The SmashPack! has been updated with the newest version of SmashGpsp!

Here is what mATkEUpON had to say:

Here is the third beta of SmashGpsp, a N64 Super Smash Brothers "port", released for Gp32 as SmashGp, and ported to the PSP.

In this version, music has been added, transparency effect on the background layer, with the correspoding settings working. Multiple character pages has been fixed, navigation on character and arena selection menus has been improved. Some sounds have been fixed, and survival mode now preloads some characters to avoid fights with copies of your character only. 24bit bmps are now really supported as background pics (see the 2 new arenas included in the package).
