POPCNT, don't think it's our bottleneck if I'm omitting that

No difference for left shift. Right is arithmetic because it copies MSB instead of filling in zeros.

Done. Did you know that in avs+ the hex string was in lowercase?

Done. -1 bug was not present, probably the fix was pulled from classic avs

ReplaceStr exists already in avs+, and I was just about adding a 'case insensitive' parameter. Probably I'll keep your parameter naming.

I'll look at the rest later.
