Great news for the GB and GBC fans out there. The audio ICs from each system have been decapped and reverse engineered so that they can be compared. This could lead the way to someone making improvements to the GB and GBC audio parts of the core

Yes, now with these op amp decaps we can implement sound amplification. Hooray.

It's interesting to know why, but the differences have been known for a while now, people generally use the DMG for chiptunes etc... or mod their GBC.

This is only about the analog circuitry which tools like mdfourier already are useful enough to help to find the right filters

The secret filters that we don't know how to use or where to download yet
