I fixed the PAD problem, Thwaite works 100%.
Pacman works, except I have no sound while the sound routine executes.

Thanks for the solution AWJ, I could find a way to emulate it by using the bit 8 of the object data.

Congratulations. Do you have the mouse that came with Mario Paint?

I do not have the mouse for the snes.
Edit: Plus it is a rare object, it could be tried on an emulator?

Using the FCEUX debugger, I found out why PACMAN does not play music:

STA ($F6,X) @ $4000 = #$FF

It writes in the sound port using this direct indexed thing. X is 0 by the way. $4000 is in the direct page at $F6. It must be patched by hand, like adding an asm file containing a custom routine, and calling it from a patch at this address. This cannot be automatic, the address checks would slow everything down.

Edit: doing like Memblers in the NSF player should also work: executing from the WRAM and reading the register values from WRAM @ $4000 to $4015.
