Mayflash n64 Controller Slow Joystick

[doakey3]

I am using a mayflash n64 adapter with retropie 3.0 beta 4 for raspberry pi 2:

I have edited
/opt/retropie/configs/n64/retroarch.cfg
in order to create specific controls for the mupen64plus emulator (including hotlinks)

When I start Ocarina of Time in mupen64plus, all of my controls work, but when I push the joystick through it’s full range, link walks instead running. I have seen other threads where advice is given to edit
/opt/retropie/configs/n64/InputAutoCfg.ini

however, this file already contains a controller called [Linux: USB GamePad] and changing the AnalogPeak and AnalogDeadzone for my controller has no effect on the game (I don’t think the file is being used…). I don’t want auto controls anyway, I want to use the controls I have outlined in /opt/retropie/configs/n64/retroarch.cfg

I’ve also tried editing the ‘AnalogPeak’ value in /opt/retropie/configs/n64/mupen64plus.cfg but that hasn’t changed anything either.

Is there a way to adjust the joystick range for my mayflash n64 adapter? How can I make link run?

As a side note, I had this same problem with project64 on my pc, but in the controls window, there is an option to uncheck “Real N64 Range” and that fixed the problem entirely.

I have been at this for hours. Any help would be greatly appreciated.

I fixed this issue by typing

jstest /dev/input/js0 I observed the values of the joypads as I pushed them. I pressed ctrl+c to exit that and typed:

jscal -c /dev/input/js0

This allowed me to recalibrate the controller’s joypads. I ran

jstest /dev/input/js0

again and saw that the values had changed. I went to /opt/retropie/configs/all/retroarch.cfg
and edited the line:
input_autodetect_enable = true
and I changed it to false
For good measure I deleted my joypad’s auto config file by going to
/opt/retropie/configs/all/retroarch-joypads
and removed all files there.

I then went to
/opt/retropie/configs/n64
and edited the retroarch.cfg file there.

#include "/opt/retropie/configs/all/retroarch.cfg"
fast_forward_ratio = "2.0"

input_joypad_driver = "linuxraw"
input_device_p1 = "0"
input_player1_joypad_index = 1
input_player1_b_btn = 2
input_player1_a_btn = 1
input_player1_up_btn = 12
input_player1_down_btn = 14
input_player1_right_btn = 13
input_player1_left_btn = 15
input_player1_start_btn = 9
input_player1_select_btn = 8
input_player1_l2_btn = 8
input_player1_r2_btn = 7
input_player1_l_btn = 6
input_player1_r_y_plus_axis = +2
input_player1_r_y_minus_axis = -2
input_player1_r_x_plus_axis = +3
input_player1_r_x_minus_axis = -3
input_player1_l_y_plus_axis = +1
input_player1_l_y_minus_axis = -1
input_player1_l_x_plus_axis = +0
input_player1_l_x_minus_axis = -0 

input_enable_hotkey_btn = 14
input_exit_emulator_btn = 9
input_load_state_btn = 7
input_save_state_btn = 6

The important part about this file is to specify that you want the joypad driver to be “linuxraw”.

After doing this, link was able to run and I had no problems with the controls. Unfortunately, the joystick calibration will be undone at reboot.

You can use jscal -p to read the calibration settings.

Then call the function

jscal -s 1,6,128…..(a bunch of numbers) /dev/input/js0

ideally, you would have a script run at startup that would call this function for you, but I haven’t made it that far yet.

ok, with your controller plugged in type

lsusb

(That’s a lower cased ‘L’ by the way) This should give you the device info for your controller. for me there was a line that said,

Bus 001 Device 005: ID 0e8f:3013 GreenAsia Inc.

make a file by doing
sudo nano /etc/udev/rules.d/60-n64.rules

in that file put:

ATTRS{idVendor}==”0e8f”, ATTRS{idProduct}==”3013″, RUN+=”/opt/retropie/configs/n64/n64-config.sh”

replace the 0e8f and the 3013 for your device

now do

sudo nano /opt/retropie/configs/n64/n64-config.sh

and put:

#!/bin/bash
sleep 1
jscal -s 6,1,0,128,128,6882750,6627834,1,0,127,127,6882750,6795627,1,0,128,128,5592235,5592235,1,0,128,128,5592235,5592235,1,0,0,0,2147483647,2147483647,1,0,0,0,2147483647,2147483647 /dev/input/js0
jscal -s 6,1,0,128,128,6882750,6627834,1,0,127,127,6882750,6795627,1,0,128,128,5592235,5592235,1,0,128,128,5592235,5592235,1,0,0,0,2147483647,2147483647,1,0,0,0,2147483647,2147483647 /dev/input/js1

Now make that file an executable by doing:

sudo chmod 755 /opt/retropie/configs/n64/n64-config.sh

Now every time you plug in the controller, that script will be run and your joysticks will be recalibrated.

One gotcha is that the files need to be in unix format. I was writing the files on my windows pc and copying them over and ran into problems. To solve this I downloaded dos2unix for windows and converted them that way.
