Pyon Pyon Kyaruru no Mahjong Biyori // Corruption In Intro On Single RAM Build (10-30-2024~)

[InfernoHabanero]

In the intro to Pyon Pyon Kyaruru no Mahjong Biyori, there a brief moment where the graphics corrupt. This is easy to replicate; all you need to do is let the intro play out and it's guaranteed to show up.

Tested on both the 09/18/2024 single and dual RAM builds with 128MB 2.9 RAM modules.

Fixed with commit d7aee57 on a Dual RAM system.

Yeah I can confirm it's fixed on the dual RAM build. Single RAM build actually has worse glitching though, so this is a two-steps-back-two-steps-forward solution.

I'm going to still keep this open, but with the clarification that this is still a problem with the single RAM build.

The intro is very dependent on the RAM-H access speed. In a single sdram build, RAM-H (and 6 other core memories) is located in ddram, which has low latency. So it is impossible to make the intro work correctly in a single sdram build.
