Is Marvel vs. Capcom 2 Backward Compatible on Xbox 360? No—But Remaster and Modern Collection Exist
No. The original Xbox version of Marvel vs. Capcom 2 is not on the Xbox 360 backward‑compatibility list. Microsoft ended the BC program in 2007, and this title was never added.
Ways to Play on Modern Hardware
Emulation (PC): Use MAME (arcade version) or Xenia (Xbox 360/PS3 ports) with a legally dumped ROM/ISO.
Marvel vs. Capcom 2: New Age of Heroes (Remaster): Released in 2009 on Xbox 360 (Xbox Live Arcade) and PS3 (PSN). It features HD sprites, online play, and gameplay tweaks. Note: This is a separate purchase; your original Xbox disc will not work.
Modern Collections: The game is included in Marvel vs. Capcom Fighting Collection: Arcade Classics (2024) on PS4, Switch, and Steam.
