If you haven’t heard of Metal Gear, you probably haven’t played video <a href="https://comicvibe.com/5-best-mario-party-games-of-all-time-ranked/” title=”5 Best Mario Party Games Of All Time, Ranked”>games these last few decades. The original Metal Gear dates back to 1987 and launched on the MSX, but the real rise to fame probably started with Metal Gear Solid on the original PlayStation in 1998. What needed a hefty console in 1998 can comfortably fit on a microcontroller in 2026, though, as [David Montero Crespo] demonstrates with his port of MGS to the ESP32-S3.
[David] is — as we always are — standing on the shoulders of giants with this hack. Most specifically, the project relies entirely on the [FoxdieTeam] MGS Reversing decompliation project. Of course what one team decompiles, another can recompile, and in this case [David] chose to recompile the game for Expressif’s exceptional ESP32. It wasn’t quite as easy as just forking the repo and compiling with the ESP32 as a target though, as the blog post explains.
We won’t spoil it, but [David] did have to make some changes to account for the different quirks the MIPS processor in the PlayStation has compared to the Xtensa cores on the microcontroller. Then to make it playable, he put the ESP32-S3 module onto some perfboard with an analog stick from a drone controller, an ILI9341 LCD panel, and a resistor ladder to run the buttons for a barebones handheld.
Fans of MSG and its many sequels may appreciate this replica of the codex communicator. Fans of the ESP32 may remember the Wipeout clone we featured earlier, which already proved the popular microcontroller could handle PlayStation-level graphics. If you were hoping for actual solid metal gears, you can cut your own at home.
