• curprev 10:2510:25, 18 March 2024‎ Fiskbit talk contribs‎ m 3,785 bytes +43‎ Fixes two references to the now-removed "cartridge space". Clarifies that the vectors in the unmapped space are supplied by the cartridge.
• curprev 09:1809:18, 18 March 2024‎ Fiskbit talk contribs‎ 3,742 bytes +147‎ Clarifies that the "cartridge space" is really unmapped space cartridges can use. Adds the extremely common cartridge RAM and ROM mapping to the table to avoid users thinking ROM starts at $4020.

• curprev 21:4221:42, 26 February 2024‎ Tepples talk contribs‎ 3,595 bytes +206‎ init code needs more inbound links. Add links from the vectors list.

20 September 2023

• curprev 16:5216:52, 20 September 2023‎ Rainwarrior talk contribs‎ 3,389 bytes +34‎ clarify that both WRAM and PRG-RAM are common terms for the memory at $6000
• curprev 16:3816:38, 20 September 2023‎ Rainwarrior talk contribs‎ 3,355 bytes +7‎ list WRAM as common acronym for $6000 work RAM

16 April 2023

• curprev 23:0323:03, 16 April 2023‎ Fiskbit talk contribs‎ 3,348 bytes +1,582‎ More address space details and caveats. Clearer formatting.

• curprev 22:5222:52, 30 November 2019‎ Tepples talk contribs‎ 1,641 bytes +242‎ GEMISIS on Discord wondered why this doesn't mention the stack being at page $01. Word it so as to lead into Sample RAM map.

• curprev 18:0318:03, 8 July 2016‎ Rainwarrior talk contribs‎ 1,399 bytes +13‎ linking CPU Test Mode, changing wording (discarded doesn't seem right, they do exist, don't they?)
• curprev 12:3112:31, 8 July 2016‎ Tepples talk contribs‎ 1,386 bytes +92‎ This is as short as I can make the explanation of $4018-$401F, per http://forums.nesdev.com/viewtopic.php?f=9&t=14421

28 May 2015

• curprev 20:1820:18, 28 May 2015‎ Myask talk contribs‎ 1,294 bytes +106‎ A mapper could switch just the vectors, but it would be very unusual. Do any?
• curprev 18:3318:33, 28 May 2015‎ Rainwarrior talk contribs‎ m 1,188 bytes −19‎ folding iNES mappers into first clause, replacing nor with or (atypical in this context)
• curprev 11:3711:37, 28 May 2015‎ Bregalad talk contribs‎ m 1,207 bytes −20‎ vectors starts at $fffa, not at $c000, it does not have to be the last bank, just any known
• curprev 07:5207:52, 28 May 2015‎ Bregalad talk contribs‎ 1,227 bytes −76‎ Technically, a mapper *could* switch the vectors alone. Also, the vectors are parts of "usual ROM"

21 April 2015

• curprev 07:3907:39, 21 April 2015‎ Myask talk contribs‎ 1,303 bytes +63‎ Changing to range-and-size to match PPU memory map, esp. with note using ranges; changed grammar.

20 July 2012

• curprev 22:1522:15, 20 July 2012‎ Tepples talk contribs‎ 1,124 bytes +166‎ Don't give the idea that the vectors are some separate area of memory, just data at the end of cart space
• curprev 07:5207:52, 20 July 2012‎ Hamtaro126 talk contribs‎ 958 bytes +420‎ Major revision to include better mapping, and more!
