I'm not sure exactly which part is the problem, but it could be either a savestate or srm read/write issue.

The bug:
I'm pretty sure it occurs in every one of the games... I'll just explain the one that is currently most prevalent.

At some point, when you reach a high level in the Lost Levels game (it's probably past level 4, but verified at level 7 and

.. when you attempt to save, the current level is NOT saved, in fact, the slot says empty. Sometimes it works (mainly in the lower levels)... but there is also a problem.

Let's say you have saved at level 8-3 (saved in Slot 1 of Lost Levels ), in Slot 1 of Super Mario Bros 2 , the level has changed to level 3, regardless of what was there before .

There is just a damned saving problem in general with the All Stars ROMs (all variants, with good checksums) where it either doesn't save and/or it affects other saved game data .

I'm not sure how to explain it better. I can provide a savestate+srm file if needed.

Edited for clarity and emphasis

AFAIK in Super Mario 3, only the world, items, and lives are saved. So if you were on world 6-10 in SMB3, and pulled up the menu to save and Quit, you'd have to start back on 6-1 the next time you play.

That is confirmed to be true my friend.

The OP said nothing of SMB3

Well I have the regular Mario All Stars without World and there are no problems saving in any game. This seems quite strange to say the least.

Is the "cheat" in SMB3 of this cart still enabled in ZSNES?

I haven't checked it out yet.

On the Penny Arcade forums, many people reported experiencing "the cheat" on a real SNES. These were people who have never used an emulator

Really? Wow, that's so f***ing cool XD

I can't test it though.. my copier gone whacked a few months back...

...So would someone mind describing this so-called 'cheat'? I assume you don't mean the Minus Worlds...

Did you read what I wrote?

They are probably talking about the cheat where you push select, and you can scroll through power ups, like fire, leaf etc. I used to have a rom like that

Bingo. I'm not sure if it still works, but it did in an older version of ZSNES. Nach, or someone else, said that it was a bug in the emulator which managed to enable a disabled debug routine. If that's the case, then I have no explanation for how these people reported finding it on a real SNES. Perhaps a flaw that causes a bit to be flipped, or a register to behave improperly? Anyway, some thought that it was supposed to be that way, and they were suprised to see that they can no longer do it on their SNES...so it's clearly not supposed to be enabled.

If I forgot to mention, this occurs in the current version of ZSNES (1.42) and previous version as well...

Enable Sram check & Save and tell us if that helps.

Nope, not at all.

Newest WIP doesn't fix it

I'll just explain steps to reproduce the bug:
1) Load ZSNES
2) Load Game
3) Select "Super Mario 2" game
4) Erase all data in Slot 1
5) Select "Lost Levels" game
6) Erase all data in Slot 1
7) Start playing in Slot 1

Select Mario as the player (I haven't tried Luigi, but I presume the bug will occur with him as well)
9) Save Game (and Continue)
10) Save State
11) Quit ZSNES
12) Load ZSNES
13) Load Game
14) Load SaveState
15) Save Game and Quit
16) Look at the Super Mario 2 data, it will say something other than NEW for Slot 1..
17) Sometimes Slot 1 of the Lost Levels data is NEW..

I believe there is a problem with the savestate/srm data when a savestate is loaded and being written to with this ROM..

This occurs whether or not SRM Check+Save is enabled.

If you want to load SRAM from Save States, just check the box for it.

Hm, that actually works....

A quirk between diffrent revisions of the deck, maybe?
