# Spyro the Dragon: testing C reconstructions through function hooks

> Spyro the Dragon reconstructs selected PlayStation game functions as readable C for behavioral comparison. The workflow compares compiled instruction counts, places replacement functions in extra RAM and redirects original entry points to test them in PCSX-Redux.

## Requirements & limits

- The documented hook workflow uses extra developer RAM and PCSX-Redux for testing.
- Ghidra, spimdisasm and a modern MIPS compiler are used in the documented workflow.
- The current approach tests hooked functions and does not rebuild the game.
