How did you implement the JUMP_TOP instruction? You need to jump to the x86_64 instructions that correspond to the given emoji index; did you implement a jump table?
That's pretty cool! I just transliterated the instructions into C macros; but i didn't bother with the jump tables. The nice thing with this approach is that you can mix vm instructions with c code freely; and get gdb support. I needed that because speeding up via C wasnt enough to decode the full URL and I still needed to do additional reversing.
Was your method fast enough to get all three parts of the URL?
