Arduboy at the Giant Display

We’re large lovers of the Arduboy right here at, however we’ll admit its tiny display isn’t precisely best for lengthy gaming classes. There are some DIY builds of the open supply hand held that use a bigger SPI OLED show, despite the fact that you’re moderately restricted on what sort of adjustments will also be made to the {hardware} earlier than the video games get started balking. However as [Nick Bild] displays along with his Arduboy house console, hacking the core gadget library opens up numerous fascinating probabilities.

Video games written for the Arduboy employ a commonplace library that handles the entire low-level {hardware} stuff, which incorporates a show() serve as to push the graphical knowledge out to an SPI-connected OLED show. What [Nick] has completed is re-write that serve as to as an alternative output to a customized VGA generator working at the TinyFPGA BX. He needed to delete reinforce for the Arduboy’s RGB LEDs as a result of he wanted the additional pins, however that shouldn’t reason a lot of an issue on the subject of tool reinforce.

(*1*)This does imply that video games wish to be recompiled towards the changed library to paintings on his {hardware}, however as nearly all of Arduboy tool is open supply anyway, that’s no longer a lot of an issue. We in particular just like the Tremendous Sport Boy taste border  you get across the show at no additional price.

At this level the {hardware} appears much less like a console and extra like a breadboard full of jumpers, so we’re taken with seeing this mission taken to its logical conclusion. A customized PCB, enclosure, and perhaps even reinforce for the use of the unique NES controllers would flip this into right kind gadget worthy of any hacker’s sport room. You should even put the video games on customized cartridges when you sought after, despite the fact that a flash chip that holds the gadget’s complete library could be somewhat slightly extra handy.
