Chris Hackman had a dream rising up within the late Nineteen Nineties that was shared by numerous different players: a Game Boy Color that may very well be worn like a watch. He by no means imagined it could occur, but right here we’re, and it’s known as the Time Frog Colour, his newest undertaking.
The Time Frog Colour runs the entire identical video games as the unique Sport Boy Colour, however with out the necessity for emulation. Chris Hackman has earlier expertise with a majority of these tasks, having labored on FrogBoy in 2023, which successfully rebuilt your complete Sport Boy Colour {hardware} from scratch. So all of it begins with the unique Sharp system-on-chip, which drives the Sport Boy Colour and includes a Z80 CPU core. The place issues received actually powerful was with the show output; principally, the processor sends out parallel RGB alerts that don’t match up with the panels we’ve all grown accustomed to as of late.
Chris created a system that included an RP2040 microprocessor, which is actually a compact however highly effective Raspberry Pi board in a tiny field. He manipulates the sign in actual time utilizing the programmable enter/output pins. Consider it as a bit translator that permits the video to play seamlessly on the brand new display screen. So, as soon as he received the show found out, the Time Frog Color is extremely slim, measuring solely 38 millimeters large and 15 millimeters thick, skinny sufficient to put on whereas but permitting for the controls and gaming slot.
The case is machined from 7075 + 6061 aluminum and anodized in a deep purple that resembles earlier Nintendo colorways. The buttons are on the edges reasonably than the entrance, with 4 motion buttons on one edge and a small directional pad on the opposite. Each has a practical tactile swap hidden inside a 3D printed cap or a machined bit with a silicone cowl to offer it an actual really feel.
Chris needed to get imaginative as a result of Sport Boy cartridges are just too giant to suit into one thing so compact. He created customized PCBs that seem like Sport Boy cartridges however connect with a novel M.2 connector contained in the Time Frog Colour. These ones, nevertheless, solely do one factor: learn the flash reminiscence that has been loaded with the suitable ROM information. One of the well-liked video games even options an MBC3 flash cartridge design. All the system is powered by a battery disguised beneath the watch strap, and the strap itself is a versatile circuit board that connects the strap to the principle physique, with a USB-C connection on the facet for charging.
The entire energy system should be able to switching between voltages starting from 1.1 to five volts. Area was fairly restricted right here, so we needed to make just a few compromises. The parts ate up the entire additional house, leaving no capability for a speaker, due to this fact this model of the watch has no audio wolfed all. Consequently, the battery life will probably be drastically decreased when in comparison with a standard smartwatch, because the outdated authentic {hardware} consumes energy far quicker than newer electronics. Even with a shorter battery life, the watch will proceed to tick and protect correct time when turned off.
The gameplay feels exactly prefer it did within the good outdated days for the reason that silicon inside continues to be functioning precisely as Nintendo supposed. That’s not stunning given that almost all of the unique code continues to be current, buzzing alongside simply because it did within the 8-bit interval. Hackmann has said that he’ll finally submit the entire designs on GitHub, however he’ll hold all of them beneath the LeggoMyFroggo moniker.
