The Legend of Zelda: restoring mic features

by on (#159562)
I've been asking around trying to figure out whether the localization recognizes the Famicom controller 2 microphone.

If not, what Nintendo broke and how feasible fixing it might be. For all I know on the technical side (nothing) this might be as basic as changing the weakness values of Pols Voice. No idea if the relevant code is still present in the game, or whether there'd be enough RAM/ROM free space to put it back.

I can confirm that they took it out in the NES versions when they added the weakness to arrows.

Look for the mic reading routine:
Code:
  LDA $4016
  AND #$04

Or AD 16 40 29 04 in the Japanese FDS-image/ROM (both FDS and cartridge version has it).
