Viper GC

[RazorX2014]

Hi guys.


Ive a GAMECUBE with a viper extreme and cobra bios 2.1 in it but i dunno how to flash with success Swiss.
Ive tried to make a cobra vgc+swiss dol (the firmware was about 1mb) without success
seeing these steps:

(Open a DOS prompt. The syntax is “copy /b cobra21.vgc+plugin.cbp output.vgc”.
Make sure that cobra21.vgc is 81920 bytes long before the copy operation.)

The flashing seems ok, but when i turn on the gamecube, it loads the original bios.
Can someone help me,please?

there is also software you can use, like this:


in the swiss zip you want to use the one under 'DOL\Viper', the latest verison is 'swiss_r1622-lz-viper.dol' but i highly recommend you just flash the viper extreme modchip with iplboot like i did and that will boot swiss directly from something like the sd2sp2 when named ipl.dol.
that way it's super easy to keep it upto date.

ive sd2sp2.
So i put "swiss_r1622-lz-viper.dol" naming as "ipl.dol".
But where do i find the right IPLBOOT for my EUR Gamecube 001?

you need to first flash the iplboot bios to your viper extreme which will overwrite it's bios.
you can get it here:
https://github.com/redolution/gekkoboot/releases
once it's flashed onto the viper extreme then you add the normal swiss dol to the sd2sp2's sd card on the root and name it ipl.dol, once you've done that your gamecube should just boot directly into swiss on startup.

Thank you. I will try and let you know...

Ive tried but at the boot it starts the iplbios.
Doesnt start swiss. do you think its a problem of microsd? Ive formatted it in FAT 32...
Or its a problem of the reader?

make sure it's the normal swiss dol (swiss_r1622.dol) renamed to ipl.dol on the root of a fat32 micro sd card plugged into the sd2sp2

As a thank you for all the help I received here, a small write-up of the solution for my question regarding "booting to Swiss using a ViperGC without the need for a disc":

1. Download the latest release of iplboot (currently r9.1), extract the .zip file and flash iplboot.vgc to your ViperGC (replacing the original Cobra OS)
2. Download the latest release of Swiss and copy the swiss_rXXXX.dol (currently the latest release is swiss_r1668.dol) to the root of your SD-card for the SD2SP2
3. Rename swiss_rXXXX.dol to ipl.dol
Optional 4a. Download the Game Boy Interface, extract and copy gbi.dol (under \apps\gbi\ ) to the root of your SD-card for the SD2SP2 (more info regarding the Game Boy Interface can be found here)
Optional 4b. Rename gbi.dol to a.dol (or to your choosing to b.dol / x.dol / y.dol / z.dol or start.dol)

The following will happen:
- Normal boot (just power on the Gamecube): Swiss will boot from the SD2SP2
- Power on while holding D-pad Left: the original Gamecube intro (IPL) will start
- (Optional) Power-on while holding the A-button: the Game Boy Interface will boot from the SD2SP2

Alternatively, if you like to keep the Cobra functionality while still being able to boot to Swiss without the need for a disc (but you'll need a SD-Gecko), you can use "SDLoad (Slot A & B)" as a plugin in Cobra OS and boot Swiss from the SD-Gecko in memory slot A or B. (Afterwards you can still load content from the SD2SP2.)

yes, this works but what would be nicer is keeping the cobra bios functionalities as it has sentimental value for me

1/ having iplboot reduced to fit as viper plugin on the flash
2/ having iplboot on memcard boot.dol with a viper plugin triggering the boot.gci

who can pull it off?
