Since my hack soniNeko (http://info.sonicretro.org/soniNeko) has come to a final release and won't be worked on anymore, I thought it was due to release an official video that plays through the whole game, from the first level to the last one, collecting all the Chaos Emeralds (to get the good ending), and all the Note Monitors.
Please note that this is NOT a speedrun by any mean, I don't aim for the fastest completion, I rather focus on entertainment, though I set a time limit of 0:59 and I turn the Panic Mode on, to make it more challenging and interesting.
With Panic Mode enabled it's impossible to collect rings, shields and invincibilities; this makes the game quite harder, because you get killed the first time you get hit. Also, since you can't collect rings, you need to find an Emerald Monitor to access the special stages.
This video has been split in 4 parts because of that silly 10 minutes limit.

In this part of the video, as a bonus, I'll show also the secret credits screen (C+start at the title screen) and the secret music menu (I won't give away how to get there, though).

Enjoy. (less info)
