Screwing around in Debug Mode

Some wierd ass shit can happen in debug. Just today I played around with just Sonic 3 alone, put the level select code in, entered a bonus stage, exited back into the level select, where it was all horribly scrambled. However, I could still choose a zone and did so, causing the game to send me in a random part of the zone with "Hydrocity" as the title card. Did this with every zone, same result. Gonna try to do it again and get pics up if anyone is interested.

Also, entering the competition zones while glitched like this will make the screen scroll vertically non-stop.

Note: This was playing the game via SMC+. Also, in level select, you are able to play the music from the Sonic & Knuckles Zones. This might be a known fact, but this is the first time I've ever got the level select code right for Sonic 3 so bite me. :P

 

After the flames you already are in Act 2. :P

Something similar is possible in Icecap Zone without even needing debug. Make sure you're in non-locked-on mode, go near the end to where an ice barricade blocks you off from where Knuckles' boss would be, then use the crouch-and-jump-to-make-the-screen-scroll-the-wrong-way trick to allow you to pass right through the barricade. Where Knuckles' boss would be, there's no boss instead since you're not locked on, and you get to advance onto the act 2 map while it's still act 1.

 

I thought this was already kind of well known? How the game was put together, that is. This could be me talking completely out of my ass, but this is how I've observed it:

Acts 1 and 2 of Zones are one long thing, the boundaries are set at the start of the new Act usually. Hitting Egg Prisons, defeating Mecha Sonic, beating a miniboss and letting the post fall, etc, end the Act. It will start the new act REGARDLESS of where you are.

 

Here's a weird one. Two AIZ Robotnik bosses!



I pulled this off a few days ago, and have no clue how the hell I did it. I just used debug to randomly fly around, and then went to the boss.

For the curious, here's a savestate: sonic and knuckles sonic 3 jue.zip - 0.06MB

 

I've seen that only once, when I was messing with debug (in S3&K) and I have NOOOOO fucking clue what sets it off.

 

One AIZ Robotnik boss is bad enough. :/

 

Maybe it tries to trigger Knuckles' version as well, and since it's in the same place, there's just two of them. Whereas the mini-boss is in different places for Sonic/Tails and Knuckles, and even if you enter the other's arena, the correct mini-boss still appears.

 

I've done just about all these glitches before, except for the double Robotniks. But I have done something similar to that at the Sky Sanctuary Zone, where there were two Mecha Sonics. And I have no clue how I did that, either. Maybe it had something to do with the "S" monitors, because I DO happen to use those, a lot.

 

Question. How is there time when you are using debug?

 

When you turn of debug ( I think its C you press ?) the time appears when your in debug mode the time goes all messed up.

 

I thought it was always sprite count.

 

It can also be done in S3 as well. I suppose the level was just the left untouched where Knuckles should have gone through, but you can make Sonic go through with Debug.

 

Sonic 3's time, score, etc, stays accurate until you actually go into debug.

 

You can get up to 3 Mecha Sonics by making extra teleporters during the 3rd SCZ boss fight.
