Well only fair i post the code changes here for Mustache Boy and Darkmist as it wasn't mine to begin with. Both games have a 100%
sound now and i've managed to get the coin hack to work in mustache boy while using the newer IRQ code. Also updated the
coin hack in darkmist in order to add more dipswitch options.
Code is based on MAME112 reworked for MAME84 and fully tested
