  + Don't have a complete list of instructions affected by T flag. Currently warns if SET precedes an unrecognized instruction.
  + Audio volumes are probably wrong.
  + LFO is not implemented, though I can't tell.
- + Screen is too tall on several games. Obv resolution calculation is not 100% correct. 
+ + Screen resolution is an ongoing issue. Some games appear to show garbage beyond what it supposed to be visible.
+   Most emulators simply crop the screen at a certain vertical range. For now, I have chosen not to do this.
+   Right now the emulator is simply displaying a framebuffer. Eventually, we will do an update that emulates NTSC.
+   But for now we're letting this be. There's no intermediate step between emulating a framebuffer and emulating a TV.
 
-Aero Blaster      - Bottom of Screen extends too many lines - like 3 extra or so
 Air Zonk          - Fully playable, doesn't freeze, but some gfx/timing issues

 Lode Runner       - Freezes in new game 
 Madoo Granzort    - Graphics issues because SGX VPC renderer is not using new frame timing
-Metal Stoker      - Tearing when scrolling vertically at bottom of screen - screen too tall?
 MML Demo          - Echo channels are too loud (equal volume!)
 Outrun            - Raster issues, music slows when paused
