-Super Mario Land 2 - Pops in menu are fixed by immediately updating APU output after a write
-Perfect Dark - Low voice volume is fixed by having the correct output when the channels are disabled (but DAC is still enabled)
-Daiku no Gen - Low voice volume is fixed by keeping square channel output to digital 0 (= analog 1) until its first tick after being enabled (the game does not let the channel tick at all while the voice sample is playing)
Super Mario Advance 4 (SMB3) window animation when entering a stage had a glitchy scanline when the window's end position was moved from x=255 to x=239 during hblank, because ProcessWindow was not getting called when the window X position register was changed
-Output is a 12-bit value and should wrap
-"Magnitude"/"step size" should be reset to 0 when playback starts
This fixes sound effects in NEXZR that were broken by the previous (incorrect) fix and also broken because _magnitude was not being reset to 0 when each sample started playing
+ Fixed VRAM read to wait until next available CPU access slot
+ Fixed NMI triggering on the wrong scanline on SMS
+ Fixed NMI issues on ColecoVision
+ Fixed random ram option not working properly on SG-1000
+ Added "Mem access" tab to tilemap viewer to see fetch patterns
Wave channel was playing the wrong audio on the title screen, because some writes were being blocked.
It looks like the restriction on wave "ram" access that exists on GB don't exist on GBA
Additionally, it seems like the wave data is supposed to be stored in a large shift register (not emulated yet), rather than an array of bytes
-Labels defined within the assembler that were referred to before their definition did not work properly and ended up being assigned the wrong value (when the label's address wasn't a value between 0x100 and 0xFFFF) - this is fixed by running multiple passes until the resulting byte code stops changing.
-Fixed issues where e.g EOR $00, Y would be assembled as a 2-byte instruction, which is invalid.
Save ram is not mirrored across the entire 8kb, can only be accessed in the first 2kb
This fixes Death Bringer corrupting save ram when trying to start a new game
If the number of rows and columns did not result in an amount of bytes that was a power of 2, the viewer would incorrectly repeat some tiles, etc.
This was broken by performance fixes done a few months ago
