The latest firmware upgrades can always be found here:

You may, for whatever reason, be considering upgrading to a firmware version that *isn't* the latest. If so, I will try keep a backlog of older firmware versions that will be available upon request, just ping me in the forums.

I'll just preserve a history of all firmware changes on this page:

• Fixes an issue encountered on some two-player games when using two USB joysticks

• Maps additional functions to joystick buttons for some games.
• Makes minor changes to descriptions for some games.
• Fixes an occasional scenario where an additional USB joystick is not detected until a restart.
• Fixes an intermittent audio click when opening the THEC64 Mini’s MENU in-game.
