    Discussion PSA: Be very, very careful if you decide to delid the GPU of a 6-layer board...

    Even with the use of soft materials like cotton swabs, microfibre cloths, isopropanol prep pads, and even dedicated glasses/lens cleaning wipes, I still managed to heavily scratch up the surfaces of the GPU dies... Weirdly enough I never was able to scratch the surface of the 4-layer GPU die...

    Discussion Delidded the Wii CPU and GPU

    Eh I mostly did it because I wanted to look at the silicon under a microscope. I’m amazed at how they managed to fit essentially an iMac G3 in such a small package, but I guess it shouldn’t be a surprise now since we have smaller and more powerful ARM CPUs. So no iMac G3 on an FPGA either? damn

    Discussion Delidded the Wii CPU and GPU

    Huh, check this out. There seems to be a little pinkish discolouration on the CPU die. Not sure if this is because I turned it on for about a minute or so to make sure everything works before I trim the PCB (which it does fortunately), but I’m curious as to what this is.

    Discussion Delidded the Wii CPU and GPU

    Yeah the SNES uses a modified version of the 16 bit modification of the 6502 which is already a modification of the Motorola 6800 (Two zeros, not three) so it is a bit of an oddball, although a company called Analogue sells FPGA-based SNESes that they claim are engineered with maximum...

    Discussion Delidded the Wii CPU and GPU

    Well I heard of a GitHub project called MiSTer which uses an FPGA board to emulate old systems based on the Motorola 68000, primary Atari ST, Amiga, and several arcade boards. Hell there’s an FPGA-based Amiga called the Vampire4 whose “68000” processor outperforms any real 68k ever made. But...

    Discussion Delidded the Wii CPU and GPU

    Was interested in getting a shot of the silicon underneath the heat spreaders, and potentially improving thermals, so I took a razor blade, an old credit card, and a huge leap of faith, and was able to pop both of them off and get a nice gander at the silicon. Admitted there is a bit of...

    Question First time trimming, have both a CPU-01 and CPU-40 revision Wiis

    I was wanting to use a WiiMote with Wii Sports and Super Mario Galaxy, so I guess I'm up for the challenge. Probably will have to add a couple of infrared lights so the WiiMote cursor can show up.

    BitBuilt Welcome Thread!

    I was thinking of taking a look at the silicon with a microscope and possibly reverse engineering the chip. I have my work cut out for that though.

    Question First time trimming, have both a CPU-01 and CPU-40 revision Wiis

    Heya, quarantine got me bored asf and I grew up on the Wii/GC both so I'm interested in making a portable. Blame my utter daftness and idiocy for overlooking the warning not to use a SanDisk USB drive. Well, I was able to use it to install BBLoader, however it got stuck on "exitting" after...

    BitBuilt Welcome Thread!

    Hi! Came here from Linus Tech Tips' video on making a portable Wii. That and the GameCube were my childhood. Since I'm studying computer engineering, I thought it would be a fruitful waste of my time and money to build a portable Wii and learn skills like using a multimeter and soldering iron...
