Sonic Wings 2 (sound issues)

Hi all,

Recently purchased Sonic Wings 2 (aka Aero Fighters 2) as faulty.

After I received it I cleaned the contacts on both boards and popped it in my AES system with furrtek adapter (I have a MVS I just haven’t got a way to play SCART quite yet).

The game boots, however the music track is choppy, cart checker on Unibios says “OK”. Playing the music tracks in Jukebox presents same choppy stuttery music.

I’ve got and used a multimeter to check the chip connections and only one showed up not connected on the CHA board, so I’ll reflow that.

Should I reflow all the chips on the PROG board and the PCM chip on top and try again?
