Nice to see. Got a post on the portal redirecting to here.
Copied from that as an explanation of some of the terms

Power Save design

Explanation of some of those terms for the unfamiliar or those returning to such things.
FeRAM replaces the need for battery backed memory seen in earlier flash carts. The battery will however need to be there to power the real time clock but as noted is now more easily replaced. Unknown what this means for the save mode employed in the original omega.
Dual working mode presumably means (there was a more extensive Chinese list) a DS mode is available again (touch screen to launch, maybe faster operations and whatnot) where the original Omega and later editions/kernels for the EZ4 dropped such support
GBA-DS link transfer refers to those DS games
that can read the GBA slot (
alternative list and coverage
Rumble was previously seen in their 3 in 1 expansion pack device that became something of a standard. There are a small number of
official DS games with support for the feature and some homebrew as well, it is also possible to hack a ROM to support it but it can be quite involved.
DS Web browser refers to the official web browser which used a GBA slot expansion pack to have some extra RAM (the original DS has a whole 4 megabytes).
RAM expansion pack refers to various pieces of
DS homebrew that support extra RAM to enhance their functionality.
"Power save design" remains to be tested but it was a shortcoming of the Omega where it drew more power than some original carts and flash carts, though it was later improved with software updates.
The 512 movie ROM is the handful of video carts that exceeded the limit seen in all other games.
for a technical explanation. Whether it will be available for homebrew (even back in the GBA era some homebrew went above it, and it could be useful for music and video itself) and ROM hacking purposes remains to be seen but it seems reasonable.
