FM PCM Player

Well, missing a few samples every once in a while is not a big problem (this happens when it switches mapper slots), however disk loads would introduce audible pops and clicks I think. I haven’t tried but at a minimum a 512-byte sector load would take 2.6 ms not considering overhead, and at 15.7 kHz that means 40 missed samples at the least, that’s quite a lot.

I guess if you would directly access the interface buffer (like I think EVA players do) then maybe you could stream directly. But then you’d have to write interface-specific drivers. And of course ROM does not have loading times. But that’s a bit beyond the scope of the project.

p.s. The current compilation flags support up to 16 MB RAM.
