I went and recreated • Mario Paint "Data Over... using a GV-USB2 capture device and a real SNES, and I included the full process of me setting everything up to cause the error.
It's really easy to do! I saw a suggestion to do it with a custom stamp which I did here, but you can also do it with a premade stamp (like the one of Mario's head), the spray tool or any other method of making something that looks very messy. Just keep in mind that you do need to do this to both the main canvas and the animation frames.
This error happens because Mario Paint's cartridge includes 32 KiB of save memory, but that's only enough for the main canvas or the animation frames but not both. The game solves this with compression, and if the data is random enough then it'll still be too big to fit after compression.
If you're not familiar with Mario Paint you might notice that Mario Maker actually references it quite a bit.

I wasn't expecting a sequel and I'm pleasantly surprised

I saw comments here and there asking if it was real, asking about reproduction steps, or giving me advice to use a higher video resolution, so I figured it would be quick and easy to just make a better video. It was also clear that a lot of people who watched the original hadn't actually played Mario Paint, so I thought it would be helpful to have a short video that shows off a bit more of the game that people might not be familiar with, like the stamp editor.

They even had a little animation for the robot overloading! That's adorable!

This makes me curious how Mario Paint's compression algorithm works, particularly since it seems a fair bit more complex than, say, the one for 1st gen Pokemon sprites.

@bushytail Месяц назад

It's a mix of LZ77 and Huffman, which are also the main concepts behind PNG compression. There's decompression code at forums.nesdev.org/viewtopic.php?p=199067#p199067

@yourhighschoolenglishteach8405 Месяц назад

they must be pushing the limits of the console if a normal drawing saves fine, but a particularly detailed one breaks it

@bushytail Месяц назад

In this case the limit is just how much save memory is in the cartridge, rather than a console limit. It can handle this much entropy on the main canvas or on the animation frames, but both at once results in a save file that's too big.

@@bushytailIt's using a simple compression algorithm right?

@bushytail 13 дней назад

@@sagesys According to reverse engineering that's been done, it's a combination of Huffman coding and LZ77, which are also the main techniques behind PNG. I'd consider that to be pretty complicated, and I imagine Nintendo did that because it will do a good job at arbitrary repeating patterns while something like Run-Length Encoding would not.
