Hack Sonic 1 Definitive - SHC 2021 Demo

Discussion in 'Engineering & Reverse Engineering' started by Inferno, Oct 11, 2021.

    Sonic 1 Definitive
    RadiantNexus Team presents... Sonic 1 Definitive!
    Sonic 1 Definitive is a hack named by RadiantNexus Team, which seeks to reimagine Sonic 1 by rearranging levels. remixing music, adding features from future games, and readding scrapped ideas in new and interesting ways.

    Major features:

    • 3 acts of reimagined level design, including one act that has yet to be fully reimagined in any other hack.
    • A miniboss.
    • Massive art overhaul all over the place.
    • Music made by ProjectFM and MechaKnuckles.
    • Menus!
    • A custom splash screen.
    There's been massive engine overhauls as well, including the Sonic 3 level layout format for massive levels, and the Sonic 3 object manager to go alongside this.

    This has been in development for over a year, so we at RadiantNexus Team hope you enjoy!

    We are aware of multiple bugs in this demo, which have mostly been resolved:
    1. The ball has a lack of collision detection in most circumstances. (This is just a lack of code.)
    2. The CD Spindash is a little inaccurate and has some bugs in Bridge.
    3. You can get a 1up by getting one more ring when you leave or enter a bonus stage.
    4. GHZ2's water palette can mess up when you exit a bonus stage. (Hardware and BlastEM specific)
    5. BZ1 will sometimes freeze. (Hardware specific)
    6. You're able to get stuck in specific Bonus Stage Bumpers.
    7. Priorities with Shields and Spindash dust are a little wonky with foreground trees.

  2. I think that's the best 16-Bit re-interpretation of Bridge Zone I've seen on a ROM hack (or even a fanmade in general?) for now. I really like how everything here is polished and the Bonus Stage is really fun!

    This hack has all the premises to become something awesome, I look forward to play future revisions!

    For now, here is a gameplay video I recorded a couple of days ago (thanks to Inferno for sharing the rom early).

    Just finished recording a gameplay video of Sonic 1 Definitive:

    Now, you may ask what I think about the hack, let this screenshot do the talking for me: =P

    Jokes aside, I'm preparing lengthy evaluations to all Retro hacks so I'll let you know when that's sorted. All I can say is, good job, RadiantNexus!

    I don't have a lot to contribute to the discussion, except to say Green Hill Zone Act 2's music is a fucking jam.

    I love all these 'upgraded Sonic 1/2' hacks that add loads of discarded extras. This one gets an odd enjoyable vibe for me. It's as if it's a long lost polished arcade version that the original two console versions based themselves on in different ways (if you've played ports of early SEGA arcade games, you'll understand why).

    Also loving your reimaginings of the 8 bit levels. I like the ways you've added more unique gimmicks and life to the admittedly bland BZ, especially your implementation of Splats. That's rather clever level design there.

    I'll just provide some Big Ring hints:
    Throw yourself down at your first chance
    Observe an unusual wall to your left

    Think like KawariNo
    Or fly upwards from the incline

    To the right of the spring
    It is in plain sight

    One side brings good luck
    What does the other side bring?

    Just above the watery abyss
    Find a passageway blocked within

    Remember those times of playing on the Game Gear
    And ride a bridge downwards.

    I played through the demo today and was really impressed. This is shaping up to be an amazing reinvention of Sonic 1, and seeing levels and ideas from the 8-bit version executed here on a grander scale is really, really cool. The art and music are also amazing. I'd say my only issue is the level design could use a slight amount of work - I feel like it's got too much stop-and-go, lacking the kinetic flow I like from Sonic levels. But that's a pretty minor issue in the grant scheme of things. This hack was loads of fun and I can't wait to see more.

    The worst thing about this hack is that it ended. Seriously, I was not ready to stop when it ended!
