Installation: put hud.prx in seplugins directory on your PSP memory stick and append ms0:/seplugins/hud.prx to vsh.txt and game.txt files.

Usage: default configuration is to show CPU speed, battery percent left and local time in bottom right corner. Press NOTE to access configuration menu. When you exit menu configuration will be automatically saved in ms0:/seplugins/hud.cfg

Known problems: display is best shown in bottom left or right corners, I don't know why it won't work in upper corners just as good as in bottom ones.
