If games such as Donkey Kong, Donkey Kong Junior, BurgerTime, Frogger, River Raid, and Zaxxon, make you want to relive the good old days you spent with the ColecoVision, then you're in luck. Uberjack has recently released ColEm v2.2.2 which fixes the buffer overflow error affecting units without a battery.

For those unfamiliar with this emulator, it is a port of the ColEm emulator for the Sony PlayStation Portable platform. It's written in C and uses GU (Graphical Utility toolkit) for rendering. If you plan on using this, keep in mind that that system ROM's must reside in the same folder as EBOOT.PBP file. However, game ROM's can be placed anywhere like in the previous version.

If you decide to change the button configuration, remember that changes are not retained after a mapping is modified. If you want to save the changes be sure to press circle after the controls have been configured. If you're using an older build of this, it may not be necessary to upgrade to this version unless you use your PSP with out a battery (i.e. plugged in to a socket)

As with all homebrew, be sure to go over the rather extensive and informative readme document included in the zip file to avoid any problems.
