Aladdin animation Works if you select "3 buttons only: Yes" in OSD

I just tested the new core "Genesis_20181010.rbf". The problem with the character select screen in Battletoads & Double Dragon is fixed.

But I believe there were also some small regressions. The Bad Apple demo locks up after I try to start it by pressing start. The Japanese version of OutRunners, which was working before, no longer works (locks up with a black screen).

Hey that worked, thanks! That completely fixes both issues in Aladin. Seeing that I'm using a PS3 controller I'll leave that option enabled for everything.

Any secret fix for getting Shinobi III to work ? :D

Is there a list of known issues somewhere so I don't mention things that everyone already knows about?

Here's an issue I discovered tonight: In Joe & Mac the large dinosaur sprites (?) are pretty messed up. You'll see what I mean if you play through the first minute of the game.

I just confirmed that Shinobi III works and Joe & Mac no longer has the sprite issue.

I did notice that 6 button was enabled by default on this new core which creates the issues with Aladdin (only mentioning because the changelog said it now defaults to 3 button)

Also, I can confirm a noticeable graphical issue with this new version with HDMI. If you start the first Sonic 2 level and look at the rectangles and squares below the green ground surface there's now a continuous shimmer/flicker over all of them, even when paused. And this issue completely goes away with the old version. Doing a reboot didn't make a difference.

The problem continues after turning off and on, only happens with version 20181015, if I select the version 20181010 works well

Is it the same issue that I mentioned or something different? 100% reproducible in the same part of a game? What game/part?

Ah, this is probably what you're talking about:

This is a direct capture from Rysha on discord. On my TV it doesn't look this noticeable, but I do see these new artifacts around edges

Sorgelig,

Thanks for the hard work :)

Do you know what would cause the video quality do degrade so drastically in this release?

20181015 vs 20181010 (the "SEGA" is from Sonic US)

Thanks

Strangely the OSD is not affected...

For whatever reason (maybe TV dependent), the graphical issues don't look nearly that bad for me

Download the last release again!
Fixed Jim Power.
Probably HDMI will be fixed for those who got glitches if it's metastability problem.

I'm not sure if anybody has reported this yet, but there's an intermittent background audio crackle that occurs in many games. I noticed it a lot in Castle of Illusion during the intro part and during game play. Others have mentioned crackles in Castlevania Bloodlines and Vampire Killer as well.

Somebody mentioned that reloading the Genesis core seems to reduce the crackling, but I didn't really notice a difference when I tried.
