Looks like PSP fans can get their tanks for free on some of the more recent firmwares as Freeplay decided to give us word of his unofficial upgrade for for the Liberty City Stories CheatDevice. This version should allow you to use the cheat device on different firmwares from 2.00 to 3.03.

Here's what he told us:

I hacked version 1.0d of the LCS cheat device so that it uses save slot #9, which makes the exploit work on firmwares 2.71 through 3.03. This should make it possible to run the cheat device on all firmwares from 2.00 through 3.03. I've tested it on 2.00, 2.71, and 3.03, and it works on all of those. For some reason, 2.70 didn't work.

It works just like Edison Carter's original cheat device, so there shouldn't be any troubles with implementing the different cheats, much less installing the device. Still, make sure you check the documentation so you can avoid any problems, alright?
