Sonic the Hedgehog - Westside Island

Hack of Sonic the Hedgehog


This is a hack of Sonic the Hedgehog for the Sega Genesis. It alters the palette, layout, and names of each level. Bosses are made harder. Level select only allows the choice of the first act of each level. There are few full level layout hacks for this game so it’d be a good idea to give this hack a try.

The patch is in xdelta format. The ROM should be in BIN format.

Great levels , but HARD bosses

Reviewed By: Timaeus on 12 Dec 2015

Without a doubt, the best part of the hack is the new levels and new colours for them, I like that, because there are very few level hacks for Sonic. Of course some levels are hard, that´s why going slower in the first time is a great strategy.

But if you could find a way to keep you lives until the act 3, be sharp, because you’ll game over at least once when you made until the bosses. The bosses here were made harder, and some, hard enough to become frustrating, since you can’t warp to act 3 after game over just because of the level select that always warp you to act 1. The bosses changes were creative of course but nothing that couldn’t deserve a nerf or a level with more lives, at least that (It does have, but not enough for the bosses). SOME bosses here are more save-state than challenging, but not all of then at least.

But even with that, this hack still deserves some attention.
