Hi... JrPS2
Moderator:Moderators
hi... for some weeks(or months maybe) i have working on a portable ps2 that im goin to call the JrPS2 (all the goods name like PS2p and PS2m was already taken... ) there still some thinks on the desing that i think i have to change (like adding the select/start ... i already the console (slim one) the battery that is a custom 8.4v 10a li-ion (ten of This battery) and the psone screen
this is a preview of the think...
im still need to add the sellect ans start to that desing.... im also goin to add 1 usb port, 2 internal switchable ps1/ps2 memory cards and external ports for player 2 controller/memorycard... im also planing on put two blinking leds for the rumble function, for games like shadows of colossus you need to fell(in this case see) when you spot something...
i try to use the analog of the bottoms but is a pain. to find the way to doit... so i deside to use THIS soft felling bottom so they feel like the originals
i dont know what else to do whit this... i just have to find some time to finish this work.
any sugestion please let me know

Trust me, the L1 & R1 thing you have going wouldn't work out too well. You'd have to have your fingers lying on the buttons like an arcade control panel.

I can tell you right now that rewiring the ps2 contoller is MUCH harder than it seems. You're probably thinking 'How hard can that be?' but simply wiring a button to the pin that supposedly operates a function doesn't simply work. maybe 2 or 3 buttons could do that, but not the L and R buttons. Just a heads up.

about the bottons layout... i actually use all gamepads like a arcade ...
1- at base
2- for X and Square
3- for Triang and Circle
4- R1
5- L2
i allways buy a 6 bottons layout pad for my consoles... any way i goin to make two consoles... one whit 6 and one whit 4
on the controller rewiring ... i notice that i wont be easy... i just have a theory of how they work...
look at this pic ...
click to enlarge
A = ground
B = some kind of signal
C = Resistor or jumper that tell the controller the minimun ohms(maximun presure) wen a botton is pressed at full
D = Variable Resistor
my theory is that if i place a jumper from A to B and place a resistor of 20ohms (or 100ohms, or 1k) in paraller whit each bottom like these pic the controller must work

that's a hell of a theory! I've been having difficulty with the re-wiring of my L and R buttons. this should help a helluva lot. So if i wire a button to the B pin and the pin that R1, R2. L1, and L2 pins are, they will work?? I sort of cant get my PSTwo to work cuase my modchip install wasnt 100% Those are some damn small contacts. My laser isnt working right, but i will test later.

for the little research I made...
-each botton from they signal to -B- have a resistor value of arround 20K ohms when not pressed....
-the resistor that is from -A- to -B- is 5k ohms
i believe that the sistem detect full presure of a botton when it arrive the value of 5k... so one of these two way it will work...
A---
Code: Select all
__S1
Botton Sig SQ--{__}----\
R1 |
__S2 |
Botton Sig X--{__}----{
R1 \ ____-B-__R2__-A-
__S3 /
Botton Sig L1--{__}----{
R1 |
__S4 |
all bottons --{__}----/
R1
R1 20Kohms
R2 5k
here... when a botton is pressed it will go direct from 20kohms to 0 ohms
B---
Code: Select all
__S1
Botton Sig SQ--{__}--R2--\
R1 |
__S2 |
Botton Sig X--{__}--R2--{
R1 \ ____-B-__R3__-A-
__S3 /
Botton Sig L1--{__}--R2--{
R1 |
__S4 |
all bottons --{__}--R2--/
R1
R1=15k
R2=5k
R3=5k
here... when a botton is pressed it will go direct from 20kohms to 5kohms
