Mouser Joystick Patch

by gdx on 22-04-2018, 09:03

Joysticks was supported in game but not in selection menu. It is especially inconvenient when using a wireless controller. That's why I made these patches that that allows to start a game with joystick.

Usage is as shown below.

Press button 1 of joystick 1 to one player game.
Press button 1 of joystick 2 to two players game.

When the patch is applied, [Select] Key allows you to display the menu in game.
If you hit [Select] key twice time it switches the character directly.

You can also use a JoySNES or Mega-2-MSX adapter instead of an FM-Town
controller.
