20 March 2025
- 20:0520:05, 20 March 2025 diff hist −34 INES Mapper 235 apparently, this document was actually backwards - my own implementation is 0=32/1=16 as well (and I'm pretty sure it dates back to when this document was written) current
10 March 2025
- 16:0616:06, 10 March 2025 diff hist +261 MMC2 →CHR banking: 8x16 sprite conflict current
11 February 2025
- 15:2515:25, 11 February 2025 diff hist +61 CNROM →Mapper 185: we've figured out why this behaved this way
- 12:5012:50, 11 February 2025 diff hist +1 m PPU sprite evaluation →Rendering disable or enable during active scanline: fix link current

- 15:1415:14, 30 January 2025 diff hist 0 m VRC7 pinout assuming this meant "PRG RAM", not "RAM RAM" current
23 January 2025
- 12:5212:52, 23 January 2025 diff hist 0 m MMC5 →Overview: while price was almost certainly a factor, "elaborate" is probably more apt term (and a bit more neutral)
22 January 2025
- 13:5113:51, 22 January 2025 diff hist +4 m User:Asie/Mapper Recommendations nitpick: a UOROM donor board can't handle more than 256KB, and UNROM would cap at 128KB unless you're willing to lift pins and add bodge wires current
21 January 2025
- 17:3617:36, 21 January 2025 diff hist +138 MMC3 →Hardware
15 January 2025
- 14:0014:00, 15 January 2025 diff hist +136 m Init code explain why X is still 0, and initialize zero page with $00,X just in case you're using an assembler that emits absolute addresses when it's more than 2 digits (don't know if there are any, but there might be) current
- 02:5302:53, 15 January 2025 diff hist +230 Init code add notes - you need to zero $2000/$2001 for compatibility with toploaders, and you need to wait 2 frames for compatibility with frontloaders
15 October 2024
- 21:3921:39, 15 October 2024 diff hist +50 m PPU registers important note - bit 14 actually exists as the upper Y scroll bit, but the first write to $2006 clears it (thus necessitating the "6/5/5/6" trick)

- 15:3315:33, 6 March 2024 diff hist +2 m Visual 2C02 specifically transistor-level, since it doesn't really model things deeper than that current
5 March 2024
- 13:4913:49, 5 March 2024 diff hist −52 PPU palettes "The background palette direct access" sounds wrong. Also, I don't think we need the Visual2C02 reference

- 13:5613:56, 13 December 2023 diff hist +14 m PPU registers →Controller ($2000) > write: reword, otherwise it sounds like it's suggestin writing to $2000 to clear the vblank flag

26 October 2022
- 00:2500:25, 26 October 2022 diff hist +47 m Status flags →Z: Zero: old description could be misinterpreted as "if zero, then set, otherwise leave as-is", so clarify that it's either set OR cleared
24 September 2022
- 12:1012:10, 24 September 2022 diff hist +38 m CopyNES apparently, that version has a bunch of extra fixes that never got merged back into my version current
- 12:0612:06, 24 September 2022 diff hist +80 CopyNES CopyNESW was updated to incorporate USB support from the "Blue" client about 10 years ago

4 September 2022
- 00:1900:19, 4 September 2022 diff hist +104 m PPU rendering →Line-by-line timing: mention PAL CPU/PPU divisor which is different from NTSC and Dendy
3 September 2022
- 03:1003:10, 3 September 2022 diff hist +29 m CPU Test Mode →2A07: it's hard to tell from the die images we have, but if pin 30 is normally grounded then the internal signal would have to be inverted

8 August 2022

- 17:5617:56, 30 July 2022 diff hist +898 VRC7 audio →Debug Mode: Update to match Yuri213212's findings in Discord, and remove sortable flag because it doesn't really work anymore

- 01:2401:24, 28 July 2022 diff hist 0 m VRC7 audio →Debug Mode: would want to hold PPU A13 high when writing registers, otherwise when M2 goes low it'll trigger "Set DAC"
- 01:2301:23, 28 July 2022 diff hist −542 VRC7 audio →Debug Mode: M2 was backwards, and some other details didn't line up with what I've traced in visualvrc7
