VA0 Jap Not even a single game works properly, plenty of sound glitches #209

VA0 Jap NTSC BIOS 1.00 Bought an "elite" blue board version of SAROO marked as 1.66 (172-6879-02) 2024-04-18-DJF A random sound glitches can be heard right after a game start, or few minutes later, and after several minutes game freezes. Any game I tried. I tried to isolate pin 7 on the CD-ROM controller board (or whatever it is) like on this video: https://www.youtube.com/watch?v=nWIs6qGuU84 tried different SD cards, different filesystems, different cluster sizes. Tried to disable Phantom modchip. Nothing helps. You should warn people that SAROO doesn't works with VA0 with big red text

Browse here. After the above methods, the VA0 SATURN can be used normally. If there is still noise, please try cleaning the card slot. Or use a CD to test if the SATURN is functioning properly.

SAROO can be used for the VA0 SATURN. Please confirm if there is any malfunction with the SS or SAROO hardware

Can I do something besides cutting traces to test if it really helps? As I said before, isolating pin7 has no avail to me at all. It is highly unwanted to damage a good rare system even in a little reversible way. I cleaned SD card slot, and the console runs CD backups with Phantom chip like a charm, I've never had any DRE, looks like the drive and a whole system is a virgin one.

Maybe lifting of some specific pin will do the job? I have enough soldering skills for that.

Lift up the 14PIN of IC17 and remove FB8, then directly connect the 14PIN of IC17 and the 2PIN of IC24. The shorter the wire, the better
