Y2 Rockbox Beta v0.1.0 for the Innioasis Y2. - Credit to @SPYCEMAGIC for getting Rockbox-Y1 going on top of the Y2 stock firmware. Excellent work.
This beta uses the physically tested V88 firmware base. The release filename is new, but the firmware ZIP is byte-for-byte identical to the tested V88 package.
Important
Flashing uses InnioasisUpdater in full format-download mode and erases the complete player. Back up internal storage, microSD content, settings, playlists, and the complete .rockbox folder before flashing. You can get the original firmware in Innioasis Updater and reinstall it if something goes wrong. (Currently on Windows and Linux / SP Flash Tool methods only - Y2 support for Mac coming soon)..

Beta limitations
Bluetooth playback is untested.
The both-volume fastboot chord did not open fastboot; do not rely on it.
Date/time changes did not persist during testing; the relationship to stock firmware is unresolved.
SNAZZ3 deliberately uses visible 30-pixel margins. This is theme layout, not display scaling.
The Windows updater executable is unsigned; verify its SHA-256 before running it.
