1) Movie Cleanup
- Movie recording and playback are now well-defined classes.
- Infrastructure is in place to enable lazy-loading from a fm2 file
(if need be).
- File I/O is not handled in main anymore AT ALL
2) Reorg Memory Management
I changed the ROM class to be a zero-allocation wrapper around
existing memory, essentially just there to bound check raw ROM, and
to wrap it in a Memory interface.
I also reintroduced the Cartridge class, since in hindsight,
deleting it completely was overkill, and that it's actually a
useful memory-management construct. It owns both the ROM_File and
the Mapper, and frees them automatically.
The only real difference between the new Cartridge class and the
old one is that now, instead of being the entire class being
passed to the nes subsystem, one simply uses a getter to retrieve
the Mapper, (the important bit) to pass that to the NES.
this isn't going well.
i've decided to forget accuracy for the moment, and to focus on
just getting the damn thing working with simple stuff, like the
Zelda title-screen demo, or Donkey Kong.
But fuck me man, this shit is complicated.
I'm going to bed now, and hopefully, next time I work on this,
i'll be able to get sprite rendering working properly.
hell, maybe i'll just scrap that, and instead focus on rendering
the background properly. I have a feeling that's going to be
a bit easier...
Right now, I really want to give up, and call it quits on this
project, because holy crap am I getting annoyed.
But then I remember that one day soon, everything is going to
work, and all this effort will have been worth it.
I hope that day comes soon.
I wasn't planning on reworking interrupts today, but one thing led
to another, and... yeah.
All I really wanted to do today was get a Palette Table debug view,
but for some reason, it isn't being populated! I had a suspicion
that maybe implementing interrupts would make something click, but
alas, interrupts are in, and no data is being written to the
palette tables :(
I'm just going to leave it be for now, and hope that as more of the
PPU comes together, it will just start working.
