- Pokemini (Pokémon Mini)
- [Freeware] Added 10 free games for PICO-8 and 12 for Pokémon Mini (see below to install them manually from .fwu).
- [GMenu2X] Added an option in “Settings” section that automatically copies default freewares to the SD card.
- [GMenu2X][RetroFE] Alias files are included and preloaded by default for FBA 2012 and MAME 2000.
- [GMenu2X] Set “DrUm3x4” as the default theme instead of “DrUm3x3”.
- [RetroFE] Updated assets for “RetroRoomCovers”, “GameBoy” and “Superlopez” themes for the new systems. Thanks to hyjinx187 for the PICO-8 art, joyrider3774 for the Neo-Geo and MAME arts and xs4all for the Pokémon Mini art.
- [Lib] Added MODPlug, Musepack, FLAC and WavPack support.

Update
- [RetroFE] Disabled subfolder support for faster ROM scanning. If you want to enable it again, just use Commander with READ-WRITE permission (MENU button), open
/usr/games/collections/<SYSTEM>/settings.conf
then changelist.romHierarchy = false
tolist.romHierarchy = true
. - [Libretro] Recompiled all cores from the latest sources.
The Full SD Image is only for people who want to flash a fresh new SD card (all data will be wiped!). Use this file with an image flash tool like Win32 Disk Imager then put the card in your console and it will finalize the process on startup (partition resizing etc).
The Firmware Update should be used to upgrade a previous version of the custom OS but NOT the stock OS. Drop the file at the root of your card then unmount to update.
