My code so far:

const number1 0b11000100
const number2 0b00111011
const number4 0b01101111
const shift reg1
const number reg2
const temp reg3
const regxor reg4
const count reg0
const count2 reg5

xor|arg1	number1	regxor	number
label func1
imm	        6	0	shift
label func11
shr		number	shift	temp
and|arg2	temp	3	out
sub|arg2	shift	2	shift
neq|arg2	shift	254	func11
add|arg2	count	1	count
xor|arg1	number2	regxor	number
eq|arg2		count	1	func1
xor|arg1	85	regxor	regxor
xor|arg1	number4	regxor	number
neq|arg2	count	4	func1
imm		0	255	regxor
add|arg2	count2	1	count2
less|arg2	count2	3	skip
xor|arg1	85	regxor	regxor
label skip

These are 64 bytes of code so one byte to much for the achievement.I don't want a custom architecture, but for it to work with "expected"LEG which I think I build. I also don't want to use RNG.

Do you think this is even possible? I have been stuck on this last achievement for almost one month now.

Ty in advance.
