c71cac2af5 code comments and partial refactor 
this was supposed to be a huge refactor and optimization, but i lost
motivation halfway through. once commercial games boot i'll probably
come back to this.

671e5a7533 finally implement fifo 
also fixed irqs to allow setting irf even when irqs are disabled.
this bug and the last one were preventing my previous fifo attempts
from working.

5255c6dd72 a mess of things to make the firmware almost work 
timers, crappy fake rom transfers, and other stuff.
remind me at some point to make my code not a trashy mess.

628ba28dcd improve the i/o system 
to allow reading/writing multiple registers at once, and partial
reads/writes that don't start at the LSB. the mask stuff is kinda
weird but it means i don't need an entry in the switch statement
for every single byte of every register, so yeah.

1e2421a146 add barebones switch build 
yeah, i could use the UI from melonDS and NoiES, but that code is a
bit of a mess. i'm thinking of just starting from scratch and
rewriting it. until then though, here's an absolute bare minimum
build so we can see how performance is on the switch.
