Here's a new fork of Nintendont: Nintendont-CrisMMMod
There are a few improvements on Triforce playback I've personally implemented (my nickname on this website is AnthonyRyuki). Of course, F-Zero AX benefits from them, too.
Here's a list:
-The way F-Zero AX's language was set to English was through RAM hacking, but I more properly changed the region setting in the Triforce system instead, so some text became more legible.
-In F-Zero AX and Mario Kart Arcade GP, it is now possible to switch between the A and B buttons and the L and R triggers for the pedals. The former has the benefit of being comfortable to use, the latter allows for full control of the pedals as they are analog in the original arcade machines.
-In Virtua Striker 2002 and Gekitou Pro Yakyuu, it is now possible to also use the D-pad to move your character, along with the Control Stick. This makes sense, as the original arcade machines use a digital joystick.
-In Virtua Striker 4, it is now possible to set the announcer's language to Italian via the Test Mode, though Sega removed it in Ver. 2006.
-Also in Virtua Striker 4, when playing the game with a Wii U GamePad, the game would register a down input when pushing the analog stick all the way up. This was due to a bug (incorrect offset) on the Y axis that I fixed. (Note that the original arcade machine uses an analog joystick.)
Hope you'll check it out.
