Any chance you’d be into working on a gpsp_libretro.so that will work!?
hey
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 https://github.com/libretro/gpsp
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 ?
XMB kills the battery real quick I think, as well… but it is damn sweet.
Bumping this thread also for picodrive libretro core:
alright so there is a new image, gonna try it out, adjust and maybe build mupen/ppsspp

aaaaand… not gonna happen, doesn’t even allow XMB with lima so PPSSPP will not work
so I configured with these parameters now:
./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 --disable-discord --disable-langextra --enable-mali_fbdev
make && sudo make install
then I ran this on ssh:
sudo usermod -a -G input `whoami`
Then I changed my drivers to:
- input: udev
- joypad: udev
- video: gl
then I run
sudo chvt 2
retroarch
Now it’s using mali, but it’s inconvenient to say the least.
This is all with cores from the RA updater:
- Beetle NeoGeo Pocket is full speed now (it wasn’t before), it has a weird issue with some stuff being cut out of the frame though
- mGBA is full speed (it skipped frames before)
- snes9x mainline is fullspeed
- gpgx is not fullspeed
- pcsx rearmed: sloooooow, not built with neon, gotta build it proper
- picodrive crashes, gotta build it properly I guess

ok, I’ll post a small guide on building cores, so hopefully someone will make a repo of cpi enhanced cores:
always run this first:
export TARGET=~/.config/retroarch/cores/
mkdir -p ~/repositories/cores
picodrive working perfect, full speed on sonic 3
cd ~/repositories/cores
git clone https://github.com/libretro/picodrive.git picodrive
cd picodrive
git fetch origin && git reset --hard origin/master
git submodule update --init
make -f Makefile.libretro -j2 platform="armv neon hardfloat"
cp -v *.so $TARGET
pcsx_rearmed working perfect, full speed on ridge racer type 4
cd ~/repositories/cores
git clone https://github.com/libretro/pcsx_rearmed.git
cd pcsx_rearmed
git fetch origin && git reset --hard origin/master
make -f Makefile.libretro -j2 platform=classic_armv7_a7
cp -v *.so $TARGET

Thank you so much for this!!!
Seems mali only works with GL instead of GLES with this lima driver
Shame, because that means no mupen, no PPSSPP.
If I force GLES
[ERROR] [Mali fbdev]: EGL error: 12297.

I tried to build mGBA more ways then one and it just wouldn’t run 100%.
I just used the one from the online updater
I’m talking about before the GPU update. 0.2.
I haven’t messed with 0.3 to much yet
My flavor of picodrive core is built with the following params:
make -f Makefile.libretro platform="armv neon hardfloat" -j4
Don’t know if it makes any difference better or worse comparing to yours build command
make -f Makefile.libretro -j2 platform=raspberrypi
On thing to note is that raspberry platform builds for armv6 (GameShell’s cpu is armv7) and without neon
You’re right that’s better, updated!
