A silent revolution is taking place in people's living rooms, dorm rooms, and commuter bags all over the world. Gamers are getting their $30-$50 handhelds to flash or use custom firmware, change shells, and make devices that are nothing like the drab plastic they began with. It's retro console modding, an undervalued art form which transforms cheap-to-buy devices into gaming buddies, every one a micro time machine precisely configured to fit the modder's exact level of retro.

If you're like me, looking into the scene was a rabbit hole that you've fallen down in the budget. The R36S, R36 Max, and R36 Ultra are all from the original manufacturer RetroGameConsoles.com, so are the canvas of choice for a new generation of modders. They come at a low enough price to be able to mess up on without any qualms, but they're powerful enough to bring you a lot of fun once you've got them sorted.

Why Bother Modding at All?

Most budget retro handhelds work out of the box, but aren't refined. Stock firmware is typically several months behind, emulator cores are misconfigured, and game libraries frequently include duplicates to hone in on the number of games. It's the first time the modding guide is disappointed: The modding device works, but not quite to the level of singing.

Modding alters that altogether. Using the right custom firmwares (ArkOS, ROCKNIX, EmuELEC), you can get per-game settings for all your games, RetroArch shaders that emulate the true scanlines of a CRT, box art scrapers that will make your library resemble a well-stocked shop, and persistent saves that do actually work. Unscrew the hardware, and there's even more details to be found: replacement thumbstick caps, aftermarket shells in translucent colors, vibration motors connected and tested at handy PCB test points, and heatsinks to keep long sessions cool.

Model Comparison: Which Makes the Best Modding Base?

There are sweet spots for each of the devices. Here is a quick summary that will help you make a decision before making your purchase:

Where to Begin: The Cheap Handheld Modding Starter Path

Custom firmware is the cheapest way to mod a handheld and is the safest. On the R36S, you will start on the community's favorite "canvas" and replace the original ArkOS image with one maintained by the community for your board revision. With utilities such as Balena Etcher, flashing a new SD card is almost a no-brainer these days: flash a new SD card, drop in the proper DTB file for your display panel, and boot up.

With stable custom firmware, a host of retro gaming customization options comes about rapidly. You can theme your EmulationStation frontend, scrape metadata and boxart for thousands of titles, use per-core overlays for Run-Ahead latency reduction (impressively crisp play on GBA), and even enable original Game Boy screen bezels (with per-core RetroArch overlays). You'll be amazed at the first time you visit a nicely organized library with artwork in place.

Going Further: Hardware Mods

Personalized retro consoles are an exciting new area of modding, and hardware mods are the next frontier. The R36S community has captured everything from an M2 heatsink setup (which fits perfectly and is actually a $2 copper square that helps to lower temperatures during long sessions) to the wiring of the vibration motor (which is done with test points on the PCB and does not even require removing the display).

What's ultimately a device that looks and feels like yours is rounded out with translucent aftermarket shells, clicky replacement buttons, custom boot animations, and even internal Wi-Fi dongles. There are step-by-step guides for almost all mods on the RetroHandhelds Discord and r/R36S on Reddit, including pictures and AliExpress part links. Practically any mod you can imagine has a step-by-step guide on the RetroHandhelds Discord, on Reddit's r/R36S, and the R36S Wiki.

The Curation Layer: Making It Personal

All that makes a great modded handheld great is curation. The most effective custom-made retro hand-helds are not necessarily the ones that play the most games, but the ones that play the correct games, provided in the right way by the owner. It could be a well-compacted list of 300 games sorted by era, a front-end with a theme for one particular franchise, or a boot animation to play the Game Boy boot sound whenever you boot the game.

This is where the art of modding consoles starts to kick in. You've built it, you've selected the firmware, you've scraped and organized your art, and you've modified your own hardware; it has something that can't be manufactured in a factory. It turns into a time machine that is specifically geared towards your own gaming past. All of the boots are custom.
