Sonic Triple Trouble (Game Gear) - Complete Playthrough

This is a complete playthrough of Sonic Triple Trouble (also known as Sonic & Tails 2 in Japan) for the Sega Game Gear. All the Chaos Emeralds are collected. This is not a speed run, in fact I try to show most of the levels by exploring them to some extent instead of picking the fastest path all the times.

It also seems that I found a weird bug in Sunset Park 2: getting the Ring on the end of level signpost made me start with 15 rings in the next level (as proven by the total of 20 rings at the end of Sunset Park 3) instead of adding 10 to the current total. I suspect this is happening because the lack of a score tally confused the game. I wonder why 15 and not 10, though.

Enjoy.
