Mega Man Anniversary Collection

Mega Man Anniversary Collection is a game released by Capcom and Atomic Planet in 2004 for the Gamecube, PS2, and Xbox. The game is a compilation of Mega Man 1-8, with 2 bonus arcade games : Mega Man: The Power Battle and Mega Man 2: The Power Fighters. Completing certain objectives will unlock bonus content, such as music, artwork, or videos.

NES Titles (Megaman 1 thru 6)
Megaman 1 - 6 have minor graphical glitches inherent to the original games but are playable. However, the audio is heavily distorted and garbled when using DSP HLE emulation. Using DSP LLE recompiler with audio backend: XAudio 2 seems to fix the audio problem.

Mega Man 8 Full Motion Video (FMV)
Megaman 8's FMVs have audio, but no video.

Megaman 8 Corrupted Visuals
Megaman 8 also suffers from corrupted visuals, but it is not as bad as the NES titles.
