Everdrive VRC6 Test Application

I've learned some NES development and decided to build a testing application to verify the resistor used with the NES sound mod.

This is also my first open source project, yeah!

The sound level was evaluated using the emulator nestopia as It seemed to have high hardware compatibility.
Strangely enough I can't find a reliable source of the proper ratio between APU and VCR6 volumes. So all I can do is to rely on nestopia.
FamiTracker for example has exactly the same volume for a maximum level pulse wave of both sound chips.

If everyone out there decides that I'm wrong with this program please don't hesitate and contact me.

Everdrive VRC6 Fix Update

The VRC6 Mapper for the Everdrive N8 was updated to support more volumes.
Download the new package here.

As before the name of the RBF file show the volume. 24Mod_75_70.RBF has 75% of maximum volume on High Setting and 70% at Low Setting.
Please keep in mind that the current version of the Everdrive have the Low Setting removed from the Options menu.
So only the first number is relevant now.

To install this mapper overwrite the 024.RBF file inside EDFC/MAPS with the file of choice.

As always I can't guarantee for proper function and the files are given as is.
I've tested a few of those RBF files but if they do damage your hardware it's your fault for modifying the Everdrive's firmware.
