    Nice find! Is there anything interesting in the options beyond what's available in the regular game?

    You can access the remnants of the Coming Soon screen :specialed: You can also play Media demo mode which is just Green Hill Zone followed by a buggy, muted Studiopolis Act 1. I haven't been able to get through that version of Studiopolis without the game crashing though. Also another mod:

    It's literally a sprite hack that puts Knuckles sprites over Sonic's, resulting in a Knuckles that has all of Sonic's abilities and can have Tails follow him... so that's kinda what I wanted

    In the dev mode there's a classic style stage select.

    edit: Nevermind! Never unlocked Debug Mode on the Switch.

    That's in the full game, too. Once you unlock Debug Mode, you just hit Square and X (or whatever your equivalent is) together at the title screen.

    You too can finally get that damn fifth chaos emerald...after playing through that stage through the dev menu over and over again:

    It shows up in No Save mode. You get one by getting a Mach Bonus (that is, collect enough Blue Spheres when you're already in Mach 3). And when you use a Continue, you start from the Act you died on instead of the Zone.

    In a No Save game, get 10,000 points in a Special Stage. (easiest way is to get the Mach Bonus)

    The CRT shaders used in the game are pretty good, specially "CRT-Yee64" (according to the devmenu).

    Any idea if it would possible to extract those? retrun only yields binaries (probably some corrupt), I guess the archive format changed too much.
    I wonder if the HLSL files are in there somewhere?

    It'd be better than dumping them to ASM for sure.

    OOoooooh boy, this gets me pumped! I wonder how they were able to do it so quickly? Even as just a sprite swap I'm curious to see how it can be done.

    4th says the same to me too, so I don't want to know how the 5th is. XDDD

    For me 3rd, 4th and 5th. Especially the 5th. I don't know how many times I tried, but I wanted to kill myself everytime I went through it, and it made the 7th one look like the 1st Special Stage in Sonic 1.

    https://www.youtube.com/channel/UCEjwges-3BTaWsMwOGJDoGQ Beatz here seems to be uploading small spriteswaps for mania en-masse. Let's see where this leads...

    I've taken a look at his EXEs. All he is doing is replacing which sprite file the game is searching for by, for example, changing "Players/Sonic.bin" to "Players/ChibiSonic.bin" in the EXE. He actually had to blank the following entry "Players/SuperSonic.bin", to fit the new string in, so chances are the game will crash if the player transforms.

    yea aight this is p. huge. Excellent find, don't know how you did that outside thinking it'll work... a bit surprised it did :V

    I figured since the EXE probably isn't encrypted and it's looking for strings in the ini file, that "devMenu" would be in the EXE somewhere (is that how you found it, looking for "dev?"). Figured there'd probably more stuff hidden in "game" that'd be discoverable that way.

    Didn't find much, buuut...

    Seems there's likelihood for a "mod loader" to work after all, at last a fan one :^)
