Surp. Doing my rounds on the Sonic Retro wiki and I noticed we have very limited coverage of Sonic Heroes (Mario Kart: Double Dash!! Bonus Disc). One obvious issue is that the page name doesn't line up with what's rendered on-screen - "Sonic Heroes: Trial Version". I figured it probably should, so I was about to move it when I realised that this is the only Sonic Heroes demo we've got a page for. I could swear there were other discs out there... ...like this one. This is from issue 46 of the UK's official PlayStation 2 magazine, and it's a demo that is, for all intents and purposes, undocumented. It too also calls itself "Sonic Heroes: Trial Version". There's an Xbox demo too (US Official Xbox Magazine #31), and possibly another GameCube one for in-store kiosks, and this is before we take into account all the different regions that had PS2 or Xbox magazines. Are these all essentially the same thing? My gut instinct is that they should all have pages, but I know nothing about any of them. There's a Sonic Riders demo doing its rounds too that we're not covering. These are all stripped-down prototypes so all sorts of interesting things could lie within.
