Hard mode: Try to figure out what it does.

>>58
Kind of hard to do that without knowing the syntax and semantics.

>>59
Anyone who can't figure out what mov does shouldn't be posting here anyway.

>>60
Of course that's clear, but it's not like mov is everything there is to it. I'll start giving examples:
unk.r0
Which r0, what's the significance? Is it the same as r0 or different?
setnl
If I had to guess, it sets SOMETHING(the first operand??) to a TRUE or FALSE value (0,1?) if the first operand is not lower than the second one (immediate value).
lor
What is the difference between or and lor? Is LOR logical OR? The semantics are obviously not clear.
jp/jpz
Some kind of conditional jump, probably depending on a flag? If zero, if parity set? what? Again, unclear semantics.
mov r0, r0
mov r2, r2
Nops?

Also, labels don't point to any of the given code (jump and gosub labels)
gosub
I'm assuming it's some form of call, probably places the return value on a stack and jumps to that address.

So even if I can guess what some instructions MAY mean, without proper documentation (or in this case, the original executable which interprets these instructions, as Cudder is probably reversing some game's bytecode), it's not possible to properly interpret these instructions, unless you want me to give a dumb unoptimized asm->C conversion, but those are dumb and pointless (Reverse engineering something is supposed to give a meaning to the code, not translate mov a,b into a = b; ).
