Why hasn't Sega ported it officially?

Licensing & Source Code: The game was co-developed by Dimps. While Dimps still exists, retrieving and polishing the original C code for modern ARM64 processors requires significant investment.

The "Collection" Strategy: Instead of standalone ports, Sega has periodically released compilations. Sonic Advance 2 was included in Sonic Advance + Sonic Pinball Party for the ill-fated N-Gage, and later for the Nintendo Wii U Virtual Console. On modern consoles, it is available via the Nintendo Switch Online + Expansion Pack (GBA library). On Android? Nothing.

Piracy Fears: Historically, Sega’s standalone mobile ports (like Crazy Taxi and Sonic CD) were so easy to pirate that the company may view a Advance 2 port as financially unviable.
