HPMAN has suggested an option for the NGFX SoundBuilder to use the full address space of the YM2610 (16MB ADPCM-A + 16MB ADPCM-B). At the moment there is no way to run this on real hardware (because no commercial game or flashcard supports this) but a test with NeoSD has shown that the theory is correct, NoPCM 8MB+8MB works without any problem. MAME can use the full 32MB.

So show me a feasible way how to run this on real hardware and I will enable this option!
