Emulator

Game Name?

Mario Kart Wii

Game ID? (right click the game in the game list, Properties, Info tab)

RMCP01

MD5 Hash? (right click the game in the game list, Properties, Verify tab, Verify Integrity button)

(Wiimmfi-patched and I didn't keep the original dump, so MD5 hash is likely irrelevant)

What's the problem? Describe what went wrong.

Using a HD texture pack, "Use custom textures" is checked.
When booting the game with "Prefetch custom textures" activated, the "Loaded 2646 textures" toast show up, but no custom texture is actually displayed ingame (only original ones).
When booting the game without "Prefetch custom textures" on, the "Found 2646 custom textures" toast appears, and custom textures are shown ingame (althrough the game is slower due to prefetching being disabled).

What steps will reproduce the problem?

• Install this texture pack in {data-folder}/Load/Textures/RMC

• Tick "Use custom textures" in Graphics

• Tick "Prefetch custom textures" in Graphics

• Launch RMCP01

• RESULT : While "Loaded 2646 textures" is shown in the top left corner, no custom texture is used ingame. Only original textures.

• Untick "Prefetch custom textures" in Graphics

• Launch RMCP01

• RESULT : Textures are shown correctly.
