It may be true that this SQV edge case only seems to happen when
isRegConst = true, I forgot to account for the possibility that GPR
Constant Analysis could be disabled.
I also just noticed that I goofed with the non-sse shuffling ;/ . The
registers weren't in order.
I totally forgot that LDV handles elements differently than SDV. I added
a fallback to deal with unusual elements and added an alert to notify
that it exists in a particular game. I removed the & 0xF since that's
not needed. My previous change caused Stunt Racer 64 to have audio
issues. It should now be fixed.
I have only seen the edgecase for SQV happen when
IsRegConst(RSPOpC.base) == TRUE. Changing SQV fixed Telefoot / Mia Ham.
I optimized VAND, for games like Kirby64.
Fixing SW allows a lot more games to work. Fixing LW fixes games like
WDC and improves performance somehow. Fixing VMRG fixes certain bugs,
like Kirby 64's intro.
