This fixes the crash at Goblin Wall: https://bugs.dolphin-emu.org/issues/9915
A patch (for the US release only) that fixes the game's buffer overrun bug is included as an alternative with lower performance cost. It is disabled by default.
The first call to GXCopyDisp() corrupts game data, but on real hardware it isn't observed thanks to the data cache. Skipping the call works too, preventing a crash on boot.
This patch is enabled by default.
