DSPLLE stuff - no real progress, mostly useful as a reference for HLE improvement, Pikmin 1 has sound in intro though (can't be sure if its ok, because its too slow)

LZ flag: original opcodes andf and andcf are swaped. Also "jzr" and "jnz" are swaped but now named 'jlz' and 'jlnz'
As you can see it obtain the same result but now LZ=1 correctly
Added conditional instructions:
conditional names:
NZ -> NOT ZERO
Z -> ZERO
NC -> NOT CARRY
C -> CARRY
LZ -> LOGIC ZERO (only used with andcf-andf instructions?)
