Trying to load default.xex from a skylanders spyro's adventure dev build and sideload pdb info, same way as the 2nd video tutorial.

This XEX is:

Devkit
Uncompressed
Encrypted
Title Module
Uses Game Voice Channel

meanwhile the one from #13 is as so:

Devkit
Compressed
Encrypted
Title Module
Uses Game Voice Channel
PII

It’s possible something went wrong when it was dumped so I’ll ask the person who originally dumped the game to redump the pdb specifically. Thank you for checking anyways
