It requires the shareware version of Doom on the ’s Note: DirectX 9.0c, once known as the CORE of the Windows “technology-driven force” which was behind HD multimedia and video games, developed for the said OS. The RAD version of Doom is also available on frntc's GitHub with simple instructions to start playing. (German) offers pre-built units for around 20€. Building requires a 3D printer for some components. The device, which supports the Commodore 64 and 128, comes in two interchangeable variants: one based on Raspberry Pi 3A+/3B+ dimensions and another patterned after the Raspberry Pi Zero 2.
The Super NES version of Doom utilizes the SuperFX chip, which was most famous for enabling the console to render 3D polygons in the original Star Fox.Ĭurious users can buy or build RAD cartridges through frntc's instructions. The C64 converts the frame buffer to bring an image to the display, handles input through its keyboard and mouse, and pushes impressive 22050Hz sample audio through its SID chip.Įxpansion chips that enhance a platform's basic capabilities were fairly prolific for computers and game consoles in the 80s and 90s. Made for PAL CRTs, it runs at a smooth 50fps - significantly faster than the original DOS-booted game.īased on a Raspberry Pi, the expansion cartridge does most of the legwork, bypassing the Commodore's CPU in favor of the RP's ARM processor.
The hobbyist's system uses a copy of Doom that looks similar to the DOS version's low-detail mode running in 320x200 resolution. Despite the required SuperCPU upgrade, it runs with degraded colors at a barely playable framerate due to its complete lack of optimization around the old hardware.Ĭomparing the version on frntc's RAD Expansion Unit reveals a night-and-day difference. Technically, there is already a Linux-based Commodore Doom port. What better way to test the device than by getting it to play Doom? Modder "frntc" recently unveiled an expansion cartridge for the Commodore 64 that lets the iconic home computer and its relatives operate software once thought unimaginable for the 8-bit platform.
The mod includes instructions, so Commodore owners can set up the demo and run other Raspberry-enhanced software for themselves. The effort utilizes a Raspberry-based attachment to run the game surprisingly well in a way neither piece of hardware could do alone. In brief: Hobbyists will try to run Doom on anything, but a new Commodore 64 conversion is unique.
