Thanks to a 15-minute video recorded and uploaded by forum member DinnerSonic, we can now see how this level looks like in its entirety. Using a ripped version of the game and an emulator, he filmed every little bit of the level.
Being a test level, most of it is designed to test out the game’s physics on how Shadow controls on loops, slopes, steps, and half-pipes among other structures. There’s also the odd laser object, mostly due to triggering some flags in Westopolis.
There’s still no video of the other test level, but if you keep an eye on the forum thread, one may just pop up sooner or later.
Before you panic from the repressed memories of the game, bear with me here.
Forum member princeofknaves uploaded an old version of the RenderWare Graphics World Viewer, which could be used to view Sonic Heroes level maps as well as possibly allow moving them to other games like Sonic Adventure DX: Director’s Cut.
But that’s not all. DaGuAr, a user at the Spanish-speaking Sonic Reikai forums, found that this viewer can also view Shadow the Hedgehog’s level maps too. This isn’t surprising since the two games run on very similar engines.
