I built an analog loom for a sega jamma i/o in order to the play world series baseball on my blast city, using the pinout from the analog splitter loom and the CN7 pinout. Works great !
Code: Select all
10 pin AMP UP Female 26 Pin JST RA Female
01=AChannel0 03
02=AChannel1 09
03=AChannel2 15
05=AChannel4 04
06=AChannel5 10
07=AChannel6 16
09=AVCC 01
10=GND 05
Now , I would like to use the P1 analog stick to play monkey ball as well. It doesn't seem to work. When I go to test mode, game settings, input test , I see the H and V numbers move through consistent ranges of values as I move the stick. But when I try to play the game, it's not moving the monkey, or doing anything at the player/difficulty selection menu.
I know that it can be done with a zombie's revenge panel. ( http://www.sega-naomi.com/forum/viewtopic.php?t=3740 ) . In this post , goat boy used an adapter to swap VCC and Ground. I tried to do that ( swap pin 9&10 on the AMP UP ) It does reverse how the value changes in the input test menu, but it still doesn't actually work in the game.
I tried to locate a Monkey Ball manual online to find out what parts and pinout it was using, but nobody ever scanned one and posted it online...
Does anyone have any clue what I'm missing here ??
Thanks !
