31 August 2024

• curprev 09:2109:21, 31 August 2024‎ Fiskbit talk contribs‎ 6,667 bytes +101‎ 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.

• curprev 03:5103:51, 9 October 2023‎ Fiskbit talk contribs‎ 6,513 bytes +1,157‎ Rewrites and modernizes the Famicom EXP port signal descriptions. Adds a / prefix to joypad data lines to indicate inversion. Standardizes (for now) on OUTn formatting for joypad output bits.
