Bytecode Hell

In light of my obsession with bytecode formats, here's a list of formats i've reversed/implemented

  • TFX Expression Bytecode: Reversed + implemented
    • The expression bytecode that powers the rendering pipeline of the Tiger engine, used in Destiny 1 + 2
  • Unnamed Tiger Engine Bytecode: Currently reversing
    • Similar to TFX expressions, but for other, currently unknown purposes
  • JVM Bytecode: Implemented (HSJVM)
  • Gamemaker VM Bytecode: Implemented (Valkyrie)
