Program for Running Games on Simulators OS for Console Emulation
You're looking for an emulation setup that fits your needs on a Mac. Since you want GBA games, Metal Slug titles, and classic titles like Spyro and Crash, you'll likely need a lightweight OS. Bootcamp is a good option if you prefer control, while OSX might be more stable but heavier. Windows could work too, but it's less ideal for this kind of emulation. Consider what balance you want between ease and performance.
There are likely emulators available for macOS. GBA emulators work well, but the PS1 is more challenging.
