[5.1] [C2] PSX and Dreamcast emulation problems

dAn0id

Recently I ordered an Odroid C2 to test how good it is for my emulation machine purposes.
I compiled Batocera 5.1 but also downloaded the 5.1 image from the website.
Eveything is working pretty fine, except PSX and Dreamcast emulation.

The PSX emulator is pretty choppy but I don't know why as the C2 should usually have more power than a RPi3.
When trying to launch a Dreamcast .cdi, ES tries to start Reicast, the screen gets black and 2 seconds later it gets back to the ES GUI.

Especially I'd like to know, why the PSX emulator feels so choppy, making all games unplayable?
Is it a Mali GPU driver problem or more an AARCH64 problem?
Anyone else having these experiences?

For the dreamcast, i've (just) answer here :
http://batocera-linux.xorhub.com/wiki/doku.php?id=en:not_supported_emulators
the dreamcast emulator doesn't support 64bit. (c2 is 64 bit)
however, i get a hint that it could be possible to make c2 to run in 32 bits ; so, as soon as i get the time, i'll check this point.
For the psx, i didn't notice this point, so let me retry to play a game tonight or in the next days.
there are several possibilities. in the best case, it's just the compilation options that i set that were not the best.
let me check this point too.

Thanks for the wiki link regarding Reicast. I hoped it was just a configuration problem before compilation 🙁
Then we have to wait for the makers/contributors of Reicast to fullfill this platform switch.

I was thinking about getting a C2 or a XU4 - the XU4 should have been my decision 🙂

I will send the C2 back and get it replaced by an XU4.
Anyway I personally know sraue (OpenELEC founder - we work for the same company) and if you want me to test anything, he can borrow me a C2 😉

damn.
i've worked on the c2 boot.ini while i got a problem.
and it seems i forgot something.

can you edit it, and set :
setenv maxcpus "1"
setenv max_freq "1896"

and tell me if that's better ?

dAn0id

Damn - I just packaged the C2 to send it back to the reseller 😃
I will ask for the C2 from sraue and give it a try tomorrow after work.

After that I will report back.

I got the C2 from sraue today 😉

I did a "mount -o remount,rw /boot" and limited the CPU cores within /boot/boot.ini to "1" while setting the frequency to "1896MHz". Did a reboot and started Tekken 3 and Destruction Derby 2.

It has become better but it's still stuttering - and the sound is still stuttering, too.
The FPS counter shows "34"? - What the heck? It definitely doesn't feel like it's 34fps. It feels more like ~20fps.

Why is that happening? 😃

ok, i'll try these games. however, it is really possible that :
- or the compiling option are badly choosen in the batocera package
- or the emulator is not optimized for aarch64

The psx emulator used in the latest build of Lakka-Libreelec (http://le.builds.lakka.tv/Odroid_C2.arm/) is running PSX games at full speed. Would you like to put the same version of the emulator in the batocera?
The lakka Nintendo 64 emulator is fine too.

hi. thanks. i add it into my todo list. however, several others things to do on the c2.

I own an RaspberryPi 3, an Odroid C2 and an Up-Board. At the moment the RPi3 is my favorit for psx-emulation! The Odroid C2 isnt running very well. But with the next build i will give him new chance!

Dreamcast is the best consoles released by Sega back in 1998. Now there are a lot of best dreamcast emulator in the market which we can use on Windows 10. Like DEmul, NullDC/Reicast, Redream, and Lxdream. You can read the features of these dreamcast emulators and then select which one is looking best among them. We also need to keep in mind budget. https://appuals.com/which-sega-dreamcast-emulators-to-use-on-windows-10/

Hello!
Sorry for bumping this old thread, but i was wondering if you did add to your to-do list putting the same emulator version from Lakka for the PSX and N64 into Batocera...
PSX is really a great console like n64, and it's too bad that these two doesn't work perfectly on C2 Batocera...
Thanks for the answer!
