No-Intro focuses only on games published on cartridge media (Master-System, SNES, N64, Gameboy, etc).
No-Intro keeps only the best roms, without errors or changes, and which are as close as possible to the original cartridges.
No-Intro usually contains only one working version of each game for a given country (US, Eur, Jp, Fr, De, ...) as well as all updates of these games (Rev1, Rev2, Beta, ...).
Redump focuses only on games published on optical media (CD, DVD, ...) (PlayStation, Sega Saturn, GameCube, Dreamcast, etc).
Like No-Intro, Redump keeps only the best isos, without errors or changes, and which are as close as possible to the original media.
Redump Isos are bigger than Tosec or Trurip Isos, but they have a better quality, which directly influences the behavior during emulation.
