SEGA’s back catalog of games is one of the best there is, and the Japenese giant won’t stand by and watch it die. The new SEGA Forever collection for iOS offers a growing catalog of classic console titles from every era — from Master System to Dreamcast.

What’s more, every one is free to play.

I was never a big fan of the Dreamcast, but it did have a couple of titles I really liked. One of those was Jet Set Radio, a hugely enjoyable game in which you would skate around a city and mark your turf by “tagging” walls, billboards, and rival gang members with spray paint. I’m sure you’ve already heard of it.

Now you can enjoy this awesome game on your iPhone, iPod touch, and iPad — because it’s just hit the App Store.

Earlier this week, Stainless Games brought the 1997 reckless driving sensation that is Carmageddon to iOS, and I haven’t been able to put it down since — it’s as good today as it was 15 years ago on the Dreamcast. However, it does have one issue holding it back: a save game bug that could wipe all your progress.

This week’s must-have apps roundup includes two classic console games that have been reborn on iOS, including Sega’s hugely enjoyable Crazy Taxi, and Acclaim’s 1999 classic Re-Volt — both of which first made their debut on the Dreamcast. It also includes a great little action platformer called Ivy The Kiwi?, a wonderful puzzle game called Girls Like Robots, and more.

Sega has announced that arcade classic Crazy Taxi is coming to iOS devices this month. It hasn’t given us a whole lot of information on the game — none at all, in fact — but it’s expected that the title will be a complete port of the original Dreamcast hit, with the original (and awesome!) Offspring soundtrack.

Acclaim’s 1999 R/C racing classic, Re-Volt, is coming to iOS this month. The title has been ported by development studio Big Bit Ltd, which is run by Nick Baynes, one of the original creators of the game, who has been teasing its release on Twitter.

If you were (or still are) the proud owner of a Sega Dreamcast, then you may remember the classic title Jet Set Radio (Jet Grind Radio in North America). Jet Set Radio was hailed as a revolutionary game due to it being one of the first to make prolific use of a rendering technique called cel-shading (allowing for a “cartoon-like” appearance of 3D rendered objects). While these rendering techniques aren’t so revolutionizing today, Jet Set Radio remains a rollerblading, music loving classic, featuring wholesale amounts of spray paint.
