Fix Up/Left joystick direction for THT 2P arcade controller with device ID 0x75e1

zhaoyun

So the OP's patch added his own device id on top of the 0x05e1, while I manually replaced 0x05e1 with my 0x05e0. I do not think it makes any difference as I do not have a 0x05e1 device. The compile process completed without warning and I can see the timestamp of modules installed are updated, so I presume the compile succeeded.

Do you have any idea why the up/left still fail the evtest?

stuntstein

Perhaps you'll need to reset the RPI input configuration. Something like:
Manage Packages -> Core Packages -> emulationstation -> Configuration or
Configuration / Tools -> emulationstation
and choose the option to Clear/Reset Emulation Station input configuration
Thn reboot and see if RPI ask for input config at bootup.

@zhaoyun I just remembered something.

Here is what I did:

Made the quirks change
Manually typed in the changes in the three files, rather than patch:

hid_core.c added
{ HID_USB_DEVICE(USB_VENDOR_ID_XIN_MO, USB_DEVICE_ID_3H_DUAL_ARCADE) },

hid_core.h added
#define USB_DEVICE_ID_3H_DUAL_ARCADE 0x05e0

hid-xinmo.c added
{ HID_USB_DEVICE(USB_VENDOR_ID_XIN_MO, USB_DEVICE_ID_3H_DUAL_ARCADE) },

Went to follow the guide at https://www.raspberrypi.org/documentation/linux/kernel/building.md but with the following change:

Instead of

make -j4 zImage modules dtbs

Type

make -j4 zImage
make -j4 modules
make -j4 dtbs

I had found that trying to do all three on one line didn't actually work.

Then proceed with the rest:

sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm/boot/zImage /boot/$KERNEL.img

Then reboot.

OK I followed the patch kernel guide mentioned in my OP and have only performed a "make" and a "make modules". from what I understand, it should already include zImage and modules, not sure if dtbs is included. Anyway, I'll try to follow exactly the steps you mentioned to compile again. Let you know the result later.

stuntstein

If you didn't do below steps you never installed the new kernel. You have only compiled it.

sudo make modules_install
sudo cp arch/arm/boot/dts/.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm/boot/zImage /boot/$KERNEL.img

@stuntstein

I have done this already. I have even quit to the command and run both evtest and jstest and both cannot detect up/left motion. So I believe it is more likely a device/kernel matter rather than emulationstation config matter.

Yeah I have done "make install" and "make modules_install", but not the subsequent four lines of sudo cp. I assume make install at least do the zImage line, not sure if it also performed the dts lines.

stuntstein

Ok, it just sounded like you only did the make.
Can you check the build date of the running kernel to make sure that it is running yours?

I have forgotten most linux commands. Should I use "uname -a" to check build date?

Try it.
According to my master, Google, you should use uname -v for "kernel version information" :-)

At this point, I'd type in all three make -j4 lines. If they are current, it'll just say so and finish quickly. If not, then you are catching something that didn't compile.

The first time I tried this process, and put the three targets on one line after make, it resulted in a built kernel that was half and half... which I then copied over, and I had to wipe the SD card and start from scratch :)

I wouldn't follow the ithink.ch kernel building guide. I would follow the one at https://www.raspberrypi.org/documentation/linux/kernel/building.md

It took me several days to discover that the -j4 flag caused instability to my original version of pi which held up the compiling process, and it took me another couple of days to finally finish the compile. And I wish to update you that the pi can now recognise the joystick.

But the compiling really took a lot of time and I guess a lot of unnecessary modules were compiled. I am now trying to compile again using localmodconfig rather than bcmrpi_defconfig as the config set. I believe it takes much less time and still get the result.

Anyway, I think the emulator itself is another challenge, especially the mame. I totally don't know how the roms can be run. But this is another story......thanks everyone anyway.

Hi Zhaoyun,
Glad that you finally got it working. If you find a quicker way to build please let us know.
I was considering building on a more powerful linux machine but never found time to set it up.

@zhaoyun Hi man! I'm having the left up problem with a 05e0 controller and I was going to follow this guide
http://ithink.ch/blog/2013/09/08/patching_the_linux_kernel_to_install_the_xin-mo_dual_arcade_driver_on_a_raspberry_pi.html
then I wanted to search for more info and I saw that the patch in that guide is for 0x05e1. I saw that you could resolve the problem with 05e0 and if you could make me a guide or explain me how did you do that I would really appriciate. I don't know nothing about this things and I don't even know how to edit the patch to change to 05e0.
hope you see this and can help me cause you will really save me the day. thanks a lot.

@godsephiroth If you follow the instructions in my post here: https://retropie.org.uk/forum/topic/7832/fix-up-left-joystick-direction-for-tht-2p-arcade-controller-with-device-id-0x75e1/9 it should work for 05e0. The location in each file to make those edits is most easily found if you just

sudo nano <filename>
search for XIN_
add the line right after the existing entry
