Sonic Advance (Android)

Sonic Advance for Android is a port of Sonic Advance to the Android platform. It is a Japanese-only title available as an Android application from the Android Marketplace. Unlike previous releases of Sonic Advance, this version is available as a free download.

The game itself is nearly identical to the Game Boy Advance version. The game image is upscaled 3x from the base image size, which was increased to 264x158 (up from 240x160 from the GBA). Game performance is hit-or-miss depending on the device, with some users reporting 100% speed while others report that it runs ridiculously slow.

Notable Differences
While this port remains faithful to the original Sonic Advance on the GBA, it does contain some differences:

The invincibility theme, originally a remix of the classic featured in Sonic 1 and Sonic 2, is replaced with a remix of the Sonic Advance title theme. The Sonic 1 and Sonic 2 throwback bosses, featured in the X-Zone stage, no longer use the remixes of their original themes. Instead, the two feature the final boss themes from Sonic the Hedgehog 4. There is no known way to access the Sonic and Tails mode within this port. The Android port does not feature the Tiny Chao Garden and contains no files referring to it.

Bugs
Several users have reported bugs within the port ranging from terrible framerate on various Android devices to the game locking up when the device goes into sleep mode. These bugs are most likely caused by the game only being tested on a limited range of hardware.
