Talk:INES Mapper 183

Suikan Pipe is supposedly a port of Gimmick! to the VRC4. q.v. http://www.emu-land.net/forum/index.php?topic=67514.0 (in russian). What's really going on here? —Lidnariq (talk) 05:15, 25 April 2015 (MDT)

This description should be removed as it is inaccurate and misleading. Correct description is just "VRC4e + additional latch (latches A3..A0) at $6000-$7fff controlling PRG bank at $6000-$7fff", as stated here: https://www.nesdev.org/wiki/Gimmick_VRC4_Hack

The page you linked to specifically says that it is not about mapper 183. The linked page's version does not use the x800 registers for PRG control. NewRisingSun (talk) 10:59, 1 May 2023 (UTC)

Dump of the "VRC4e" catridge is identical to the dump of 183 mapper. Game indeed writes to $x800 registers, but the mask is $F00C, not $F80C, so the 11th bit should be ignored. There is no extra register at $a000 for controlling $c000-$dfff PRG bank, this bank is wired to -2 (why anyone ever thought of existence of this reg? game never writes to $a000). Furthermore, looks like game also never read/executes any code from $c000-$dfff so that's why current mapper implementation of m183 does not break the gameplay) Krzysiobal (talk) 13:57, 1 May 2023 (UTC)
