Is anybody else having issues trying to play NSF files on a Powerpak with the AVS?
The Powerpak was updated in the following manner: v1.34 official -> Loopy -> Power Mappers. I've tested with only the official mappers installed as well, with no avail. 
The AVS, I've tested with the firmwares: 1.10, & 1.20 betas 5 & 6. 
On the AVS upon selecting an NSF file, the "NFS file loading" screen shows up, then cuts away with an audible click to a black screen. The AVS menu then won't be accessable using the controller shortcut, and I must reset the AVS to get anything to change. 
The same powerpak plays NSF files perfectly on my frontloader, leading me to believe that something is causing the AVS to crash and become unresponsive. 

Kevtris came across this when he did his reverse engineer videos. There seems to be an issue with the NSF player functionality on the AVS for now.

Hmm, must've missed that, thanks!
