Gamecube x86 64

leo_kendall

how do you setup the game cube emulator. I placed a few iso roms into the right folder and when i click on them the screen goes black then back to the main game selection again. i tried placing ipl.bin bios in the bios folder, but nothing seems to work. what am i doing wrong?
Thanks

nadenislamarre

hum, i never seen it not working while there is nothing to do.
2 main possibillities :
- be sure you installed x86_64 et not x86
- be sure your images are not corrupted

i guess that you'll get more information by checking the file in logs/stderr*

nadenislamarre

ok. it seems you're not alone.

@mathema
what i suggest :
1- reproduce the issue.
2- show me the logs
3- in the log, there is a command displayed with dolphin. ssh the batocera, and try to run this command prefixed by DISPLAY=:0.0 to see if you can get more details about the error.

i'm really new to all of them. and i'm not to familiar with linux commands.
Everything works besides the sega dreamcast and the gamecube emulator.

What steps do i need to do?

leo_kendall

i am trying to install this on a harddrive also and i am using batocera-20170130.img 64 bit

What programs do i need to download and install, i do have winscp already installed and can log in with that no problem.

Just tryed on another computer a core i3-4160 still not loading gamecube or dreamcast roms / iso / cdi files

nadenislamarre

for the dreamcast, it requires a bios.
for the gamecube, i just think to a bad rom while there is no really reason it doesn't work.

leo_kendall

tryed a number of iso from different sources. I give up on it.

Same issue as leo. I'm going to throw a discrete video card in this unit and see if it fixes anything...the on-board Intel GPU on this is pretty old and probably not supported by Dolphin.

Not sure what's up with Dreamcast...BIOS files are where they need to be and the screen flickers as if it wants to launch the game, but it doesn't. Game files are fine as they play normally under Reicast for Windows.

I'll try and dump some logs tonight or tomorrow as they'll be more helpful than the "it's not working" rant.

gpus i tryed
asus p5n73-am onboard
hd5450
hd7000
gt730 ddr3
gt730 ddr5
8500gt
760gb onboard
intel hd4000 nonboard.

all same everything works besides gamecube and dreamcast and did place the dreamcast bios dc_boot.bin and dc_bios.bin in the bios folder.
sega Saturn and psp works fine.
I like to post some loggs but not sure how to.

leo_kendall

think the problem is that all of my graphic cards i have isn't supported open gl problem.

export DISPLAY=:0.0
./dolphin-emu-nogui -e /recalbox/share/roms/gamecube/Mario\ Kart\ -\ Double\ Dash!!\ (USA).iso
GPU: OGL ERROR: Need OpenGL version 3.
GPU: Does your video card support OpenGL 3?
Segmentation fault

Seems to be an OpenGL issue as you suspected...odd since this card supports OGL 4.5 according to AMD (AMD Radeon HD 8490)

nadenislamarre

it looks like something like this.
i've to found the prerequisite to be able to confirm which computer works/ which one doesn't, and display in the menu the information to not have to search each tmie.

Perhaps this driver only supports OpenGL 2.1 on these cards? I've thrown in a mix of older AMD cards with OGL 3 support or better. Unfortunately, none of my older NVIDIA cards have anything beyond 2.1. Gonna try the GTX 960 in my gaming rig as a last resort, but still dead in the water with the three AMD cards I have.

UPDATE: The NVIDIA GeForce GTX 960 is not a supported card (EmulationStation UI is SLOW), but Dolphin DOES launch games successfully unlike the AMD cards which just segfault.

@nadenislamarre - Any chance this could help address why Mesa is only offering OGL 2.1 support for AMD GPUs? http://superuser.com/questions/964099/correct-opengl-version-on-a-notebook-with-two-amd-gpus

Hi All,
I was wondering if a solution has been found yet for this issue.

leo_kendall

under windows most if not all mt gpus support opengl. Dreamcast, wii, gamecube runs perfect. even the wii u emulator almost plays, but really choppy. This is all under windows like i said. must be a driver problem. the gt series, gt710 720 730 and the amd hd 5450 are all low profile gpus that many people places in the htpc.

I have an asus graphics card and my gamecube emulator does not launch I have the same problem with the black screen. Has it a soluition ?

nadenislamarre

in this beta version :
http://batocera-linux.xorhub.com/upgrades/x86_64/beta/last/

i've made the nvidia support better. it should fix some cards.

nadenislamarre

in the next beta, i'll add a better support for some other cards.

I Can Confirm Beta Upgrade Works Wii, Gamecube And Dreamcast Will Now Launch, However My GTX 750ti Is Not Supported Yet So Both Games And UI Run Very Slowly. Also A Hotkey Needs To Be Mapped For Dolphin As There Isn't Any Way To Exit Emulator Currently. Cheers nadenislamarre For All The Hard Work

esc key from the keyboard for the moment for the wii.

Retrotrigger can you do /recalbox/scripts/recalbox-support.sh and send me the .zip file so that i can see the error about your card please.
