Hi,

Seems there was a hardware revision of KunaiGC and the BOM was partially updated.

There is still a reference to R5 which does not exist anymore :)

good morning

I am trying to debug an install and had few questions

1 - please check this continuity map. the colors are a bit hard to see so I numbered them. point 2 does not seem to connect anyplace in the source picture.

2 - do all the points have to be soldered, or just the ones with soldering points.

3 - is there a guide for the flashing lights? how do we use these do check an install?

thank you

I’ve installed the KunaiGC chip, had run a game through Swiss and everything. I was playing with the settings but changing them back and then suddenly I don’t have video output anymore. I got scared that I might have shorted my KunaiGC chip as I did not cover the pins in the back. I opened my GC and I noticed that the KunaiGC chip doesn’t blink the LED lights like it did at the initial boot. I desoldered it to check the pins in the back and attached is a picture of them. If the pins look fine, is it normal for the board to not blink the LED lights anymore? I want to make sure my problem is not the chip and hopefully just my HDMI converter not being strong enough.

Pcb way sent me this

I have lost my qsb and decided to wire the kunai to the ipl with 30. Gauge wire...but that 7th pad that isn't marked on the test page with no color isn't marked....where do the wires go...no diagram and the only 3 videos of the install don't talk about it

Can't find the Gerber file to download

See subject, want to be able to boot into Swiss on powering on the gamecube by default. Didn't see an option that jumped out to me that would do that, does one exists and if not, can it be added in future?

There has been a new release of KunaiLoader, but binary only. Is source code update planned ?

On the wiki page (https://github.com/KunaiGC/KunaiGC/wiki/Build-the-KunaiGC), 2 types of resistor are needed : 1 x 10k ohm, and 3 x 220 ohm, but, on the schematic, there are 1x 10k ohm, 1 x 100 ohm, and 2 x 470 ohm.

I guess the good values are the one on the schematic ?

Hello. I've been trying to update my KunaiGC to the latest KunaiLoader/KunaiMenu version but the wiki page is unclear on a few things.

Firstly, it said to add files to the KUNAIGC folder but there's no indication on where that folder should reside (I'm assuming on the root of SD card).

Secondly, there's no information on comparing versions of the apps. My menu looks different than the screenshot, so I'm guessing I have the old version. But even the screenshot it unclear, the wiki page mentions KunaiLoader v1.1 but the screenshot shows KunaiUpdate v1.0. It's all very confusing.

Anyway here's what I attempted: Following the "Updating the Loader to Version 1.1 or higher" section, I placed two copies of KunaiLoader.dol from the latest release into KUNAIGC folder on SD card (it's formatted using FAT32 and I'm using SD2SP2) and I renamed one to recovery.dol. I put the SD2SP2 with SC card back into GameCube and powered on while holding Z. I just get the same old menu screen with no update process being kicked off. What am I doing wrong?

Hi,

I've currently built a few KunaiGCs and am ready to perform the flashing steps. The CPLD seems straghtforward, although I am not sure which jedec file I should be using to flash, as that is not mentioned in the wiki. The only IPL .jed file that I could find for the xc9536 was one bundled with the Shuriken Attack. Will this do the job for providing a basic IPL or should I be using something else?

I guess the wiki page on programming the flash memory is incomplete--I noticed the labels on the Raspberry Pi GPIO pins don't correspond to the SPI SOICbite pinouts exactly. Some clarification here would be helpful. I think the appropriate .bin file for the
16Mx8 flash IC is KunaiGC_lfs_16M.bin.

Thank you

The wiki mentions the SOICbite-Interface to program the memory and the CPLD, but the latest version of the pcb seems to use another type of interface.
Is it possible to update the Wiki?

Hi,

After finally having build my prototype of KunaiGC I had in mind to program the XC9536XL with the gc_ipl.jed file but I see that this needs to be generated with xc3sprog and the vhdl and udf files present on KunaiGC-ipl repository.

I am using ISE Impact 14.7 win64 and have downloaded xc3sprog binaries for the same platform but after reviewing the makefile I see that the target part is XC9572XL-10-VQ44. Why? Shouldn't it be XC9536XL?

As calling the gc_ipl makefile does not seem doable with win64 I was considering generating the .jed with Xilinx ISE having already the .vhd and .ucf, but this is something new for me.

Wouldn't it be possible to include the .jed file in the gc_ipl repo?
That will make things easier for those who won't use a rpi3/linux.

Thank you

Hi,

What PCB thickness do you recommend when ordering the QSB and main board?

Thanks

Hi, I installed my KunaiGC chip and got full continuity and even the proper lights to make sure it was working (flash on 1 then light on 2). Then when I tested the console I found that none of the button combos were doing anything. Start didn't boot swiss, z didn't boot KunaiRecovery, D-Pad Down didn't enter debugging mode, I got nothing. I used an OEM controller and tested using the LazerBear internal BlueRetro controller ports and the original/stock ports. It's almost like it isn't installed at all.

I don't see the license listed in the repository or nested in the folders.

Hi, I was little confused on the recommended resistor values. In the PCB schematic it says R1 is 100ohm and R3 and R4 is 470ohm. In the wiki section it says to use 220ohm for all three. Then the boards being sold by consoles4you are using 22ohm for R1 and 220ohm for R3 and R4. Thanks!

I've placed the latest version of Swiss on my SD2SP2, on the root of the SD card named start.dol, however when I hold start at bootup, it still boots the older onboard version of Swiss. Anything I should be doing differently?

Alternatively, is there any way to update the on board Swiss? It kinda defeat the benefit of this mod if it can't be updated.
