Raspberry Pi 4B 4GB and the Sega Saturn
-
@barbudreadmon So, being realistic, we can't expect Saturn emulation to improve until the next generation of Pi computers?
-
@zering I suspect a big part of the problem to be in pi's GPU drivers, but yeah having a superior GPU (assuming pi5 will have that) would certainly help. Otherwise you could also consider buying a better SoC, like the odroid n2 which was available long before the pi4.

@barbudreadmon said in Raspberry Pi 4B 4GB and the Sega Saturn:
it's almost hilarious in street fighter alpha 2 (one of the saturn 2D games reported as "being perfectly playable" on pi4 ?) when the flickering fireballs sometimes won't even be visible due to all the visibility frames being skipped.
Perfectly playable on my RPi4 .. no frame skipping on or flickering fireballs
-
@barbudreadmon said in Raspberry Pi 4B 4GB and the Sega Saturn:
All of this to say : "Marvel Super Heroes Vs Street Fighter" and "Night Warriors" are perfect examples of games you should never even think of playing on yabasanshiro.
Have only test Night Warriors ... runs pretty good using lr-yabause with no frame skipping on :)

@dreamcastkid said in Raspberry Pi 4B 4GB and the Sega Saturn:
no frame skipping on or flickering fireballs
One of those statements is false.
Just to be clear, the fireballs must flicker, they do in all 2D street fighters afaik, flickering was an effect used to fake transparency before 3D systems, it is about showing an element for 1 frame then not showing it in the next one, and repeat.
If your fireballs don't flicker, then that means the frames when the fireball is invisible are skipped, and you have frameskip on. -
@barbudreadmon Sorry, but that video was horrible. I compiled a version of Yabause/Sanshiro last year/early this year and played Sega Rally significantly better than that and that was just a goof to see what was could be done.
see link below.
So don't get too down based on that video.
Found the old thread: https://retropie.org.uk/forum/topic/24568/is-yabasanshiro-emulator-coming-on-retropie/268?_=1613102464587
Follow the instructions there(you will have to piece them together somewhat but its not that hard) and you should be able to build a standalone yabause/yaba sanshiro that plays sega rally decently. Not completely without frame skip but way better than that video shows.

I know the situation, actually i was the one who recommended to use standalone and to forget about the libretro core i wrote.
With standalone version it will be significantly faster :- because you won't have to go through the libretro api for gl rendering, the most significant overhead you'll get with a libretro core over its standalone version is when opengl/gles is involved
- because standalone version of yabasanshiro is offloading part of the rendering to a subthread, which is something impossible to do with the libretro api
-
@barbudreadmon How do you go about installing the standalone core on the pi 4?
-
@zering clone the pi4 branch with
git clone https://github.com/devmiyax/yabause.git -b pi4then follow the steps at https://github.com/devmiyax/yabause/tree/pi4/yabause/src/retro_arena#retropie-on-raspberry-pi-4 to build it ? -
@barbudreadmon Thanks. I've successfully cloned the branch but when I try the first cmake command I get a bash command not found error. Is it possible there's an error in the syntax?
-
@zering i think that command line expects you to run https://github.com/devmiyax/yabause/tree/pi4/yabause/src/retro_arena#get-source-code first
-
@barbudreadmon Thanks, I got it working. Very impressed with the results. Finally I can play Panzer Dragoon Saga again!
-
I followed the instructions to install standalone yabasanshiro for my Pi 4, and it's up and running. I tried a couple of games, and they work great! However I'm having one minor issue I'm hoping for help with. It says in the README that select is hard mapped to Show/Hide Menu, but even after mapping select manually through keymapv2.json in ~/.yabasanshiro, it's not recognizing select on my controller. I can only open the menu with Esc on a keyboard. Also, I need to use a mouse to navigate or interact with the Yabasanshiro menu. Is it possible to do this with just a controller? Sorry if this is a dumb question or one that has already been answered.
-
@zering I've done something wrong here.
Is this the order of code?
$ apt update $ apt install -y git python-pip cmake build-essential protobuf-compiler libprotobuf-dev libsecret-1-dev libssl-dev libsdl2-dev libboost-all-dev $ git clone https://github.com/devmiyax/yabause.git $ cd yabause $ git submodule update --init --recursive $ mkdir build $ cd build $ cmake ../yabause -DGIT_EXECUTABLE=/usr/bin/git -DYAB_PORTS=retro_arena -DYAB_WANT_DYNAREC_DEVMIYAX=ON -DYAB_WANT_ARM7=ON -DCMAKE_TOOLCHAIN_FILE=../yabause/src/retro_arena/pi4.cmake -DCMAKE_INSTALL_PREFIX=/opt/retropie/emulators/yabause/ $ make $ sudo make installI get all kinds of errors on the cmake line:
CMake Error at /usr/share/cmake-3.13/Modules/CMakeDetermineSystem.cmake:100 (message): Could not find toolchain file: ../yabause/src/retro_arena/pi4.cmake Call Stack (most recent call first): CMakeLists.txt:1 (project) CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage -- Configuring incomplete, errors occurred!It was going smoothly until then, I thought I was on to a winner!

@adambegood you need to add
-b pi4to the git clone command -
Hey
im trying to update lr-yabasanshiro
But im getting this error -
Help ? :) -
@barbudreadmon Okay, thank you so much. I could have realised that, it was written elsewhere.
I've deleted the home/pi/yabause directory, but I still get
root@retropie:~# git clone https://github.com/devmiyax/yabause.git -b pi4 fatal: destination path 'yabause' already exists and is not an empty directory.Any idea how I reset that? Thanks very much for the help.

I already have it
i just cant update it -

root@retropie:~#prompt, you aren't in/home/pifolder, you are in/rootfolder, and you probably have a/root/yabausefolder.
