    As a quick project for the contest, I've ported Pink Edition's Big over to Sonic 1:

    Controls:
    * Lure Attack: Hold A to aim lure, the longer you hold the further it will throw.
    * Body Slam: Press B or C while jumping to slam down on anything under you.
    * Swim: Big will automatically float in water. Hold Down to sink.
    * Big can also smash walls just by running through them.

    In addition, Froggy is hidden in every act besides Final Zone. Try and find him.

    Bugs:
    * Title font appears behind Big due to some animation priority tricks.
    * Some possible situations where Big's lure attack does not reset properly, disabling the move until you get hurt or reset the game.
    * I haven't tested every Froggy location some might not be as reachable as they seemed on SonLVL.
    * Technically not a bug, but finding Froggy inevitably costs you a chance to enter the special stage ring. Might try and find a way around that in a later version.
    * Some obvious colour issues due to Big's different palette.

    Special Thanks:
    To DeltaWooloo, HitaxasTV, CampbellSonic, D.A. Garden and many others on the Retro forum and Discord server.

    Okay, this is absolutely spectacular!
    I've yet to play this, but while I wait for the download, I assume that getting Froggy in every act gives some sort of secret or unlockable?

    Not yet I'm afraid, though I do wanna work some sort of reward system into this and Pink Edition at some point.

    Unfortunately, in BizHawk's Genesis Plus GX core, collecting Froggy crashes the game: [​IMG]

    And on that note, here's a new revision:

    https://cdn.discordapp.com/attachme...Big_The_Cat_In_Sonic_The_Hedgehog_Rev_1.1.bin

    Updates:

    * Should hopefully fix the crash issues on some emulators when catching Froggy.
    * Hopefully fixed motion/animation bugs with Big when catching Froggy.
    * Catching Froggy at SBZ2 now immediately transitions to SBZ3.
    * Rev 01 upgrades added.
    * Started on some palette fixes.

    Thanx to everyone on here and the Retro discord server for updating on bugs.
