Hello, I wanted to know if anyone had the same problem as me, I started making my first level, and at some point when tryng it it got glitchy, red pixels grids all over the upper screen, and this whatever the emulator I used. I figured I maybe suppressed something wrong while making my level, as I supressed everything in W1-1 to make my new level over. Someone asked if I didn't messed up with the overlays which I think I didn't but one file in the overlay 9 looks different.
It's been weeks and still didn't managed to find the problem, please help ?

Could you please post screenshots? Then we can see better what exactly's going on. And what do you mean with "suppress"? I don't think that was the right translation... do you mean "delete"? But either way, chances are low it's an emulator issue, as the glitchy red pixels appeared in every emulator you used.

By the way, this does really smell like ROM corruption. Best would be to make an editor screenshot of your custom W1-1 and use it as a reference to rebuild it on an earlier back-up ROM. Do make back-ups whenever you open the ROM to change anything: ROM corruption was the cause of New Super Hacker Bros.' cancellation.

yeah I meant deleted sorry
I didn't did backup oopsi

I'm not a NSMB hacker, nor am I a gambler, but it's a safe bet this is indeed corruption. It's not glitched particle effects, as the snow looks normal, and hell, even Mario is covered by a red bar! I suggest making a screenshot of your levels in NSMBe, so you won't have to rebuild everything from memory, and start over on a clean ROM.

And to make back-ups

ama gonna do that, guess I can export import levels anyway so if the problems aren' level can fix that
many thanks friend !

EDIT:


I have some news. I tried two things: import my levels in a fresh rom, and play a totally new unedited rom. In both cases the glitch still hapens. Could it be my computer ? I noticed a few things, it might be linked to a mario sprite problem: when I jump high off screen or fall in a pit death the bug stop for a few secs.

Really weird sorry

So the game stops glitching out if Mario is offscreen. Hmm... Mario is a 3D model. Does the glitch also happen on the worldmap? And could you try to make Mario go offscreen in a level with a Snailicorn or Bowser Jr.? Those are, among others, 3D modeled too. Because the glitch happens on a clean ROM too, it might be your computer... its 3D engine or something. I'm not very technical though. Do you have access to another device that could play this game? Then you could copy the ROM and emulator to that other device (or only the ROM if you have a DS and a flashcard) and see if it still glitches out on the other device.

Now that you say it, very strange but the glitch start occuring when you load the first level, and then happens on the worldmap too. Could be my device tho, my laptop is an antiquity, unfortunately I have nothing else available now /:

However I uploaded my level in the hacks forum, maybe you could play it if you want and tell me if it occurs on your devices too. Thank you for evrything by the way
