Sonyc is a 1995 fan game/pirate game for MSX2 computers, developed by Elvis Gallegos and Manuel Pazos, and later ported to the Nintendo Game Boy Advance by the same developers. The latter version is less developed.

While it's commonly referred as an unlicensed game, it's technically a fan game, as it's more focusing on giving homage to the Sonic the Hedgehog series rather than ripping off the series.

MSX2 version

The game's levels are arranged similarly to classic Sonic games: Of the 4 'Zones', each is divided into 3 'Acts'. The first Zone has a grassland theme, as in most Sonic games. The second Zone is a cavern that remains frozen despite the numerous magma rivers flowing through it. The third Zone is an ancient ruins type level filled with sand, stone, and waterfalls. The final Zone takes place in a forest that is similar to Wood Zone, one of the levels cut from Sonic the Hedgehog 2. There are also bonus stages, visited after defeating the guardian of each Zone, which feature letter blocks resembling children's toys and in which Sonic has 60 seconds to collect as many stars as possible.

This version became a freeware in 2003. [1]

Game Boy Advance version

This version's first level was originally believed to be unbeatable. This has been proven to be false. However, due to this, savestates for the emulator Boycott Advance were created to grant players access to other levels. So far, savestates have been created for the ruins and wood levels, courtesy of Stealth. The graphics are glitched when using Visual Boy Advance and mGBA, so it is best to use Boycott Advance. It is also strongly advised to disable the BIOS if one is being used, as the game will not boot otherwise.

An alternative version named "SonyC Demo (PD) [a1].gba" in GoodGBA ROM set fixed the graphic bug and also adds music.
