Ill be back with more. let me know what you guys/and or/chicks think

[toddforester]

the binary based installation may not give the most up to date builds.

[toddforester]

no problem thats why we are here… well if we arent trying to solve our own broblems and what not. im really glad to have helped.
i hope you stick around the forum so maybe you could help people as we helped you. take a look at my project that i posted here :

let me know what you think so far.

[toddforester]

haha he beat me to it .
have fun playing.

[toddforester]

try
jstest /dev/input/js0
for controller 1 and
jstest /dev/input/js1
for controller 2
i believe it tells you the button numbers there and you can see when you press one it’ll change from off to on.

[toddforester]

oh, so I forgot /home/pi/ my mistake. and that’s weird because I’m sure I grabbed the latest image and I was able to start the x GUI ??? I could be wrong I may have grabbed an outdated version. I updated through the retropie-setup script

[toddforester]

unless I wrote the path incorrectly you should have seen the config files contents. (I’m at work so I can’t check that the path I wrote is correct). another thing to try is to startx and open the file browser and go to where the configs are kept and right click the retro arch.cfg and click to open with leaf pad. edit it and save it from there.

[toddforester]

what if I have my HDMI always connected but I want to hook up the pi to a bigger screen through composite ? all while the HDMI is still connected Is that possible?

[toddforester]

I was reading elsewhere on the forum that someone was using cyberduck and having problems try editing directly from the pi with

sudo nano /RetroPie/configs/all/retroarch.cfg

then make the changes and press Ctrl + x then y then enter to save and exit.

[toddforester]

which emulators have you tested with?

[toddforester]

thanks dude I’m glad y’all like it.

[toddforester]

thank you sir. I’ll add more to my post later today so keep an eye out for updates.

[toddforester]

I’m not able to see your config file. I had to rename mine from .cfg to .txt in order for it to upload properly.

[toddforester]

yea i have done it before only to lose it all. but now my pi has a permanent home so i might do it again but i have a few more important things to work out first.

[toddforester]

i think it would be great to be able to add my own games (if i get around to doing it on the pi, ive made games on psp(Lua) and then moved on to pc with various languages) but lets say i make pong in python with pygame or c++ with sdl would it even be possible to add them into emulationstation?

[toddforester]

default video 8bit super mario mushrooms floating about. either that or it could just load pictures from a folder and fade in/out until input is detected so we could make our own “gallery/slide show”. i think it would be easier to start with displaying the pictures, then move on to video but hey what do i know.

[toddforester]

it would be cool if, say you were in the nes menu and go to config setup it would have the option to save changes for 1) This console or 2)All.
just an idea.

[toddforester]

or a place in the config that would allow you to choose between hdmi / composite so all you would have to do is ssh in and change a line in the config to choose hdmi or composite out or just change it in x or the terminal and reboot.

[toddforester]

Nice job and great video. and thank you for posting it. im glad to see that this forum is active (im a new member as of a couple days ago).

I also really like your custom themes especially the nes theme anyway you might upload it somewhere i would like to use it if you dont mind, thanks.

[toddforester]

i did it by starting with noobs then installed Raspbian and then from there installing retropie like this [url]https://github.com/retropie/RetroPie-Setup[/url]

[toddforester]

it is hdmi. it is this screen actually (pretty good deal a year ago when i bought it for $100) [url]http://www.amazon.com/Lilliput-monitor-interface-dedicated-high-definition/dp/B0041I8UAO[/url]

[toddforester]

hi, i had a good laugh when i read “technically inadequate” so thanks for that.

ok so what happens when you do
ls /dev/input/
in the console?

it should show js0 and/or js1 amongst other things.
also could you attach your config file located at
/home/pi/RetroPie/configs/all/retroarch.cfg
in your reply so we could have a look at it.

for my (original) nes controller i have this in my retroarch.cfg

# If desired, it is possible to override which joypads are being used for player 1 through 8.
# First joypad available is 0.
input_player1_joypad_index = 1
input_player2_joypad_index = 0

input_player1_a_btn = 3
input_player1_b_btn = 1
input_player1_start_btn = 7
input_player1_select_btn = 6
input_player1_left_axis = -0
input_player1_right_axis = +0
input_player1_up_axis = -1
input_player1_down_axis = +1

input_player2_a_btn = 3
input_player2_b_btn = 1
input_player2_start_btn = 7
input_player2_select_btn = 6
input_player2_left_axis = -0
input_player2_right_axis = +0
input_player2_up_axis = -1
input_player2_down_axis = +1

the part about input_player1_joypad_index = 1 is like that purposely because i wired or read a diagram backwards but if that is the only controller plugged then yours should be
input_player1_joypad_index = 0

i have faith that the awesome members of this forum will be able to help you solve the problem with the right bit of information.

i have attached my retroarch.cfg so you can look at it.
go down to the input section (while looking at the file press ‘ctrl + f’ and in the search type “#### Input”)

[toddforester]

oh that’s cool I didn’t know about the tab thing thanks for that. does it only work with emulationstation or is that a Linux thing?

[toddforester]

I’m not sure if this is a related issue but I am using a 7″ monitor and the console text and xgui are every small, almost unreadable. I have tried changing some things in the boot config but when I get the text readable emulation station won’t start. any help is appreciated.

[toddforester]

if it is already installed just type “emulation station” without the quotations.

[toddforester]

also I think the data lines are backwards in the diagram above or (software?) because player 1 is js1 and player 2 is js0.

[toddforester]

thank you all for the replies. I ended up connecting vcc for both controllers to gpio pin2 (5v) and crossed my fingers that my pi didn’t explode when powered. to my surprise IT WORKED!!! I now have both controllers working perfectly. I have read that there is supposed to be some protection (diode+resistor?) on the data pins could you tell me how that is supposed to work?

[toddforester]

so i poked around with my oscilloscope on the data lines of both controllers and it seems like player1’s voltages are higher than player2’s i can see when i press buttons on both 1 and 2 … also with a multimeter i checked the data lines of both. player ones normal voltage on data is == 3.25 . player twos normal voltage is == 1.71 . i am confused??? im powering both controllers from gpio pin1 3v. any ideas? im thinking maybe ill try 5v but i dont want to burn the pi.
