Custom arcade controller for TI-99/4a ?

[J.Ivy]

So im bored, wanting to make an arcade style controller for my TI. I have an old (broken) NES advantage arcade controller hanging around. It went through a flood and never worked after that.

 

Why not rewire it to work for my TI?

 

I should be able to locate what pins do what on a TI controller, then use those to hook up to the Advantage. I dont THINK it should be too tough

 

What do you all think?

Interesting... of course the turbo function would be considered cheating, especially with Rasmus' Sports Game.

I'm sure you would have to introduce power from second source as well. I can't wait to see how this turns out.

This should be a fun little project. Ive read up on a few DIY arcade controllers. Shouldnt be all that tough

 

Plus, im a pack rat, i hate tossing anything out and repurposing is a good way to avoid that.

That is cool. The week before last I rewired a brand new neo-geo-x arcade stick to the 4a.

 

It had four buttons, plus a start and select. I wired it so that the extra buttons used joystick 2. And such that all four buttons could be pressed at the same time for combos.

 

A - player 1 fire

B - player 2 fire

C - player 2 left

D - player 2 up

Select - player 2 down

Start - player 2 right

 

All can be read with normal joystick routines.

Also, I wrote this when I first picked up my TI so I could test atari joystick adapters and such... I keep finding it handy...

100 CALL CLEAR
110 DISPLAY AT(24,1):"jedimatt42 matt@cwfk.net"
120 DISPLAY AT(1,1):"Joystick 1"
130 DISPLAY AT(1,17):"Joystick 2"
140 J=1
150 CALL SHOWJOY(1)
160 J=2
170 CALL SHOWJOY(2)
180 GOTO 150
190 STOP
200 SUB SHOWJOY(J)
210 REM  SHOW JOYSTICK
220 REM  WHERE J IS 1 OR 2
230 CALL JOYST(J,X,Y)
240 CALL KEY(J,K,S)
250 IF K=18 THEN F=42 ELSE F=0
260 X=X/2 :: Y=-Y/2
270 C=((J-1)*16)+6
280 CALL HCHAR(5,C-1,F)
290 CALL HCHAR(6,C,0,5)
300 CALL HCHAR(8,C,0,5)
310 CALL HCHAR(10,C,0,5)
320 CALL HCHAR(8+Y,C+2+X,35)
330 SUBEND

Micro pinball II uses player 1 and player 2 fire buttons for the two flippers.

 

Any other games folks know of that use both fire buttons?
