CrossMix-OS is based on TrimUI stock firmware with a more advanced configuration, new emulators and new tools to offer an optimal experience on your TrimUI Smart Pro.

CrossMix-OS is also designed for the community, developers and creators: it supports themes, icon packs, background packs, template for "Best" collections, overlays auto config, …

All components of CrossMix-OS are free and open source.

To make a fresh install:

• Format your SD card in FAT32. (use a genuine, name-brand SD card and not the stock one sold with your console)*
• Download the latest release of CrossMix-OS (in the "assets", at the bottom of the release page, look for "CrossMix-OS_v1.x.x.zip")
• Extract the archive to the root of your formatted SD card.
• Copy your BIOS files into the BIOS folder (on stock SD card copy it from RetroArch/.retroarch/system to BIOS folder)
• Copy your own ROMs into the Roms folder (or copy the Roms folder from stock SD card, rom path changes : PPSSPP -> PSP , OPERA -> PANASONIC , PICO8 -> PICO)
• Insert your SD card into your TrimUI Smart Pro and boot the console.

*Recommended SD card size is at least 128GB for the firmware, emulators, BIOS files and ROMs.

To update, the process is almost the same :

• Run chkdsk/fsck on your SD card first (as there are many bad SD cards, it's always a good idea to check for errors)
• Extract the contents of the new archive on the root of your SD card, overwriting all existing files.

Remark: CrossMix-OS doesn't require any firmware update before installation: it will guide you to update it if required, just let yourself be guided on the first boot.

Remark: CrossMix-OS use the firmware 1.0.4 hotfix 6 by default (no need to update it before your CrossMix installation), hotfix 9 is also supported but boot logo change is disabled.

• Retroarch configuration ovverides: CrossMix OS uses "directory overrides" everywhere. This is the best choice : in many handhelds OS it works with core overrides but this has no sense as some cores are used for multiple platforms. So Directory override is a nice choice but there is an enormous limitation : when you have rom subfolders (for example "GBA/modern games") Retroarch will look for a "modern games" override instead of "GBA" override, fortunately this limitation is managed in CrossMix-OS thanks to FolderOverrideFinder.sh created by Schmurtz.

1. Ensure all players have the same game ROM.
2. Connect all players to the same WLAN (or host-created hotspot).
3. Enable netplay in the "System" menu.
4. Host player enters the game.
5. Other players join the hosted game under "Netplay" after the host begins playing.

I'm Cizia, a passionate retrogamer. I love the TrimUI Smart Pro, but I felt it deserved a more mature OS, better configured, and with more options. I worked tirelessly to create an image that meets my standards, and today, I'm sharing it with you.

There are some features I'm particularly proud of, such as:

• Background and icon selectors: it completes well the native theme selector.
• Overlay selector: Configure your default display ratio and overlay in one click for all platforms, plus new dedicated overlays.
• SwanStation 16/9 mode launcher.
• Extensive work on emulator launchers and configuration.
• Default customization of the OS: custom theme, icons and backgrounds, Polish language added and many new tools.
• Firmware Update Wizard: an automatic guide to help user to update if necessary.
• Best packs standardization: generic launcher, game shortcuts support and images on folders.

I would also like to extend a warm thank you to Kloptops for PortMaster and his tools which are deeply used in CrossMix-OS.

Thanks to Schmurtzm for his numerous scripts, I have revised and integrated them into CrossMix-OS, which have greatly enhanced the available features:

• PSX Analog Detector: Detects PSX games compatible with analog sticks and automatically sets the correct controller configuration.
• BootLogo: An app for easy boot logo flashing on TrimUI Smart Pro.
• EmuCleaner: An app to display only emulators with ROMs installed.
• System Tools: An app to centralize different apps/scripts in one place.
• Resume at Boot: A set of scripts to add a resume game on startup feature.
• Subfolder config override finder is also used in CrossMix-OS.

I hope CrossMix-OS will become a reference among OSes based on the stock OS and continue to improve with community support.
