- 02:2602:26, 27 March 2025 diff hist +18 m Instruction reference Adds 'unsigned' to BCC/BCS descriptions to try to disambiguate from the (signed) overflow flag. current
- 02:1902:19, 27 March 2025 diff hist +32 Instruction reference Fixes the ADC/SBC notes on BCC/BCS, which were inverted. Also tries to make the language more clear.
26 March 2025
- 12:4312:43, 26 March 2025 diff hist +54 m Instruction reference Links push and pull pseudocode to PHA and PLA to try to make behavior clear without making the pseudocode too verbose by fully spelling out the operations.
28 February 2025
- 06:5106:51, 28 February 2025 diff hist 0 File:Ppu.svg Fiskbit uploaded a new version of File:Ppu.svg current
6 February 2025
- 03:0503:05, 6 February 2025 diff hist +59 PPU variants →Unofficial: Adds UM6561CF-1 and UM6561F-2 pictures.
- 03:0403:04, 6 February 2025 diff hist +36 CPU variants →Unofficial: Adds UM6561CF-1.
- 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.
