[Wii] Animal Crossing: City Folk (NTSC-U) Pattern corruption?

[m2pt5]

I'm on build r6871 x64 (the latest as of this post), and while the vast majority of the game works fine (except some slowdown, which is to be expected on my rig, and lack of internet) whenever I do anything with my patterns they get corrupted. First it was a string of random colored pixels on the top-left of the pattern, then it was a dot near the bottom-right. I can use Pattview to fix them, but the next time I do anything with them in-game (such as put one on a flag), at a minimum the random colors in the top-left reappear.

Also, the in-game pattern editor is buggy - I have to click a pixel at least twice for it to register, and then I have to hit the undo arrow for the colors to actually appear. (Not as big of an issue, as Pattview lets me edit them outside the game, and use my mouse.)

I'm using the DirectX 9 graphic plugin, and here's my settings:



The only thing I have checked on the second page is "Disable Fog".

Try turning off Enable CPU Access, And Emulate Format changes, Then turning on Normal Accurate Texture Cache?

Just turning on Accurate Texture Cache (Normal) makes the problem go away, but causes the emulation speed to drop to around 50-65%. I suppose I could just do that when I'm messing around with textures.

Thanks.
