PSPEText is a text reader for PSP game consoles running custom firmwares. This text reader is implemented as a kernel-space module that gets loaded along side your game. Holding the L and R keys for a few seconds will pause the game and bring up the text reader interface. You can read any ASCII text file on the PSP memory stick.
