Black Screen

[Dako9767845]

Ok, so I loaded some arcade games and suddenly I got a black screen, I've happened to me before but I have to do is turn off the hiscores and it worked but now it just showing me noting a black screen and with sound

I have all the bios and the games I loaded have worked before and I don't know why it's happened to me again

[Dako9767845]

I fixed it, I just had to do is change the windowed scale and we good to go

I reinstalled RetroArch 1.15.0 yesterday, I loaded 7 games and only one did show which Is DonPachi but other than that it just giving me Black Screen with sound

Read https://docs.libretro.com/guides/arcade-getting-started/ and https://docs.libretro.com/library/fbneo/

If, after following the documentation, the issue remain, please write a proper issue with logs, informations about your setup, information about the games you run, ... I'm not interested in playing guessing games. Closing.

I've followed the guides but ever since I reinstalled the emulator. The screen just go black as the audio is playing

[barbudreadmon]

paste FULL logs

... or use the correct romsets as the documentation is telling you to, since your issue is most likely about incomplete neogeo bios and the logs are most likely telling you about it.

There the west of the logs

[barbudreadmon]

Those logs are still incomplete !!!

Specifically they don't allow me to confirm whether the bios you are using, "MVS Asia/Europe ver. 5 (1 slot)" aka sp-s2.sp1 with a crc of 0x9036d879, is present in your neogeo romset (and tbh i think i already know the answer to that question).

In the first place this is not the default bios and you shouldn't have changed it. Your black screen issue is typical of people who changed bios setting while actually not having the corresponding bios in their neogeo romset.

Would you please follow my instructions for once ?

here's the thing though before I reinstalled the Emulator, I just need to windowed scale and work. also changed it back to the default bios. still Black Screen

Now that we finally stopped the guessing games, i can see it wasn't about the neogeo romset, and i'm noticing 2 weirdness :

[INFO] [Video]: Average monitor Hz: 8.233163 Hz. (28.534 % frame time deviation, based on 2048 last samples).

No idea what this is about, but retroArch is reporting an abnormally low refresh rate for your monitor.

[INFO] [GL1]: Found GL1 context: "wgl". [INFO] [GL1]: Detecting screen resolution: 1680x1050. [INFO] [GL1]: Using resolution 960x720.

It seems you set gl1 as your video driver in retroarch (this is not the default), you probably shouldn't do that, maybe there are compatibility issues when using that 30 years old version of opengl. Specifically i'm not sure opengl 1.0 is compatible with the 32-bit color depth used in neogeo games but not in donpachi.

Possibly, if your machine can't use the gl driver because it's so old that it's not compatible with opengl 2.0 which was released 20 years ago, try disabling the "Use 32-bits color depth when available" core option, which will convert 32-bit colors into 16-bit colors. While 32-bit colors are required to avoid some gfx issues in certain games, 16-bit colors might at the very least improve your situation.

Anyway, that's a setup issue probably related to your gpu, not a core issue, so i'm not gonna be able to provide additional help.

ok, I've turned off the 32-bit color depth didn't work but I turned on Bilinear filtering and it worked. thanks anyway for the help.

Bilinear filtering

If blurry graphics is the best retroarch can do with its gl1 driver, i'd recommend using FBNeo standalone instead, one of our devs was still using a pentium 4 running windows xp until recently.

turned off the 32-bit color depth didn't work

The only other difference i can think of would be that donpachi is a vertical game while windjammers is not, but it doesn't really make much sense though i'd suppose you tried non-vertical games with other cores and they worked. I might have been better at guessing something if you had answered to my question about the games you tried running.

[Dako9767845]

Ok, I'm having fps issues, here are the new logs. idk why it is working for me because has worked before and now it just doesn't
