     17:00  IRQ diffhist +9 Lidnariq talk contribs ($4015 writes to acknowledge the DMC IRQ, as seen in visual2a03. (see t14787))
     05:34  Game bugs diffhist +455 TakuikaNinja talk contribs (Add Super Mario Bros. to the list of games reliant on initial RAM values.)

     08:20  INES Mapper 227 diffhist +218 NewRisingSun talk contribs (Add submapper 2)
     06:38  (Deletion log) [Fiskbit‎ (2×)]
     
06:38 Fiskbit talk contribs deleted page Talk:Reading 2007 during rendering(Deleted together with the associated page with reason: The wiki isn't really the place for data dumps, but rather the conclusions that we draw from that data. Having this massive data trove with little context is more confusing than anything else. The forums are much better for this, so the data previously held here has been moved to the relevant forum posts where the work was being done (posts 62827 and 63103). Quietust's conclusion from the data is that during-rendering accesses do a 1 scan...)

     03:49  CPU power up state diffhist +2,746 TakuikaNinja talk contribs (Overhaul the layout and add information on save RAM and best practices.)

03:22 (cur | prev) +175 Fiskbit talk contribs (Converts the "Instruction timings" examples into a table and adds a STA abs,X example.)
     
01:33 (cur | prev) −12 Fiskbit talk contribs (Converts the "Short delays" instruction list to a sortable table.)

2 June 2024

     12:32  Cycle counting diffhist 0 Fiskbit talk contribs (→‎Short delays: Corrects NOP NOP NOP byte count. (Thanks to Gros chien for reporting.))
     07:30  Status flags diffhist +305 Fiskbit talk contribs (Clarifies some I flag points. Removes irrelevant I flag information from the B flag table. Removes unnecessary / prefixes from IRQ and NMI (we're talking about the interrupts, not the signals). Further explains B flag usage.)

     09:39  Status flags‎‎ 2 changes history +200 [Fiskbit‎ (2×)]
     
09:39 (cur | prev) +54 Fiskbit talk contribs (Minor clarifications and additional detail.)
     
08:41 (cur | prev) +146 Fiskbit talk contribs (→‎I: Interrupt Disable: Clarifies that this only inhibits IRQ interrupts. Notes that all types of interrupt (NMI and reset, not just IRQ) set I. Clarifies that the immediate handling of an IRQ after clearing I may have a 1 instruction delay for some causes.)

28 May 2024

     17:48  Famicom Network System diffhist +1,141 Ben Boldt talk contribs (- Updated naming of CIC signals. Verified $40C0 bits 7, 1, and 0 were listed correctly.)

     14:33  PPU registers‎‎ 2 changes history +67 [Tepples‎; Fiskbit‎]
     
14:33 (cur | prev) −20 Fiskbit talk contribs (→‎Data ($2007) read/write: Removes a link to the "Reading 2007 during rendering" because this page is impenetrable to most the people who will be reading this. Cleans up the PPU scrolling link.)
     
14:29 (cur | prev) +87 Tepples talk contribs (→‎Data ($2007) read/write: link to a more useful article about the scroll position effect)
     13:44  PPU scrolling diffhist 0 Fiskbit talk contribs (Moves $2007 behavior up with the other registers, because it was easy to miss. Removes some weird indentation. Adds some horizontal lines to help break things up a bit. (This page needs some more involved improvements in the future.))

00:24 (cur | prev) +101 Ben Boldt talk contribs (→‎System Overview: Added info about CPU R/W being buffered similar to the data bus, and how that is affected by CIC failure and the lid switch.)
