Street Fighter 30th Anniversary Collection brings together the arcade versions of 12 (13 in the Switch version due to including Super Street Fighter II: The Tournament Battle) games in the franchise, from the original Street Fighter up to Street Fighter III: 3rd Strike, as well as having bonus features such as a museum, a music player, character biographies, and an interactive timeline. Its release was delayed in Japan to address fan feedback.
To do:
Look into the game's .MBUNDLE files for more unused content.
This unused green belt icon appears in the game's bundlemain.mbundle file, used as a placeholder for the final belt icon graphics until they were created.
The compilation has some differences of its own between regions, and the regional differences in all of the playable games themselves are the same as they were in their original arcade ports.
The logo is different for each region on the title screen, and the Japanese version added the copyright text below. This also applies to certain areas of the game's menus, and the game's logo artwork in the Museum's Interactive Timeline.
The worldwide version features only each game's world versions, while International features the ability to swap between the games' US and Japanese versions, with their logos also being altered.
