Golden Axe (encrypted bootleg) - Sound section PAL dump?

[yavuzg]

I'm trying to repair a Golden Axe bootleg which appears to be the "encrypted bootleg" version (I've checked couple of EPROMs with romident). Everything is OK except the audio is trash. Checked the sound cpu ROMs and z80 which turned out to be OK. I suspect the PAL near the Z80 (sound section) might be the culprit.

I've checked the jammarcade.net and there were 4 dump files from unprotected PALs. The 1. and the 2. PAL were indeed working for my board (checked) but the other files were missing on the site. I mean the links return 404 not found.

I wonder if anybody has the files somewhere...

Thanks

Thanks! Informed the admin at jammarcade and he kindly fixed the problem...

The GALs are working btw...

For reference, the culprit turned out to be not the sound PAL but the NEC D7759
