I think I found a timming issue with the arcade card emulation that seems to affect a small number of consoles (the ones that are especially noisy). I need to have a deep look at the acard processing to try to solve it and filter noise. Acard is very sensitive to glitchy accesses because address is modified every access, so if a glitch happens, thr address is mistakenly incremented and data goes to wrong positions
That's great to know.
Do you have any news to share? It's a blocking issue for those using Coregrafx..

As we approach a year after the last update on this... any progress on fixing the arcade card emulation, or at least a way to disable it to actually use real arcade cards to bypass the current glitches?

Also, the issues are not related to the more noisy consoles like neodev suggested August 2019, they happen all the same on the least noisy ones (SuperGrafx).

PC Engine model: Core Grafx I
Power Supply: TRIAD
Video cable: SCART RGB (SEGA Mega Drive 2 RGC)
SD card brand: SanDisk 400GB
Region modded?: No
Jailbar Fix: Yes (MST)
SSDS3 Revision 1, 2 or B?: Blue PCB
In Game Trigger enabled in the Options menu?: OFF
Enable Arcade Card:: OFF

Problem or Issue:

Ranma 1/2 (Japan)

Blurpy audio / freezing when fighting a particular enemy throughout the game. Him executing his attacks causes the blurpy glitched out noises to happen. Changing gender or going through particular cutscenes when this happens freezes the game completely.

Chapter 3 is when it occurs and there is a password to get to the point.

Kunou (Blue robe)
Panda (Panda legs)

in the KAO Pass screen.

I've tested the game on emulation and did not have the problem. Using the Redump dump.

Update: Reripped the game with Turbo Rip. I don't think it's a CUE sheet problem.

Problem or Issue:

Downtown Nekketsu Monogatari (Japan) [Redump release]

When you go into particular shops and exit. You'll hear other audio that's not supposed to be played. Didn't happen to me on Mednafen. I'm wondering if it's the same problem that's affecting Ranma 1/2.

That does happen on Mednafen and other emulators when the speed is set to "fast" and the shop is exited quickly.
This is related to CD head seek timing not being observed.
