GameBoy Analog Meter

Boring game.

Here’s an interesting setup using a GameBoy Advance as an interface and power supply for a PIC microprocessor. He’s got the PIC connected to the serial port of the GameBoy Advance and is able to pass and retrieve data for display on the screen. You can see above that he is showing two analog values from the pic. You can download the schematic and source code and see a few more pictures, but that’s about it.

LEDboy Super Pixel Brothers

We really love this version of super mario brothers that [Brad] is putting together. It is played on an 8×8 RGB LED screen, powered by a pic microprocessor. There aren’t many details on the construction or code yet, but we expect he’ll publish it soon. We’re guessing it is very similar to his other 8×8 game system. If you really want to get a jump start, he has published some great tutorials on working with pic microprocessors.

Gameboy Color boot ROM

It’s only been a week since the Super Gameboy’s boot ROM was dumped by [Costis] and he’s already at it again. This time he’s managed to grab the Gameboy Color’s boot ROM. He found the newer Gameboy Color’s hardware is able to cope with a clock speed up to 100MHz, so the original clock increase trick he used on the Super Gameboy wouldn’t work again.

Instead he discovered a quick disconnection of clock and power before 0xFF50 would make the Gameboy jump to a random area within the ROM. Then it was only a matter of entropy, luck, and some special NOP instructions until eventually he had the boot ROM. Keep up the good work [Costis].

Gameboy foot controller

[Joey] sent us a link to the newest version of his Gameboy foot controller. In the video above, you can see how he uses it to control the loops in the background while he plays his guitar through an 8-bit filter. That is an old video, using the previous version. He tells us that several gameboys were used in the construction. At one point, he had to replace the guts because the music was so loud it knocked his equipment over and destroyed it. We can’t help but feel just a tiny bit of excitement as memories of renting a NES cartridge for the weekend fill our heads when we hear these riffs. His music isn’t too bad either. There is a growing crowd of people that support “chip music”. You can see what looks like a decent sized gathering enjoying a show with a little bit of a history lesson after the break.

[This video, and the original version of the controler were posted about a year ago, good catch commenters]

USB gameboy cart

gamecart

[Jose Torres] sent in his latest attempt at creating a custom Gameboy game cartridge. We’ve featured his projects before, and he’s come a lot closer over the last 2 years. He’s aiming to create an easy interface for homebrewers that doesn’t require any other special equipment. In this revision, he’s using a PIC and a memory controller to interface between an SD card and the Gameboy. The cart also has USB support for uploading files to the SD card and reprogramming the PIC. Because it’s just USB mass storage, it will work on almost any modern OS. He’s currently testing the device, but hopes to be selling them soon for $40.

Happy birthday Gameboy

In honor of Gameboy’s 20th birthday, Stupidinventions has released a video showing how to replace the screen. They tend to be a common weak point. Essentially, they just bought another , we’re assuming broken, Gameboy and swapped them out. Not a horribly complicated hack, but nice to know that it’s so easy. We have fond memories of the Gameboy, which came flooding back when he blew in the cartridge.¬† Happy Birthday Gameboy.

Game Boy Pocket backlight

gameboy

[palmertech] and [Bibin] have both completed backlight projects for the Game Boy Pocket recently. The most difficult part of the transplant is carefully removing the reflective backing on the LCD. After a thorough cleaning, a diffuser and backlight panel were added. [palmertech] used a backlight salvaged from a DS, while [Bibin] built his own using LEDs. You can see his backlight in the video embedded below. There’s a disassembly video too.
