Genesis Plus GX core returns black screen

Unfortunately Genesis Plus GX core does not work properly. The program crashes when I’m trying to use that core. I took the core from the previous version (1.3.0). It works fine.

Retroarch 1.6.0 Mac OS 10.5.8 PowerPC

Retroarch 1.7.0 I’ve just updated. There is the same trouble. What am i doing wrong?

Do other cores work? I don’t think Genplusgx does anything particularly special compared with any other software-rendered cores.

Can you post a log? You have to launch the retroarch executable from a command line with --menu --verbose --log-file log.txt

fceumm_libretro works fine

Hmm, ok. Do the games have audio and just no video? How many games have you tried? Can you try some verified No-Intro dumps?

Also, why do you keep editing your post? I keep formatting it and then you keep unformatting it.

They have no audio.

What is this?

Sorry. I tried to fix my post.

heh, no worries. Looks good now :slight_smile:

No-Intro is a dumping/verification group. They put out databases of ROM checksums that ensure that the dumps are exact copies of the original ROM.

I found one. Nothing happened.

Just putting in my 2cents. I too an experiencing the same issue. PPC 10.5.8. I’ve tried snes9x and nestopia with no issues. Only Genesis Plus GX gives that exact issue with the black screen. There is no video and no audio. No random crash either. Just a hang with the black screen. I don’t see the archives of retroarch anymore so I cant get the older Genesis GX Plus core. Could I be pointed where to obtain the previous core as mentioned above or instructions on where and how to compile it myself?

Thank you in advance.

You can get the source from the github repo and check out whatever revision you need. It wouldn’t surprise me if just compiling it yourself fixes it, though, which would suggest something amiss with our buildbot.

The latest build (eebbdb2) from http://buildbot.libretro.com/nightly/ works fine.
Compiling using msys64 the latest from Github works fine.
But the latest Appveyor build (windows_msvc2017_desktop_x64) shows black screen.
