A program that peers into the PS1 Spyro games' data that converts it to easier viewing for analysis

Spyro-Scope

A project that sparked when looking back at the program created to see the data of the the original trilogy's games as it is being ran in an emulator. The program, called Spyro Scope, was only an in-house made program never released, so I thought it would be cool to recreate it.

This project is an OpenGL-SDL program made with Beef that is used to draw the game's data that are not normally visualized. This program is also being built in hopes of aiding the modding community for Spyro's PS1 games. It can only support the following as of now:

Emulators
No$PSX 2.0
ePSXe 2.0.5 (No VRAM Support)
Bizhawk 2.4.2 (x64)
Mednafen 1.24.3

Games
Spyro the Dragon NTSC U
Spyro: Ripto's Rage NTSC
Spyro: Year of the Dragon NTSC v1.1

Note: The versions shown are only what I have tested so far myself, you can try to use it for other versions, however it may mess up the program or game. You have been warned!

For those new to Github or its new, layout here is the link to Releases

Compiling

Beef IDE is used to compile the project as the language used is beeflang.

The only external library needed is FreeType in order for the program to fully compile. You can get a simple library integration from here where only the essential parts are used for this program. If you want to integrate a fully supported version, it should also work with minor changes.
