Sonic 2 Alpha
« on: November 09, 2006, 12:54:53 am »
http://www.hidden-palace.org/?news/c/9

Yesterday a Sonic the Hedgehog hacker purchased a prototype Sonic 2 cart for $1500 (you could buy 2 PS3s with that kinda dough), and dumped it to rom format.

If anyone here has or has seen screenshots of the well-known Sonic 2 Beta, let me tell you that this is a MUCH earlier version. This cart still has S1's Green Hill Zone on it. XD

The music is Sonic 1's, and only a few S2 levels are on it (Chemical Plant (labeled Marble Zone), Hidden Palace (labeled Spring Yard Zone), Emerald Hill (labeled Star Light Zone), and Hill Top (labeled Scrap Brain Zone)). All zones have leftover Sonic 1 music, "Labyrinth Zone" doesn't work, and Green Hill Zone works but is glitched. In addition the "Stage 3"s of all but Green Hill don't exist (Sonic 2 zones have two stages)

Final Zone is a glitched version of Hill Top that freezes if you go too far.

This may be old, but for anyone who tried playing through GHZ and realized it's glitched as all hell, you can restore the collision data (for GHZ ONLY - all other levels will mess up) with these 10 Game Genie codes:

AA1A-CEAL
AA1A-CEFT
AA2A-CEB0
AA2A-CEB6
AA0T-CAG6
AA1A-CAEC
AA1T-CAA2
AA1T-CAF8
AA2A-CADJ
AA2A-CADR

And here's a Gens patch for convenience (rename to be the same as your ROM's name).

Hidden Palace Zone is in Sonic and Knuckles.

There's a much cooler version of Hidden Palace Zone in Sonic 2 Beta and Alpha though.

It's not the same HPZ.
