# Evo's Space Adventures PSX: matching decompilation of Evo's Space Adventure

> Evo's Space Adventures PSX decompiles the PlayStation game Evo's Space Adventure from an owner-supplied esa.dat executable. Its build extracts and disassembles the executable, then uses GCC, GNU as and maspsx to produce a matching binary; the work is presented as a proof of concept.
