Recovering games from older generations aren’t always the simplest thing to do for a developer, despite what we common people might think of quick and easy remastered editions for current video games machines.

What Toys for Bob was required to do for the just-announced Spyro: Reignited Trilogy is quite a good example of the amount of work a software house has to go through in order to achieve such a splendid result (at least from the trailer and screenshots we’ve seen thus far).

The studio had indeed to develop a specific tool, which was called Spyroscope, in order to recover all the assets from the original three titles by Insomniac Games and convert them into something they could use right away.

“Ultimately, we were also able to leverage many of the original assets such as level models, level collision, animated objects, character models, music, game text, and game sounds,” design director Toby Schadt revealed in a press release.

We’ll need to wait September 21 and see whether this work was faithful enough to the original matter on Xbox One and PlayStation 4. Again, from the first screenshots, it looks like a lot of work was required to be done from scratch, so it’ll be interesting to see if this really happens and to what extent.
