CrossMix OS for Trimui Smart Pro S -upgrade card

CrossMix, the enhanced OS for TrimUI Smart Pro S

If you have a Trimui Smart Pro S or are considering buying one, then this card upgrade will be the icing on the cake.

Your TrimUI Smart Pro S is already a capable little machine. CrossMix-OS just unlocks what it was always capable of.

Built on CrossMix-OS v1.2.1, this pre-loaded SD card skips the setup entirely — no installation, no scraping, no config files to wrestle with. Boot up, and you’re already in.

A game library worth keeping

Over 15,000 games, hand-picked across 55 systems. No shovelware, no duplicates — just the titles that actually hold up. The main menu surfaces the best-known classics alongside modern homebrews and hidden gems, while dedicated subfolders keep rom hacks, Japanese-to-English translations, and new homebrew releases neatly out of the way until you want them.

The original TrimUI romset is included too, cleaned up and re-scraped with proper box art.

CrossMix OS, Emulation that just works

100+ emulators, pre-tuned. DOS titles boot with controls already mapped. Game Boy, Game Boy Colour, and Neo Geo Pocket each get platform-specific tweaks for accuracy. Every system has its own overlay, and the full Vectrex library runs with game-specific overlays throughout. Auto-save on exit, auto-resume on launch.

More than a game machine

System Tools gives you 11 icon sets and 7 background collections to work through, and RGB settings are all adjustable. Moonlight streaming lets you pull PC games onto the handheld. FTP, SSH, HTTP, and a file manager are built in for when you want to dig deeper.
Everything you need is pre-installed. First boot takes a few minutes to optimise — after that, it’s just playing.

What’s in the box

1 x Brand-name 128GB quality SD card
1 x Custom Firmware operating system with 40+ configured consoles titles

The boring stuff

– While the Custom Firmware has been tested. Due to the nature of emulation, titles that may come with an SD card are as is, and no guarantees are provided.
– The game console in the picture is for reference only and not included
