Example link: https://pegasus-online.pl/gry/gba/the-legend-of-zelda-the-minish-cap-pl Example save state: Legend of Zelda, The - The Minish Cap (Europe) (En,Fr,De,Es,It) (PL).state.zip

The site appears to use EmulatorJS 4.0.5

This particular site allows users to directly download a save file, so it doesn't seem worth looking into further for now.

The offsets look a bit different: save size appears to begin at 0x61013 rather than 0x61004, and save data appears to begin at 0x61040 rather than 0x61030

Although this file from the same site appears to not share the same offsets: Pokemon - Leaf Green Version (U) (V1.1).state.zip

It's possible there's no save data in that file, since the user may not have known to perform an in-game save. But the save size reads as 512 bytes which is not correct.
