FDS fixes #309

Closed paulb-nl closed 2 years ago

paulb-nl commented 2 years ago

Implemented disk transfers with disk IRQ. Fixes games like Super Lode Runner which use their own disk functions instead of the FDS bios.

Some games expect to read a value like $42 instead of $02 from $4032 due to the open bus bits.

For some reason this update made it so the blank FDS disk boot to FDS bios method no longer has sound on boot.
