8bitdo N64 Controller - Odroid XU4

destruct_icon

Out of spite of the Nintendo Classic being unavailable, picked up an odroid xu4 and discovered how wonderful this project is. Thanks so much to everyone who has been contributing!

Bought an 8bitdo N64 Controller:

Was wondering if anyone was able to pick up one of these and get it to fully work on Batocera/mupen64. The following mapping is VERY close (i've only used it plugged directly in):

Batocera Mapping - Controller - Notes

Up - Dpad Up - Works
Down - Dpad Down - Works
Left - Dpad Left - Works
Right - Dpad Right - Works
Joy1 Up - Joystick Up - Works
Joy1 Left - Joystick Left - Works
Joy2 Up - C-Up -- Tries to press both Cup and Cdown at the same time. Maybe mapped to 2 buttons?
Joy2 Left - C-Left - Works
A - C-Right - Works
B - A - Works
X - C-Down -- does not function
Y - B - Works
Start - Start - Works
Select - Skip - NA
L - L - Works
R - R - Works
L2 - Z - Works

^ This still allows you to play a majority of games without much hindrance cause c is mostly for camera. Few games still require c access though.

I was looking into files such as /recalbox/scripts/generateEmuConfigs/createMupen64Config.sh which appears to configure the inputs and then Checked against /recalbox/share/system/configs/mupen64/InputAutoCfg.ini which confirms the double button push on C-Up.

C Button D = button(3)
C Button L = button(4)
C Button R = button(9) button(4)
C Button U = button(3) button(8)

Ran the sdl-jstest against the controller and found the button#s match up.

0: 0 [ ] --- A
1: 0 [ ] --- B
2: 0 [ ]
3: 0 [ ] --- CDown
4: 0 [ ] --- CLeft
5: 0 [ ]
6: 0 [ ] --- L
7: 0 [ ] --- R
8: 0 [ ] --- CUp
9: 0 [ ] --- CRight
10: 0 [ ] --- Z
11: 0 [ ] --- Start

I'm guessing i may have to manually modify the input config script and force the correct buttons/inputs? I've had some difficulty remounting / to poke around the FS and py/sh scripts. If anyone has any input, please let me know.

destruct_icon Does this link help (in terms of remapping the controls for N64 emulators?)

destruct_icon So after hours of tinkering with my own 8BITDO N64 controller I finally got it working, and it was way simpler than I expected. I actually did this on a Chromebook. Make sure your controllers are all paired first.

All you have to do is access the RECALBOX share on your wifi network (make sure your computer is set to view hidden system files) and then change two files as follows:

1) Share > System > Configs > Mupen64 > input.xml

2) Share > System > .Emulationstation > es_input.cfg (only edit N64 gamepad section)

<inputConfig type="joystick" deviceName="8Bitdo N64 GamePad" deviceGUID="05000000c82d00003038000000010000">
	<input name="a" type="button" id="3" value="1" code="304" />
	<input name="b" type="button" id="0" value="1" code="305" />
	<input name="down" type="hat" id="0" value="4" code="16" />
	<input name="hotkey" type="button" id="6" value="1" code="310" />
	<input name="joystick1left" type="axis" id="0" value="-1" code="0" />
	<input name="joystick1up" type="axis" id="1" value="-1" code="1" />
	<input name="customcright" type="button" id="9" value="1" code="313" />
	<input name="customcup" type="button" id="8" value="1" code="5" />
	<input name="l2" type="button" id="10" value="1" code="314" />
	<input name="left" type="hat" id="0" value="8" code="16" />
	<input name="pagedown" type="button" id="7" value="1" code="311" />
	<input name="pageup" type="button" id="6" value="1" code="310" />
	<input name="right" type="hat" id="0" value="2" code="16" />
	<input name="start" type="button" id="11" value="1" code="315" />
	<input name="up" type="hat" id="0" value="1" code="16" />
	<input name="x" type="button" id="4" value="1" code="307" />
	<input name="y" type="button" id="1" value="1" code="308" />
</inputConfig>

@destruct_icon perhaps you're looking to
https://batocera-linux.xorhub.com/wiki/doku.php?id=en:diagnose_joysticks_issues

the n64 mapping is automatically done via /usr/lib/python2.7/site-packages/configgen/generator
https://github.com/nadenislamarre/recalbox-configgen/blob/batocera-5.X/configgen/generators/mupen/mupenControllers.py

there is possibly an error on this script.

Hello,

i want to edit the file "InputAutoCfg.ini" for config my N64 USB-Controller
like this: https://github.com/recalbox/recalbox-os/wiki/Configure-N64-controllers-(EN)
but files read-only and can't edit to write?

Config with recalbox es menu won't work with N64 controller

nadenislamarre

on xu4, system files are not modifiable ;-(
but what do you want to do exactly. If that's a modification that may serve everybody, maybe i could add it to the system.

kuki3112

the operation of ES is with N64 controller different than the control in the N64 emulator,
even if I play snes with the n64 controller, i need a different configuration.

At the default configuration when you press start on N64 controller, you return to the ES.

how to access retroarch menu?

i think, N64 Controller ist not the best for recalbox or batocera,
unfortunately it is the best for N64-Games like Mario Kart 64 or Goldeneye 007

nadenislamarre

on the n64 emulator, retroarch is not used. it's mupen64.
there is no menu.

I was also curious about how to setup controllers to use with the N64 emulator. Anyway a modification can be added to allow Mayflash N64 Controller Adapters to be recognized and configured properly for the N64? Additionally, is there a chance the default screen ratio can be changed to a widescreen format?

I also have the XU4, and thanks to this post, I now understand why none of my changes to the config files have worked so far.

Thanks,
Sean

nadenislamarre

you can change the screen ratio in options, but i don't know if its considered on the n64.

I also recommend to make these specific configurations directly in the retrocarch setup

Has any progress been made on this? I wasn't able to make any progress in mapping my 8Bitdo N64 controller correctly either because of read-only system files. It would be greatly appreciated if either custom mapping was made available for XU4 OR if someone added the configuration detailed here to the next build:

I just bought a INNEX N64 wired controller and tried to map it like in this thread:
https://forum.recalbox.com/topic/12106/usb-n64-controller-mapping
but it failed. Seems as if the config is overwritten/overruled by something else. even changes directly in retroarch had no effect. Additionally the mapping within retroarch is very confusing since it mentions many buttons, that are not on the real controller and vice versa some are missing (two of the c-buttons for example)
