Modding with Wiifree/Wiiskas/Yaosm
-PIC microcontroller: 12F629, 12F675 or 12F683 (If you have a non-free email service, you get get FREE "samples" from microchip.com
example of 12F629:
-30 awg wire or wire of your choice
-8 pin socket (for external mounts)
Ok, well, first I will tackle the actual installation of the chip. For these chips they use the same installation schematic as the Wiinja.
Just solder those points up with your favorite wire. The numbered pads refer to what pin on the chip they connect to. Use the indent on the chip as a guide. From there you can either do a direct solder of the chip and keep it internal, or do some kind of external mount. Since they are releasing code for these chips constantly, I externally mounted mine. This way I can easily remove the chip to reprogram it with the newest code.
The wire just comes through a gap in the USB area. The chip socket is mounted on a piece of board which is stuck on there with really strong double sided tape (some people drill holes in their Wii to mount the socket. I'm not down with that ) When using a socket, make sure you wire it up correctly. It also has the indent that the chip has to make pin identification easier.
Now, for programming the chip. You will need a PIC programmer. You can get one of ebay for relatively cheap. Me being impatient did not want to wait, and being cheap, I made my own. There are wiring schematics all over, but this one is the simplest I have found.
Parts list:
-9 pin RS-232 Female connector
-22k resistor (1/4 or 1/2 watt)
-10k resistor (1/4 or 1/2 watt)
-2.2k resistor (1/4 or 1/2 watt)
-USB cable (using this to power the programmer
-BS 170 transistor (there's a substitute for this, but I can't remember what it is. Just search for it)
-8 pin socket
*Warning*: Some people say you do not need the transistor. You will need it if you want to reprogram the chip! You can program a chip once without it, but will not be able to update.
I used that to wire mine up. Works like a charm... not pretty, but it works...
After you have made/bought a programmer, you have to program it. Since there's already a nice guide for it here at Wii Xposed, I won't go into details on that.
There you have it. Now you can go with 2 different codes. There is Wiiskas which is at beta 1c right now, but does NOT have D2B support, or Wiifree which supports all chipsets and is CONSTANTLY being updated (twice yesterday and again last night while I was sleeping). Personally I use Wiiskas at the moment. I have a D2A NTSC Wii, and it works perfect for me. It has the speedfix and plays all my backups no problem. Wiifree is still working some bugs out at the moment, but I will soon be switching to Wiifree 100% sometime soon because of the support for it.
Hope this helps.
