>>43388370>Didn't nintendo straight up just download ROMs from the internet for some VCs, same headers and all? I don't remember the whole storyThat was speculated for a while but the reasoning behind it is that the original Wii release of Super Mario Bros had an ines (a popular early NES/Famicom emulator) header, however, what people don't realize is that the guy who developed the original iNes emulator all the fucking way back in the early 90s got hired on by Nintendo in the mid 90s after Nintendo found out about the emulator. He still works at Nintendo today as far as I'm aware. Those same roms with those same iNes headers are also in the N64 version of Animap Forest, and by extention, the Gamecube version of Animal Crossing, including Clu Clu Land D, which was an NES port of a Famicom Disk System port that had never been released previously, and thus couldn't have been downloaded from the internet. Also the Classic NES/Famicom Mini series of GBA games, which are literally just NES roms running on an emulator for the GBA. Said emulator is the only reason Nintendo ever implemented a sleep mode into their later GBA games, because it was a default feature on the emulator and it was actually a pretty popular feature.
The most likely reasoning for the ines header is that he (or someone else at Nintendo) used ines to test Famicom romfiles at some point, which automatically applies the header to the rom.
