CrossMix-OS

CrossMix-OS is a custom firmware for the TrimUI Smart Pro handheld, built on top of the TrimUI stock user interface with refined configurations, additional emulators, and additional apps.

CrossMix-OS uses its own directory scheme case-sensitive names.

BIOS

Because CrossMix-OS uses RetroArch under the hood, the instructions are generally the same as RetroArch. By default, the CrossMix-OS BIOS directory is /BIOS/:

igir copy extract test clean ^
  --dat "https://raw.githubusercontent.com/libretro/libretro-database/master/dat/System.dat" ^

  --output E:\BIOS

Replace the /Volumes/CROSSMIX drive name with whatever your SD card is named:

igir copy extract test clean \
  --dat "https://raw.githubusercontent.com/libretro/libretro-database/master/dat/System.dat" \
  --input BIOS \
  --output /Volumes/CROSSMIX/BIOS

Replace the /media/CROSSMIX path with wherever your SD card is mounted:

  --dat "https://raw.githubusercontent.com/libretro/libretro-database/master/dat/System.dat" \
