Raspberry Pi 4B 4GB and the Sega Saturn

@notthesame thank you very much, as I said I will wait as I am not that advanced, how does Marvel Super Heroes Vs Street Fighter or Night Warriors work? When the issues get fixed and I could get it from the script if both of them work I would be set to play a little bit of Saturn :)

Just making this clear because there is a tendency of people exagerating the "good" state of saturn emulation on pi4 :
- i didn't hear of a single game that run full speed on pi4 if you disable the auto-frameskipping, meaning some games might run "full speed", but that's at the cost of non-smooth animation since they won't render every frames
- expect 3 frames of input lag as the best case scenario, i've seen some of those games going up to 7 frames of input lag
- lots of those games are arcade games already available on mame/fbneo, with far lesser input lag (sometimes down to 0 with runahead), no frameskip, and no known glitch. another part of those games is available on psx, in a far better state of emulation too.
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.

@barbudreadmon got it, thank you very much, sadly neither got a port to the Capcom CPS Changer with practice mode included, if they did I would pick them there instead of the inferior PS1 ports because I like fighting games for the training mode
-
@sergioad you could probably make something similar to a "training mode" by using cheats
-
@barbudreadmon I will check it out

i'm never too sure what people like about those training/practice mode, but if it's only about having infinite everything to go all out, i know pretty much any fighting game has cheats to allow that, using cheats might be less convenient than having a practice mode though, idk.
-
@barbudreadmon it is not only having everything, but having an inmobile punching bag and being able to swap characters on the fly

Here's an appropriate challenge (skip to 37:45)
SEGA Rally Championship was one of the bottleneck titles of the system. If you can get it to run on a Pi, you can automatically run anything.
I think the issue is that nobody made any special Dynamic Re-compilers for any of the Emulators. Saturn Emulation has always been heavily CPU reliant.

You are wrong though.
This video is the perfect illustration of how bad sega saturn emulation is on pi4 despite the fps counter sometimes being close to 60, it's crazy how high the auto-frameskipping gets, i'm wondering how many frames it actually shows out of those nearly 60, feels more like using microsoft powerpoint at this point, 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.

yabause has had an sh2 dynarec forever.

Yeah, furthermore the bottleneck for saturn emulation has always clearly been the rendering part with its 2 VDPs. Pi4's GPU is just way too lacking to handle that...
-
@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.

Perfectly playable on my RPi4 .. no frame skipping on or flickering fireballs

Have only test Night Warriors ... runs pretty good using lr-yabause with no frame skipping on :)

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 ?
