- 03:0503:05, 6 February 2025 diff hist +59 PPU variants →Unofficial: Adds UM6561CF-1 and UM6561F-2 pictures. current
- 03:0403:04, 6 February 2025 diff hist +36 CPU variants →Unofficial: Adds UM6561CF-1. current
- 03:0303:03, 6 February 2025 diff hist 0 m File:NOAC=UM6561CF-1 0028A E6276.jpg Fiskbit moved page File:UM6561CF-1 0028A E6276.jpg to File:NOAC=UM6561CF-1 0028A E6276.jpg without leaving a redirect: This should have NOAC= prefix. current

23 January 2025
- 07:2907:29, 23 January 2025 diff hist +96 Tricky-to-emulate games Fixes the description for Spelunker et al, which was mistakenly discussing the vblank flag in $2002 instead of NMI enable flag in $2000. Clarifies that this is standard CPU interrupt timing and not some kind of special case delay. current
20 January 2025
- 00:5600:56, 20 January 2025 diff hist +40 Nintendo header Clarifies that nametable arrangement is supposed to be 0 (horizontal) if mapper controlled, but is often 1. current
11 January 2025
- 23:5723:57, 11 January 2025 diff hist −5 m PPU variants →RGB: Tweaks the RC2C03 wording a bit to match other chips and not imply the chip is completely identical to the composite 2C02.
- 23:5423:54, 11 January 2025 diff hist +185 PPU variants Adds the RC2C03, courtesy famiac.
- 23:5223:52, 11 January 2025 diff hist 0 m File:PPU=RC2C03 3L4 15.jpg Fiskbit moved page File:RC2C03 3L4 15.jpg to File:PPU=RC2C03 3L4 15.jpg without leaving a redirect: Apparently these are supposed to be prefixed with "PPU=". current
- 23:5223:52, 11 January 2025 diff hist +42 N File:RP2C02 3F4 13.jpg Moved the letterless composite PPU instead of RGB PPU by mistake, so I'm creating a redirect for it. current Tag: New redirect
- 23:5023:50, 11 January 2025 diff hist 0 m File:PPU=RP2C02 3F4 13.jpg Fiskbit moved page File:RP2C02 3F4 13.jpg to File:PPU=RP2C02 3F4 13.jpg without leaving a redirect: Apparently these are supposed to be prefixed with "PPU=". current

18 December 2024
- 17:3417:34, 18 December 2024 diff hist +45 Bus conflict →Emulating bus conflicts: Adds a few notes and cleans up the writing a little bit. current
6 December 2024
- 10:0510:05, 6 December 2024 diff hist +60 m FamicomBox Adds $4020-$5FFF and Pinouts categories. current
9 November 2024
- 21:3421:34, 9 November 2024 diff hist 0 m Template:Infobox iNES mapper Attempts to remove the leading newline from pages using this infobox by moving the prgmax/chrmax errors into the box itself. current
8 November 2024
- 23:5623:56, 8 November 2024 diff hist −1 m MMC1 Moves the board table and revision sections to the bottom of the page so mapper behavior comes first.
1 November 2024
- 13:3113:31, 1 November 2024 diff hist +76 Instruction reference →BIT - Bit Test: Improves the BIT trick explanation and notes that the trick is useful in constrained situations. (I just used it, myself, in timed code to offset the cycle cost of a conditionally-executed INC.)
- 10:4110:41, 1 November 2024 diff hist +135 6502 instructions Adds a link to our instruction reference and deemphasizes the Obelisk link. current
28 October 2024
- 03:0203:02, 28 October 2024 diff hist +16 m Instruction reference Clarifies in the titles that CMP works on A and INC and DEC work on memory.
- 02:5502:55, 28 October 2024 diff hist −3 m Instruction reference →LSR - Logarithmic Shift Right: Fixes typo in instruction name.
- 01:5901:59, 28 October 2024 diff hist 0 m Instruction reference Fixes typo.
- 01:5401:54, 28 October 2024 diff hist +55,504 N Instruction reference Adds a 6502 instruction reference. Everything *should* be correct. An addressing modes page with cycle-by-cycle behavior will be coming later.
24 October 2024
- 22:3622:36, 24 October 2024 diff hist 0 m Status flags Adjusts the anchors so they don't skip the section heading. current
- 19:5219:52, 24 October 2024 diff hist −23 m PPU registers Fixes the anchors; apparently HTML escape codes aren't acceptable. current
- 19:4619:46, 24 October 2024 diff hist +314 m PPU registers Adds anchors for old section names, to unbreak old links.
- 19:2719:27, 24 October 2024 diff hist −31 PPUDATA We should use the concise anchors I've been adding that won't change based on page formatting. current Tag: Redirect target changed
15 October 2024
- 22:3622:36, 15 October 2024 diff hist +12 PPU scrolling →Frequent pitfalls: Notes that PPUCTRL must also be written after using PPUADDR. Only setting PPUSCROLL is a common beginner mistake.
- 22:3422:34, 15 October 2024 diff hist +320 PPU registers →PPUADDR - VRAM address ($2006 write): Adds some more details about the high bit of t being cleared on PPUADDR 2nd write.
- 10:1710:17, 15 October 2024 diff hist 0 m EXP pins NES-21G-CPU-72P wasn't alphabetized right. current
14 October 2024
- 22:1622:16, 14 October 2024 diff hist +1,492 EXP pins Changes the pin notes section to a table. Adds a type column to the pin summary table and makes the table sortable.
- 00:1300:13, 14 October 2024 diff hist +1,623 EXP pins Adds the NES Hub. Also adds port pins to the ENIO pinout.
12 October 2024
- 03:1103:11, 12 October 2024 diff hist +7,709 PPU registers Reformats the page and rewrites most of the description of the $2000, $2001, $2002, and $4014 registers. The other registers still need to be updated. $2006 was slightly touched up, but could probably use more work.
8 October 2024
- 23:5223:52, 8 October 2024 diff hist +248 Expansion Port Sound Module Adds a link to the long write library. Notes EPSM support in mainline Mesen and that the EPSM should be specified in the header via the NES 2.0 console type.
- 08:1708:17, 8 October 2024 diff hist +324 Nintendo header Links to Pino's header script. Makes a few minor improvements to the text.
7 October 2024
- 20:2020:20, 7 October 2024 diff hist +4,372 Super NES Mouse Adds example DPCM-safe code for reading a mouse and NES or SNES controller.
9 September 2024
- 19:0919:09, 9 September 2024 diff hist 0 m PPU variants Fixes some of the converted date months, which were off by one. (A through M excluding I are 1 through 12.)
2 September 2024
- 07:3207:32, 2 September 2024 diff hist −9 m PPU palettes →Palette RAM: Improves the table's backdrop color note a little.
1 September 2024
- 10:5210:52, 1 September 2024 diff hist +10 m PPU variants Adds separators to make the composite heading in-page look less out of place.
- 10:4610:46, 1 September 2024 diff hist +127 PPU variants →NTSC: The laser H PPU had Hi-Def NES issues. I don't believe the specifics were ever publicly discussed, just a vague address bus comment.
- 10:2310:23, 1 September 2024 diff hist −1 m PPU palettes →Palette RAM: Typo and phrasing.
- 10:1410:14, 1 September 2024 diff hist 0 m PPU palettes →Color Value Significance (Hue / Value): Bit index typo.
- 10:0410:04, 1 September 2024 diff hist +4,017 PPU palettes Rewrites memory map and backdrop sections. Adds new memory map table (huge thanks to lidnariq for turning mockup into markup). Touches up Hue/Value bit display. Uses 'backdrop override' terminology for palette direct access, which is what we're generally calling it on Discord.
31 August 2024
- 09:2109:21, 31 August 2024 diff hist +101 Expansion port Changes the Famicom expansion port pinout to use the console port perspective rather than device plug; the signal directions had all been assuming console port. Notes the NES expansion port is keyed and better notes the pinout perspective. current
28 August 2024
- 19:4719:47, 28 August 2024 diff hist +53 Expansion port →Pinout: Adds orientation indicators. These are kind of janky, but the way we indicate this in cartridge connectors doesn't work here because the signal directions are currently reversed.
26 August 2024
- 01:5401:54, 26 August 2024 diff hist +28 N Nametables Redirect to "PPU nametables". current Tag: New redirect
24 August 2024
- 19:3619:36, 24 August 2024 diff hist −11 m SxROM Fixes SFEXPROM nescartdb link.
23 August 2024
- 07:1607:16, 23 August 2024 diff hist +15 Controller reading code →DPCM Safety: Clarifies that more than 1 bit may be deleted (Famicoms delete up to 3). Makes a less-sweeping claim about modern emulators supporting synced reads; for example, puNES currently deletes bits but has bad DMA timings that break sync. current
18 August 2024
- 18:2618:26, 18 August 2024 diff hist +73 MK5060 pinout Early Hong Kong Famicoms did indeed use the MK5060.
18 July 2024
- 21:4521:45, 18 July 2024 diff hist −33 m PPU glitches Undo revision 21971 by Fiskbit (talk). Reason: This minor change was wrong; had a braino. current Tag: Undo
- 21:4221:42, 18 July 2024 diff hist +33 m PPU glitches →PPU open bus Tag: Reverted
