    When I ported the motobug to S2 Final, this error didn't show up.

    I mean if you place the motobug Off-Screen like this motobug is placed in Sonic 1 will cause this bug in Sonic 2. Open Sonic 1 J.epr in Esrael Assembly Editor (Sonic Series Level Editor) My Sonic 1 J disassembly to see where this motobug is placed in Sonic 1.
     
  4. ffff. I really hate the double spike 'feature'. Also, tails floats if he's standing on the level end capsule and you break it.

    Oo er, this is quite an interesting hack. Green AND Emerald hill, the ability to play as Knuckles and tails (I presume a hack has done this before but it's the first time I've played on with the option). The Winter Hill is a rather dull level layout though, too many steps everywhere. Dust Hill is brutal! Also hate the double spike thing, they took it out of Sonic 1 for a reason. :P
    Still, a lot of neat little features in there.

    Just one question: does it get stuck at the title of casino night act 1 because it's unfinished?

    - See saw detection fixed for Tails in Star Light

    ok, I've tried this on Gens and DGen, but the only emulator that seems to like it is Kega Fusion, a few bugs here and there, but once again I'm impressed with your work Esrael, good job!

    It doesn't work on any other emulator because Kega is the best. At least on accuracy.

    But nice job Esrael! As said above, there are glitches, but more noticiable ones. So I think the next release won't have any big glitches.

    Wow, I didn't know this was still being worked, although of the bugs I heard of, this should be fun. ;)

    Green Hill Zone:

    - Collapsing ledges don't respawn (I think they're supposed to).

    Marble Zone:

    - Tails (in Sonic and Tails/Knuckles and Tails mode) falls through all objects, excluding anything that can be bounced off (enemies, blocks like those in Chemical Plant).

    Labyrinth Zone:

    - Ceiling spikes are harmless.

    Scrap Brain 2:

    - All wheels after the first you need to hold left on, or else you'll get tossed off for going too fast.
    - Transport tubes don't work.

    Final Zone:

    - Boss has wonky hitbox. Can't attack reactively.

    Winter Hill:

    - Boss has wonky hitbox (still). Doesn't apply to Marble Zone's boss.

    General:

    - At times, you lose the ability to gain speed on land or control momentum in the water.

    I think this happens when Tails falls in the water while Sonic is above the water. This behaviour was in some of the prototypes too, if I recall correctly.

    Fixes:

    - Collapsing platforms in Green Hill now respawn.
    - Tails detection fixed for swing platforms (GHz / Mz / SLz / SBz) and platforms.
    - Ceiling Spikes in Labyrinth fixed.
    - Platforms on conveyor belt in Labyrinth Tails detection fixed.
    - Teleports in SBz 2 now works (Subtype 07 (Secret path) only will work if you had 50 or more rings);
    - Conveyor Belts Tails detection fixed.
    - Final Boss Hit now works when playing alone.
    - Others fixes.

    - About Winter Hill Boss. This boss can be hited when he is in center of screen (above Lava).

    Know bugs:
    - For some unknown reason Marble Zone 3 only load in real hardware after some presses of "C" key. In emulator this does not occur.

    ok, only one thing I found wrong and that's the Debug objects are incorrect in the S1 Special stage, appart from that, Fookin sweet S2 special stage!! It's nice to have it different for a change and cool selective colors too, Failed the SS 3 times in a row though XD

    EDIT: also just noticed the S2 SS results screen seems to scramble.

    Cool work, but at the title screen the centisecond timer is replaced with the unused spring monitor for a second and the increased tempo speed doesn't stop if you clear the act (ie: music will be fast in the next act unless you do something such as killing yourself).

    Question? How many versions are there going to be of .24? Isn't this like .24-7 or something?
