Well it looks like SM was able to get my trick to work, as he got 15 seconds in casinopolis as Sonic
also, I still have that crazy Twinkle Circuit Shortcut. I'm too lazy to describe it in detail, so I'll post the short clip. I'd like to hear how SM got through the barrier though. I can see if it's related to my method.
http://media.putfile.com/TwinkleCircuitshortcuthttp://media.putfile.com/TCthingyIt's one of the two, or both. Just guessing by file name
EDIT: I got a little time, so I'll briefly explain my strat.
Goto to the hallway leading to the vault. Ya know...with the two big spinning sonic coins? Near the doors leading to the vault is a hole in the cieling. It's actually part of a vent that knuckles can fall through to escape through an upper room when emerald hunting. The wall in the vent is fake though, so you can go through it
But how do you get all the way up there as sonic?
see the platforms the coins are supported on? It curves upward, and towards the direction of the vent. So you can spindash off that and gain enough height to just make it into the vent, and through the fake wall
What good does that do though? It would be useless, since you'd just fall into the vault room. several things have happened to me though when going through the vent
1. end up invault room
2. end up on corner (outer edge) of vault room. Basically, I was able to pass the cieling barrier, but there's another one that prevents you from standing straight on the platform with the eggman thingy. I've been able to get right next to it, but an invisible wall just prevents me from jumping ontop of it
3. Die
4. Game freezes up
5. Land on an invisible platform. yup. There's a small invisible platform up there somewhere near the corner of the cieling of the hallway. Hard to aim for, but it's possible to land. I was hoping that from here. once on top of here, you are outside of the level, or out of bounds. I was hoping that I could spindash around the vault room, and from behind the invisible wall in #2, and just land on the platform, but apparently, the wall extends outside as well!
so that's where my progress basically stopped. The only possible way I could see this being bypassed (for SADX) is perhaps by falling from above, and into the vault room's upper platform, ratherthen spindashing up to it from around the side.
Was this wall removed SM, or is there another alternative to this?
