gekkio.fi

What It Is

gekkio.fi is the personal technical homepage of Joonas, a freelance consultant in Finland who currently provides software, firmware, hardware, and gateware consulting through Merulogic Oy. This is not a typical commercial developer-tool website, but rather a professional project index and technical résumé page, highlighting long-term work in areas such as Rust, Game Boy hardware analysis, FPGA/CPLD, digital circuits, and KiCad.

Core Capabilities

From a developer-tool perspective, the most valuable part of the site is its set of public research project links: Game Boy Hardware Database provides data and photos of consoles and cartridges; gb-schematics, gb-research, and Complete Technical Reference focus on Game Boy hardware reverse engineering and technical details; GhidraBoy is a Sharp SM83 / Game Boy extension for Ghidra; and Mooneye GB is a Game Boy research project and emulator written in Rust. In terms of supported languages and ecosystems, the main page explicitly mentions Rust, Bluespec BSV, VHDL, KiCad, and Ghidra.

Pricing and Commercialization

The page does not list consulting rates, product pricing, payment methods, or support SLAs. It provides an email address, public key, GitHub, social accounts, and LinkedIn, making it suitable for contacting the author or browsing the individual project repositories, but the details of commercial collaboration cannot be determined from the page text alone.

Pros and Cons

The main advantage is its strong technical depth, especially for research into retro hardware, CPU reverse engineering, emulators, and Ghidra extensions. The projects are relatively open, and the GitHub entry points are clear. The downside is that it is not a general-purpose developer-tool product and lacks unified installation documentation, API/SDK descriptions, licensing details, and version support information. Actual usability needs to be assessed separately for each project.

Who It’s For

gekkio.fi is suitable for Game Boy/SM83 researchers, reverse engineers, emulator developers, Rust embedded enthusiasts, FPGA/digital circuit learners, and teams looking for relevant consulting experience as a reference. It is not suitable for users looking for an out-of-the-box SaaS product, an enterprise-grade DevTools platform, or standard commercial support.

Access from China

The page does not provide information about access restrictions, so actual connectivity is unknown. Access to external links such as GitHub from mainland China may be affected by the local network environment.
