14 April 2021

• 15:1315:13, 14 April 2021 diff hist +69‎ m Emulator tests ‎ Clarify why my emulator was used for the "known good" log - kevtris used it when he was writing the test, and its debug output is also reasonably detailed

• 02:3802:38, 7 April 2021 diff hist +2‎ m PPU scrolling ‎ →‎Register controls: Also change "=" to "<-" to more clearly express that the values are being transferred (already updated the others above but missed these two)
• 02:3502:35, 7 April 2021 diff hist +128‎ PPU scrolling ‎ →‎Register controls: Adjust the diagrams for the various writes - order them ABCDEFGH (instead of HGFEDCBA) and mark unused bits. For the H/V updates, label the various bits according to their logical positions rather than their literal locations

• 20:5720:57, 23 March 2021 diff hist +100‎ m PPU pinout ‎ Then again, I suppose it could go either way...
• 20:5620:56, 23 March 2021 diff hist +82‎ PPU pinout ‎ →‎Signal description: A dual-PPU system would have no use for genlock, but if you're using $2000.6 and the EXT pins then you'd absolutely want to keep them perfectly synchronized with each other
• 20:3220:32, 23 March 2021 diff hist −19‎ m PPU pinout ‎ →‎Signal description: siliconpr0n has a top-layer image of an RP2C04-0003, and EXT3 is connected directly to GND inside the chip.

• 02:0402:04, 19 February 2021 diff hist +60‎ VRC7 pinout ‎ Visual analysis confirms that pin 48 *is* derived solely from pins 1 and 2, but it's hard to tell exactly what's going on.

• 16:2016:20, 21 January 2021 diff hist +4‎ m CPU Test Mode ‎ The bottom 5 bits of W$401A don't set the "instant phase" - they set the state of the triangle's Sequencer (i.e. $07 and $18 will result in the same effective output)
• 15:5815:58, 21 January 2021 diff hist +35‎ CPU Test Mode ‎ Setting $401A.7 makes the pulse and noise channels output their current volume (even if disabled via length counter), pauses the triangle channel's counter, and stops DPCM from counting up or down
