ROTJ (jedi) authentic controls question

[Tiger-Heli]

I posted the following message on the MAMETESTERS board and no one has answered, so I thought I would give the folks here a shot at it:

I have a question on button assignments and controls in Jedi.

KLOV list this game as Directional Yoke with common triggers and thumb buttons.

Starwars is listed as four buttons in MAME, but all buttons have the same function - FIRE.

Esb is listed as four buttons and the thumb buttons shoot tow cables on the Imperial walkers screens. All buttons are FIRE on all other screens.

Jedi is listed as 3 buttons in MAME which seems odd in itself. Button 2 is mapped to the triggers, b/c when it says pull trigger to start, only button 2 is read.

Buttton 1, 2, and 3 all function as FIRE, except on the alternating AT-ST Walker/ and Millenium Falcon Death Star assault stages. On this level, only Button 2 (triggers) function and Buttons 1 and 3 don’t seem to do anything.

Can someone verify this is accurate: i.e. the thumb buttons do not work on the AT-ST walker stages, either by reading the source code or verifying on a real machine.

It may well be correct, but KLOV doesn’t mention this and it seems unusual.

The basic question is: are the thumb buttons supposed to work in Jedi.

Setting up MAME to work either way is simple enough, but I don't know how the game is supposed to work!
