Hi all,
I have a S16B Shinobi that had a encrypted Z80. A sound issue arose after replacing the battery Z80 with a standard one and using decrypted ROM "EPR11287.a7" from Retro Clinic/leopardcats
Missing drums/bassline on track 2 (Marylin stage) when main synth lead comes in at 0:08
issue was replicated in MAME using "shinobi2" romset and "shinobi_z80" decrypted ROM.
you can hear the issue in this video: listen from 13:04, you can clearly hear that some drums/bassline are missing at 13:08

It should sound like this instead:

My PCB info: Shinobi S16B 833-6496-04
ROM PCB 171-5358
My guess is that it's a bug in the decrypted ROM, it seems it was released in 2003 so am not sure who to report this to or who could fix the bug.
