearmed on the gameshell.

Here is a recompiled .so that is compiled on the gameshell, I was able to reach 60FPS for Mega Man X4, the Core Updater .so only managed to get 22fps.

Just copy it under ~/.config/retroarch/cores/ and load it in retroarch and enjoy smooth gaming.


This is great, I was having that issue and could only make it work via the standalone. Will try this later.


@fr500 the link to your files is broken. I need to download your gPSP because the one on buildbot is broken


Any chance you’d be into working on a that will work!?



well… I got quite disappointed at the lack of solutions for GPU acceleration so I haven’t really used my GS too much.
That said the easiest thing to do would be to build it! I think building it in the GS itself yields the best results.
Anyway I’ll check this weekend.


I’m willing to try my hand at that, I just don’t know enough to do so. Im currently reading primers lol

If I build it on the GS, I don’t know how to make the .so library from the .c and .h files.

git clone
cd gpsp
make -j 2


Thanks man. The build was a success! I was however unsuccessful in it running. Same old crashing.

Whenever you have some time, if you could take a peek I’d appreciate it. I can’t tweak it because I don’t know about any of that stuff.

Uhm … I think that 0.21 have lima driver integrated:


Did anyone succesfully install a Sony PSP emulator core and would be willing to do a write up ?
