Sonic 1 is stuttering every now and then on VGA (have not tested HDMI), PAL.
It's micro stuttering (background hanging or skipping a frame?) and even visible in demo mode if you don't want to play for yourself.
I've also noticed it in US Mode but its not so often.

I'm having audio quit randomly for a split second, happening maybe once or twice a minute, on just about every game I tested over HDMI. I can't reproduce it with any consistency. I'll keep playing around with it and see if I can't provide you with better info.

does it happen only on latest release? Do you use native video output through VGA or scaling (vga_scaler=1 option)?

Hm. I tried the last 6 Cores now and also the last 3 MISTer files.
Its always stuttering.

Maybe it was always there in PAL 50hz and I always used US before, because my Sony PVM can display both.
But I decided to play it as it was in my country and renamed the file extension according to their region 2 weeks ago.

May it be possible, that the refresh rate for PAL is not 100% ?
Refresh rate: 59.92274 Hz (NTSC), 49.701459 Hz (PAL)[24]

Regardless of that, great work. Thank you! :wink:

regards,
PhantombrainM

P. S. : ive played around with some games. Its also clearly visible in Mario 3 (R), I know its not an official game but its easy to move left and right and you can see the same stutter like in sonic. Its maybe easier to see there and seems like a fps screen refresh problem.

Yup, can confirm it. If I start the latest core, the sound is not available in any core. Something went wring with audio sync this time.

"Evander Holyfield's Real Deal Boxing" and "Greatest Heavyweights" Neither seems to play.

Audio is still dropping randomly, just not as often as I initially thought. Seems to happen every 2-3 minutes. Wish I could provide you with more info than that.

Edit: The Audio cutting out is happening to the TG-16 core also. So its not a Genesis core problem.

I didn't add latest JT12 as it still has compete mess of FM music in Titan 2. Hope it will be fixed soon.

Every now or then sonic 1 Level title screen gets garbaged. This time Im playing sonic compilation but also had it when I tested the other core builds a few days ago with sonic rev 00 and 01. It just happening since core 05112018.

You can start the game and sometimes it happens or not. Also sometimes after going into the next level like my screenshots (was okay at the first level).

When this happens the font is also diastorded and the rings have messed up graphics until you reset completly or power cycle. I'm playing in PAL.

What did you mention? Sorry, I don't know what you are referring to.
I also haven't seen your question before. Did you edit you post?
I'm using vga_scaler=0

kind regards,

Thank you for clarifying Sorgelig. I read it somewhere but I don't know when and where it was. At least I can say that PAL is not okay like stated above. So same problems.

2 Bugs I found

1. World Series baseball 98 - the ump never says "strike 2"
2. Golden axe - The dwarf most powerful magic attack doesn't make any sound.

Thanks for all your hard work!

In new release Clue can work without fast VRAM access if run in PAL mode.
All games with sound problems need to be re-checked as new JT12 includes many fixes.

Thanks for the Genesis core update! :D

A minor issue I've noticed unrelated to the update:

* In Toy Story there's a glitchy horizontal line the runs through the majority of the screen at around the height of Woody's waist

you have to use VRAM access rate: Original to have correct scrolling.

Currently only one game requires Fast access - Clue in NTSC mode (in PAL mode it works with original rate).
