  1. In this beta, the debug mode code is present, but for some reason the code to transform sonic into an object has been removed. Restoring it is pretty simple however:

    1) Go to $16056 and overwrite the bytes there with
    Code (Text):
    1. 4EF900100000
    2) At the end of the ROM (I.e. $100000), insert
    Code (Text):
    1. 4A78FFFA671408380004F605670C31FC0001FE084238F7CC4E754A38F7CC660631F8F604F6024EF9

    Weird. I was using the Hidden Palace Save and I placed a Ficky Prison with Debug. I stepped on it and the explosion killed me!? Oh yeah, this is probably well known (Hell, why say probably?) but when you die, the camers scrolls down to the very bottom of the screen with you. SEGA robably took that out because it was a real time-waster. NOTE: I don't make alot of posts cause' im Pending...

    I've noticed the invincibility Stars are the same as the ones in Wai's prototype. They aren't as big as the final ones.

    I placed a flicky container and it ended the level as per normal and took me to HPZ 2. Interesting that in Debug all the objects are still ok and not the Glitched OOZ ones like in S2 Final.... looks as if they had just about pulled the zone. This also appears to be the proto AFTER the Sega Solid Gold Guide and its possibly the same one used in a French Proto video with the same title screen with the 1 Player and 2 Player selections (this video didnt show Hidden Palace Zone)..

    Wow. Didn't know it was worked on this much after the Beta. Tube goes somewhere now.

    This is awsome work Esrael, thanks. :psyduck:

    If you hold right while starting HPZ Act 2, you land on something. Can anyone figure out some sort of layout from the collision data?

    Heh, knew the layout was familiar. :P

    I kinda realized that when I saw what was on the other side of the tube.

    Because it'd have been very creepy if HPZ just happened to be worked on and had Esrael's Delta HPZ layout 16 years ago. =P

    Great, thanks to Esrael's Save State, I can explore this beta even more throrouly. Could there possibly be a way to Port the WZ from Sonic 2 Delta into a Save State for S2B 4?

    A house in the middle of nowhere.
    Not another Sonic 2 Hack
    It's impossible to clear the 4th special stage without cheating, they only give you 42 rings in the first third of the stage, and it requires 45 to pass.

    Tails was able to destroy that grey statue thingy in ARZ and got the collision glitch:

    Ah I already missed the fun of fixing relative branches by hand =P

    Anyhow, it turns out super sonic is not all that finished as I thought. Here's how to restore it:

    Go to $16AB8, and type there:

    Code (Text):
    1. 4EF900100000
    Then, add this at $100000:

    Code (Text):
    1. 4A28003C672C323CFC000828000600226704323CFE00B26800126F0E1038F6020200007066043141
    2. 00124A28001267184E754A280039660E0C68F04000126C06317CF04000124E754A38FE1966160C380
    3. 007FFB0660E0C780032FE2065064EF90001082A4E75
    For the curious, this replaces the subroutine that controls the speed cap of the jump. The difference with the original code is that in this one the branch to check and trigger the transformation is present. Note that I added the 50 rings and 7 emeralds check myself; which doesn't mean that this is how the transformation was supossed to be triggered in this build. I used FFB0 because this one is used as opposed to FFB1 in later builds.

    Then, use this PAR code for the emeralds:

    FFFFB0:0007

    Get 50 rings, and jump as usual.

    Nearly nothing super sonic related is coded in the object, which translates in:
    - You can be hit and lose rings as usual
    - The ring counter doesn't drop
    - 0 rings doesn't make you go back to the normal form. There's nothing to trigger the detransformation - althought the code for this is also there.

    However, other things such as fixing the speed for the super form whenever it changes ARE present in the character object, so we can assume it was half-implemented in this build.

    I'm still unsure about the code not beginning triggered at all without hacking though. It might be called with a different event in this build, but I have yet to find it.

    More info as I find it.

    Edit 1: The code was written to be called externally, so it was definitively triggered with something else. I believe it could be a removed monitor, but I can't say this for sure yet.

    The lasers in WFZ don't make any noise, probably because their sound bytes were not made during this build of the game.

    "Night Time" mode is still accessible by holding C when a level is starting. So this will be good for distinguishing if Plane A and Plane B objects are different in this version than the final for most levels.

    No-one seems to have mentioned it, but it's in the above special stage screenshots - Tails is refered to as Miles everywhere (and up as far as at least Beta 8, I think) by default still.
