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].
[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.
[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.
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.
[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.
Here is a video of a GameBoy Color being played on an LED matrix. He has built it up to 140×140 LEDs so far and it seems to be going well. He needs to add the final 20 LEDs to get the 160×140 resolution of the GameBoy. He notes in the comments that he had some problems with dead LEDs in the boards he got from eBay. Trying to remove the dead LED with a hot air rework station resulted in massive damage to the board. At one point he says that the power consumption is 1KW when showing all white. Wow, that’s a drain.
[Kevtris] gave us some more info in the comments with a link to the build pictures in his blog.
[Mark] had a broken TI-83 graphing calculator and an overwhelming urge to play Pokemon in math class. The solution to his predicament, obviously, is to hack a GameBoy color into the body of his TI-83. He gutted the calculator and connected the front buttons to the contacts on the GameBoy. After some cramming and taping bits together, he got it all working. Now he just needs to find a way to make the cartridge a little bit less conspicuous.
For roughly $250, you too can have this sweet bit of gadgetry based off of the Arduino platform. It is open source, and has some pretty impressive specs. Sporting a rumble pack, lithium ion battery, OLED display, and space for expanson. You can buy the pieces pre assembled, or as a kit. If you get the kit, you’ll see that the controller board has been laid out so that you can solder your buttons and joystick in as either left handed or right handed. The only problem? No games yet.
[Bacteria] sent us this sweet video of the Multi Platform Plug’n'Play system running his new GameBoy Advance module. He’s made an addon for his unit that allows him to play his GameBoy Advance cartridges as well as GameBoy ones. Watch the vid for the details and some views of the insides.
Reader [John Grayson], known for his multiconsole portable, has constructed a brand new portable. Not liking the controls or the tethered nature of retro TV games he decided to build a modular portable system. He built a custom system that uses cartridges created from TV game systems. The device has a 5.4″ screen and two Canon batteries for 4.5 hours of play.
