What “No-Intro” does is fill some .dat files, to be used with ROM-Managers, with information about the known ROMS released. Often there are more versions of the same ROM dump, but most of them are garbage, some examples may include: bad dumps, hacks, fakes, overdumps, underdumps, and so on. “No-Intro” lists only the best available ROM; it must be a full dump with no faults and no changes to the file, basically just the ROMS that are the closest as possible to the original licensed cartridges.
Our goal is entirely different to yours!
When this project was born its goal was to remove the intros that some pirate groups added to the Game Boy Advance ROMS.
This is why it’s called “No-Intro”.
In later years, we’ve covered more and more systems: after all the hard work on GBA, GBC, N64, e-Reader and N-Gage, we opened more fronts of preservation.
