Hands On With Mars FPGA A Powerhouse Development Board Tutorial

The MARS FPGA is an ambitious, open-source project designed to surpass the capabilities of existing FPGA-based retro gaming systems, particularly the MiSTer FPGA. This powerhouse development board promises a robust and versatile solution for retro gaming enthusiasts, but it also comes with a significant price tag and some controversy.

MARS FPGA Specifications

The MARS FPGA boasts an impressive array of specifications that make it a compelling choice for those seeking high-quality retro gaming experiences. Here are some key features:

4K Video Output: The MARS FPGA supports 4K video output at 4:4:4, providing a high-resolution display option for modern TVs and monitors.
Advanced Video Filters: It includes shadow mask and scanline filters, courtesy of Mike Chi from RetroTINK, enhancing the visual fidelity of classic games.
Multiple Video Outputs: The system supports high-quality analog video with options for RGBS, YPbPr, S-video, composite, and even JAMMA, catering to various display setups.
Powerful FPGA: The MARS FPGA uses an Efinix Titanium Ti180, a powerful FPGA that promises superior performance compared to the DE-10 Nano used in the MiSTer.

Hardware and Design

The MARS FPGA is housed in an injection-molded case, eliminating the need for DIY assembly. This design choice makes it more accessible to users who prefer a plug-and-play solution. Here are some additional hardware details:

ARM CPU: The system includes an ARM CPU, which will power the front end and potentially allow for running Linux and media playback.
Controller Modules: The MARS FPGA features snap-on controller modules, enabling compatibility with a wide range of OEM and aftermarket controllers.
MIDI Input/Output: For the enthusiasts, the MARS FPGA also includes MIDI input and output, a feature that will appeal to those who still use their MT-32 synthesizers.

Future Development and Compatibility

While the MARS FPGA is still in development, it has promising future prospects. Here are some upcoming features and compatibility:

Core Development: Support for Dreamcast, 3DO, and Atari Jaguar cores is on the horizon, although these will require development efforts from the community.
Linux Support: The inclusion of an ARM CPU opens the possibility of running Linux on the MARS FPGA, which could expand its functionality beyond gaming.

Pricing and Controversy

The MARS FPGA is expected to be a costly endeavor, with estimated prices around $700, not including shipping. This high price point has sparked controversy within the retro gaming community:

Cost Comparison: When considering the cost of a DE-10 Nano, analog output board, and other components needed for a MiSTer setup, the MARS FPGA might seem more reasonable, but it remains a significant investment.
Community Concerns: Some community members have expressed concerns about the MARS team's behavior and their perceived lack of support for the open-source MiSTer project. These concerns have led some to question the ethics and motivations behind the MARS FPGA project.

Practical Considerations for Potential Buyers

For those considering the MARS FPGA, here are some practical points to keep in mind:

Current Status: The project is nearing completion, but updates have been sporadic, leading to some skepticism about its release.
Community Support: The MARS FPGA's success will depend on community support and core development. Potential buyers should consider whether the community will actively develop and maintain cores for this system.
Alternative Options: The MiSTer FPGA remains a viable alternative, with a strong community and ongoing development. Buyers should weigh the benefits of the MARS FPGA against the cost and the existing ecosystem of the MiSTer.

Hands-On Experience

While detailed hands-on reviews are limited due to the MARS FPGA's pre-release status, initial impressions suggest that the system has the potential to deliver a superior retro gaming experience. Here are some key takeaways from early showcases:

Hardware Showcase: The MARS FPGA has been showcased at events like Free Play Florida, confirming its existence and demonstrating some of its capabilities.
Gameplay and Performance: Early videos and demonstrations show the MARS FPGA running code, although comprehensive gameplay tests are still awaited.

By understanding these specifics, potential buyers can make a more informed decision about whether the MARS FPGA aligns with their needs and expectations in the world of retro gaming.
