Sonic Advance (Android)
From Sonic Retro
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.
While this port remains faithful to the original Sonic Advance on the GBA, it does contain some differences:
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. While these bugs could simply be the result of the game not being played on the proper hardware, it should be noted that the game was released with a version number of v1.0.0, indicating SEGA may have had plans to release further revisions to fix the issues. However, future revisions were never released.
