Sonic Heroes (Mario Kart: Double Dash!! Bonus Disc)
From Sonic Retro
It was only after I renamed this page last night that I realised that it should probably be called "Sonic Heroes: Trial Version" (or "Sonic Heroes: Trial Version (Mario Kart: Double Dash!! Bonus Disc)")
However,
I think there's demos we're not covering - there's one on the UK's Official PS2 magazine (issue 46) and I'd be surprised if there wasn't an Xbox one somewhere - what are they called?
p.s. I'm not convinced with the naming of any of these prereleases - [[Sonic Heroes (Xbox review prototype)] also has a PC screenshot? -Black Squirrel (talk) 11:54, 11 September 2018 (CDT)
