The PiTrex cartridge replaces the CPU of the Vectrex video game console with the modern processing power of a Raspberry Pi Zero single-board computer. With an ARM CPU running at 1GHz and 512MB of RAM, this system is capable of emulating vintage vector arcade games. It also provides an easier, and much more powerful, environment for developing new games. Plus it can run Vectrex game ROMs loaded onto the Pi's MicroSD card akin to a multicart, by running a modified version of the VecX emulator.

Needed

• Raspberry Pi Zero: The "Raspberry Pi Zero WH" is the recommended model. A "Raspberry Pi Zero W" will also work but requires a pin header to be soldered on, and a "Raspberry Pi Zero" also lacks wireless support (wireless/networking/Bluetooth functionality is currently only supported in the Linux environment, and work on the related software is not yet finished). These can be purchased from suppliers worldwide, see the Raspberry Pi website for official suppliers (note: currently doesn't mention the Raspberry Pi Zero WH, though it is available from many suppliers who offer other Pi Zero models). The new "Raspberry Pi Zero 2 W" is now supported but does not improve performance.
• MicroSD card: Recommended 256MB or larger. Cannot be larger than 256GB.
• Vectrex (any model)

This version of the PiTrex board is functionally identical to the previous "developer release" with all the available software, see the wiki for a technical description of the (minor) changes. A high quality circuit board with hard-gold plated contacts is used to minimise wear from repeated insertions.

Open-source emulators and a couple of PC games have been ported for use with the PiTrex. Malban has packages that can be written to a MicroSD card and run most of the currently available software. Note that all current software is still in active development and bugs are still frequently encountered. Work is in progress to port other games and emulators.

Highlights of the games currently available include fully-featured Asteroids, Tailgunner, Battlezone arcade emulators (MAME-compatible ROMs required), Vectrex emulation with "speedy" mode, game save support, and customised Vectorblade emulator, as well as ported open-source games ZBlast and Hyperoid. GS BASIC from the Vectrex 32 project is now supported, along with existing games for that platform such as VxTRON. Tens of additional arcade emulators are playable, though unrefined and mostly without sound.

PiTrex is an open-source project documented at the PiTrex Wiki and with code hosted at GitHub. Getting started with the PiTrex.

The PiTrex is available in a customised Vectrex cartridge case, or without. Files to 3D print a case are available for download and at Thingiverse.
