Big Blue (2015/06/27) is released. Big Blue is a frontend for any command line program (MAME or any game) that works on any setup. You can use it with an arcade cabinet with a 15khz arcade monitor or a desktop computer with a 3840x2160 monitor.

What's unique about this frontend is that the frontend itself is a video game. Player 1 and 2 can fight each other to determine who gets to select the game.

* FREE! Source code available on request; let me know if you find problems or want to make improvements

Big Blue Changelog：:

- Big Big configuration utility's "Add MAME" form dynamically populates the list of manufacturers from all the unique entries in the listxml output instead of being a hard coded list
- If your default game list wasn't the first list, returning to the categories menu had the wrong selection
- If you're holding down the R-Type warp button while selecting a game to launch, the warp sound no longer continues to loop after the game's been selected
