SADX- Chao Stadium?! WHAT THE FUDGE?!?!

While I was looking around Google Images for a new site avatar, I came across the Sonic Retro Forums. Check out what these guys uploaded!!

They found this strange item in the SADX Prototype, by using a Debug Menu.

Apparently, they didn't translate this. By looking more into the topic posts, the sentence says:
"Chao Card...
Proof of Chao Stadium Membership."
And someone on the forum added THIS:

So, does this mean SADX was going to have a Chao Karate - type area?
And why would they remove it?

the door is from sonic adventure for the dreamcast
the card was probably an early idea and then dropped

Reason: Why would it drop? It would've been a great idea.

yeah it would be a great idea! (take this as a prize )

O_o wow that would be awesome! maybe they had time production issues...
(as usual -_-)

propably

That would probably be it. But maybe it dropped because the Chao Racing was at a point part of the stadium, and already in the Chao Garden?

i personaly hated karate.

It's okay, but difficult to pass the Super difficulty.

Yeah, I never really cared for it on SAB2

Wow wow wow wow wait, Omochao in SA? No way. And that's a very different area for the game..

Well, cancelled is cancelled.

*Sigh* Well, I guess.

old news is old, this has been known for a while
it's a card that unlocked the chao race, kinda like how the kart pass opened the bumper car race for other characters
this was just one of the things that was left on sa1 (and, as alot of things, forgot to take out of sadx)
and yes, omochao was in sa1, just never used much, plus, the room in the last picture is the back of the chao race room, and is the same in sadx, only now you can't roam around and look at stuff, play sa1 to see what i mean
