UAE4All2: Joystick Recommendation

kirschsuppe

Hi. I realized that my PS3-Sixaxis does work to some degree (up, down, left, right), but the Buttons don't. As I read in the documentation, the controller support is hardcoded and not configurable. Which controller do you recommend to buy.

My requirements are trivial:

It has 2 buttons: one is mapped to amiga-fire-1, the other to amiga-fire-2
the directions do work

Will any cheap controller do? I doubt that because of my sixaxis experience.
Thanks in advance, kirschsuppe

Well, the Wiki recommends the picade or anything else that is specifically designed for MAME use. This is stated to be because their control schemes are similar. You could also have your choice of controllers if you learn how to keymap. Some information on this can be found at...

Thank you. That is a nice hint into the right direction. If I use "Linux Joy Mapper" now to get my joypad to work in UAE4All2, does it overule my settings in emulationstation / retroarch?

@kirschsuppe

It will override, but the instructions include a way to have it initiate alongside KODI. You would need to adapt that technique for UAE4All, but there are actually a few possible ways to launch and quit the mapper in tandem with whatever application you want. I've recently taught myself the ins & outs of xboxdrv as a universal joystick driver and plan to start on LJM next. My goal is to have universal controller support throughout my RetroPie setup... and of course, two chicks at the same time.

Thank you. Maybe there is another alternative: to overwrite the configuration right in the code. I found a post in the interwebs to checkout, manipulate and rebuild Hatari. Maybe (if the code is readable) this knowledge can be transferred to UAE4All2.

Has anyone found a (relatively) simple way to custom map a controller's buttons for UAE4All2 yet? I'm also using official Sony PS3 controller but it's far too unwieldy to use the left analog stick and L3/R3 for fire. Would much rather use the d-pad and X/Square (A/B).

kirschsuppe

I did not find a way to use the dpad (yet). But I found a way to make the analog stick usable and use X aus the primary fire button. Stay tuned.

Edit: found a way to enable the dpad

Description

You have to:

ssh into your pi box
checkout the sourcecode for uae4all
find and change the file with the controller configuration
recompile the sources
copy the compiled binary over to where retropie expects it

What will you change:

configure a deadzone for the analog stick to prevent unwanted movement to one direction
enable the dpad on PS3 Dualshock 3 and Sixaxis controllers
enable the X Button as primary fire button on PS3 Dualshock 3 and Sixaxis controllers

CLI history

cd ~/RetroPie-Setup/
sudo ./retropie_packages.sh uae4all sources
cd tmp/build/uae4all/src
sudo nano od-joy.cpp (see changes below)
cd ~/RetroPie-Setup/
sudo ./retropie_packages.sh uae4all build
quit running uae4all
sudo mv /opt/retropie/emulators/uae4all/uae4all /opt/retropie/emulators/uae4all/uae4all-old
sudo cp tmp/build/uae4all/uae4all /opt/retropie/emulators/uae4all/
start uae4all

Changes in file od-joy.cpp

Step 1

remove the following lines completely (around line 40)

extern int dpadUp;
extern int dpadDown;
extern int dpadLeft;
extern int dpadRight;
extern int buttonX;

Step 2

add

int buttonX;
int dpadUp, dpadDown, dpadLeft, dpadRight;

right before statement

SDL_Joystick *joy = nr == 0 ? uae4all_joy0 : uae4all_joy1;

Step 3

add

buttonX = SDL_JoystickGetButton(joy, 14);
dpadUp = SDL_JoystickGetButton(joy, 4);
dpadDown = SDL_JoystickGetButton(joy, 6);
dpadLeft = SDL_JoystickGetButton(joy, 7);
dpadRight = SDL_JoystickGetButton(joy, 5);

right after statement

SDL_JoystickUpdate ();

Step 4

Find this block (around Line 150)

if (dpadRight || SDL_JoystickGetAxis(joy, 0) > 0) right=1;
if (dpadLeft || SDL_JoystickGetAxis(joy, 0) < 0) left=1;
if (dpadUp || SDL_JoystickGetAxis(joy, 1) < 0) top=1;
if (dpadDown || SDL_JoystickGetAxis(joy, 1) > 0) bot=1;

and change it to

if (dpadRight || SDL_JoystickGetAxis(joy, 0) > 8192) right=1;
if (dpadLeft || SDL_JoystickGetAxis(joy, 0) < -8192) left=1;
if (dpadUp || SDL_JoystickGetAxis(joy, 1) < -8192) top=1;
if (dpadDown || SDL_JoystickGetAxis(joy, 1) > 8192) bot=1;

Hi,
what does it mean quit/starting uae4all..
if i'm in console it isn't closed?

after i compile
sudo ./retropie_packages.sh uae4all build
it says
collect2: error: ld returned 1 exit status
Makefile.pi:174: recipe for target 'uae4all' failed
make: *** [uae4all] Error 1
/home/pi/RetroPie-Setup
Could not successfully build Amiga emulator UAE4ALL (/home/pi/RetroPie-Setup/tmp/build/uae4all/ua4all not found)

i try to start uae4all and doesn't work .. is it possible having a package or file working to put in the sd?
Thks a lot

@magoburicchio I would love to be able to change the UAE4ALL configuration, some games just don't play well with keyboard. I was curious, did you ever get it to compile and run properly?

Thanks!

@Goosebuster hey. I got it to complie and work but i only changed it to set up the dead zone for the analog stick and so far all the games i have tired have worked fine
