- 14:47, 23 June 2022 diff hist +1,933 N Talk:VRC IRQ Created page with "==VRC7== From the decapsulated VRC7 image we have available, I analyzed the implementation of the IRQ counter (with the help of the user SCSR on Discord, who traced the lower layers and allowed me to build a visual chip simulator for it) and have found the following: * The prescaler is actually implemented as 2 separate counters: one 2-bit that counts up to 2 before resetting and one 7-bit that counts up to 112 or 113 before resetting (with the condition <tt>((B0 | A1) &..."

- 20:51, 3 August 2021 diff hist +104 Talk:MMC5 These were for smooth VERTICAL scrolling, and we know how it works. What we don't know is why nobody actually USED it that way...
- 20:44, 3 August 2021 diff hist −22 Talk:MMC5 Laser Invasion uses ExRAM as a nametable, and it accesses it solely via $2007
