Resolved [Bug Report] Hot Wheels Velocity Maximum Justice (NTSC-U)
if it crashes with mVU then thats a good thing since it means i can probably debug it and see what data is being sent to mVU to make it crash.
i will try to look into the bug.

its possible though its not a VU problem though but instead some bad data being transferred to VU's.
so even if i fix the mVU crash it probably won't fix the game.

if mVU is just hanging w/o crashing then it might be that VU1 enters a program and never completes. i'll see if this is happening.

hmm okay i tested the game and it looks like it might really be a VU1 emulation problem.

if you guys know how to compile your own builds you can fix it by changing this line in microVU_Misc.h:
static const bool doBranchInDelaySlot = 1; // Set to 1 to enable evil-branches
change it to equal 0 instead of 1; that fixes the hanging in mVU and also totally fixes the graphics.

seems mVU might not be handling the branches in branch delay slot correctly in this case, or maybe it is handling the program-flow correctly but by doing so it breaks the game due to some other problem like a floating point precision bug.

anyways i'll keep this game in mind, but probably won't work on a proper fix for a while since that branches in branch delay slot stuff is pretty messy.

bleh all these games are doing evil things with the VUs if they're improving from this fix xD
if its 3d textures that are broken in Totally Spies it might be GS or GIF related. have you tried if software rendering fixes it?
might take a look at that game when i get the chance just to see.
