Back in December, Hudson somewhat surprisingly released an emulator app for their cult-classic 16-bit console TurboGrafx-16. This emulator, called the TurboGrafx-16 GameBox [Free], features a free-to-download shell that includes the full game of World Sports Competition and houses a hefty selection of other titles that can be unlocked via in-app purchase for $2.99 each. There's also one new rotating tile per day that gives you a chance to play that particular game for 10 minutes, up from the initial 3 minutes offered on the app's release, as a sort of demo to decide if you want to purchase the full version.

We really liked the TurboGrafx-16 GameBox in our review, noting that its virtual controls were about as good as they come on an iOS device that emulates games designed for physical controls and a favorable save system ensured that you could retry tricky sections easily without causing too much frustration.�The initial selection of games available for in-app purchase in the TurboGrafx-16 GameBox featured a range of very good to mediocre titles, with a couple of must-haves like Bonk's Adventure, Ninja Spirit, or R-Type. Today Hudson has released an update for the TurboGrafx-16 GameBox that adds 5 new titles to the in-app catalog which are listed below:

Bonk's Revenge by Hudson Soft

Detana!! TwinBee by Konami

Kaizouchoujin Shubibinman by NCS/extreme

Double Dungeons by NCS/extreme

Benkei Gaiden by Sunsoft

Like a few of the games in the initial release of TurboGrafx-16 GameBox, 3 of the 5 new titles are the PC-Engine versions of the game, the Japanese counterpart to the TurboGrafx-16. As such, their menus, dialogue, and instruction manuals are entirely in Japanese with no option for an English version. For a game like Detana!! TwinBee this isn't as much of an issue, as it's just a vertical shooter and knowing what's going on is secondary to blasting stuff out of the sky. But in the case of Benkei Gaiden, it's a heavily dialogue-driven RPG which will be hard to enjoy if you aren't able to read Japanese text.

Also worth noting is that the full version of Bonk's Revenge is currently free to play as part of a special promotion. Seeing as this will likely be the title that most people are interested in, it's a great chance to actually try it out yourself before committing the cash to unlock the full version. Make sure to update your game to the latest version and give Bonk's Revenge a spin and check out the other 4 new titles in the TurboGrafx-16 GameBox.
