// This is quite interesting bug. Game take advantage of VU memory wrapping.
// All that work fine in pcsx2, excluding one BAL that always hit 0x3ff0. This is no issue per se,
// but due to way pcsx2 work this caused ton of unnecessary caching, and killed performance.
// Patch replace dmove a1, zero with li a1, 2. This simple trick make branch directly to 0x0 instead of 0x3ff0.
// To be honest it was new for me that VU support something like memory wrapping at all. Since all addresses created by that runtime always have -0x10 offset, adding 2 make them hit precisely what should be hit. This don't have any bad side effect.
