Hi! Does the current revision decode one of the 8bit ports, like 0E0h i suggested? I'd be keen on creating a new pack of patches that works on 0E0h. I also don't mind creating an additional pack for the OUT 0C0h method, provided that there's already a TSR that hooks the interrupt, so i can test everything.

Mind you there is no "current revision". Dreamblaster has indicated they have little time to make a new batch, and though we're all cheering them on, there's no guarantee there will ever be a new ISA card with this sound chip. I'm not sure what the "old" revision decoded. C0 should be safe for PC/XT class machines (AT has DMA2 there), E0 could be safe.
