NSF Driver

On the FamiTracker website, the NSF driver code is distributed separately from the rest of the source code. This is because jsr wanted to license the driver under a more permissive license than GPL 2, but didn't seem to get around doing so.

HertzDevil erroneously licensed the modified 0CC-FamiTracker NSF driver code under GPL v2, which restricts anyone sharing compiled NSFs and binaries without sharing the assembly source.

Therefore, Dn-FT NSF driver changes are distributed under a separate MIT-0 license, while 0CC FT NSF driver changes are distributed under GPL v2.

The remaining original FT driver code is not under any license.

See the license file for more information.
