You can download it from fearlessrevolution website

Included Cheats

(Invulnerability)
– FIXED (NOTE: after getting hit once, you will become invincible)
Undead (Unable to die)
Disable Timer (Infinite Flight Time)

This is for Steam version of Spyro™ Reignited Trilogy. Might not work for future versions

Same sick burns, same smoldering attitude, now all scaled up in stunning HD, Spyro is back in the Spyro™ Reignited Trilogy! Rekindle the fire with remastered versions of the original three games, Spyro™ the Dragon, Spyro™ 2: Ripto’s Rage! and Spyro™: Year of the Dragon.

Updates:

EDIT: Updated table with Undead option. Basically enemies will be able to hit you, but you won’t die.
EDIT2: Disable Timer cheat added. Some flying levels are almost impossible, and i just couldn’t bother with them.
EDIT3: GodMode fixed, you will be able to break boxes/won’t make some enemies invincible/can use turret cannons on zephyr level/..
Played through entire 1st game with it active. NOTE: Don’t use both GodMode and Undead at the same time!
