    This is so cool, I'm loving how much attention you're giving to making it feel like a complete experience. Also thanks for the exploit fix.

    This is a great hack. One thing though: during water levels (especially in Sonic 1), when you lose rings, the framerate is crawling to a very low level. It slows down to barely playable level :/

    Nice update! I just found a bug with Ice Cap Zone Act 1. When Sonic is on the snowboard, there are some glitched tiles as seen below.

    So far I haven't found anything else, but I'll let you know if I do.

    This is amazing, this is the first time this cutscene has been restored for an actual gameplay/story reason. Now Knuckles can't punch emeralds out of you that you never collected in the first place.

    Found a near softlock: hyper dashing into a bonus stage ring sends you to the bonus stage that corresponds to your current ring count, regardless of which bonus stage it would normally send you to. While I haven't tested all 4 stages yet, I figured out that hitting the checkpoint with a ring count that won't take you to the Sonic 1 special stage, then hyper dashing at a ring count that would, sends you first to the original bonus stage, then warps you to the Sonic 1 special stage. Additionally, if the normal bonus stage would be S1 special stage and you hyper dash while your ring count wouldn't, it also glitches to the S1 special stage, and you will be softlocked. It does not occur if both the bonus stage and the ring count at the time of hyper dash would lead to S1 special stage. Once you complete said special stage, you warp to the original bonus stage again. After beating/losing THAT, you keep warping to the bonus stage and dying. It's a near softlock because you do run out of lives slowly, and then eventually you'll get a game over, but at the point I was at, I had 105 lives, and I would have had to wait for all that to drain in order to escape without a reset. I don't have good video capture on the devices available to me, but it should be easy to test.

    Sorry if that was confusing, I'm unable to record video as all my emulation devices are using Retroarch on Android, and using a screen recorder recorded at 2 fps despite the game running at 60 fps.

    In Hill Top Zone Act 1, once you reach a certain x-coordinate (independent of your height, tested with debug mode), the game locks up. Music continues playing, but the HUD and all animation freezes, and you have no control. Restarting once it's frozen wipes all your save files, so you should rewind before restarting. I've included a screenshot of the spot you'd normally encounter it in, the S-pipe right before that would take you straight to it, and the debug coordinates. I encountered it naturally as Knuckles + Tails, but it occurs with all characters. It doesn't go to a crash screen, it just freezes.

    Also, Knuckles can reflect projectiles while gliding. Not sure if that's intended.
