I discovered something odd in SMW: if you continuously jump on an enemy (in this case, jumping fish) for a really, really long time, the number of enemies you have jumped on in a row gets reset.
In other words, after jumping on a certain amount of fish (or any enemy) without touching the ground, you stop getting 1-ups, and it acts as if you touched the ground and started over. Here is a video to show you what I mean:
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/214c0oWFUEI&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/214c0oWFUEI&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>

I wasn't counting, but my guess is that you eventually got FF (255) consecutive 1-Ups (well, bounces), so the counter rolled back over to 00.
Nice work on hopping that many times.

Interesting! I think it's because some ram address or something gets reset to 0 after a while.
edit: A ninja explained it quite well.

Yep, it was 255... I should've thought of that.

Yes, because RAM's values can't be greater than FF.

Yup, looks like you made $1697 exceed. Something similar happens with $141A, when you enter 256 pipes or doors in the same level, the level will reset.
Nice job on finding this, although the result was quite expectable.

Happy Fuzzy-Buns: enterind 256 pipes and reset level... this is awesome, but I think nobody tried it yet.

What happens if you make a patch or levelasm that decrements the ram address for the level number thing and the 1-up thing whenever you activate it or something? Would that fix those glitches even though they are extremely unlikely.

Could pretty easily make a patch that stops this from overflowing. Not sure about the level number one (though it'd probably work to).

What exactly happens with the level reset?

I did. Iceguy did. Nekoh did. A few others did.
But it could be pretty noticable in a long pipe maze level.

Roy: oh yeah. Sorry for my incovenience. I said that because in many hacks I played (except DWTLC and those Screen-Scrooling Pipes) I've never seen huge pipe mazes.

I made a patch to fix this.
Haven't tested it, but I don't have the patience to actually do it.
I guess some patch moderator will have to. *shrugs*

I remember Iceguy making a patch for it, but not submitting it because:
1. The bug was barely noticable.
2. It was super easy to fix.
Eh. His one simply stored #$01 to $141A, this one could've done that too but who cares.

I tested it with the parallelworlds patch while trying to add it to the parallel patch, and it seems to work alright. Altough I couldn't text the life part.

Is there another addresses which reset like the ones here?

I wonder if there is anything else to find? (You got the lives and the pipes/doors part), but I wonder what other things might be affected?

There could be many other things, but I'm not sure what they could be...

I think personally ALL RAM addresses which have values from $00 to $FF can reset.

Wrong, if this where true then the powerup would reset. Meaning mario would return to small.
