I found this on a Hungarian Auction site: http://jatek.vatera.hu/jatekkonzol_...ion_portable_psp/psp_firmware_1659814637.html It's the 3.73 Firmware update... on a UMD. What? What is this? Where is it from? Should I buy it? I certainly don't mind collecting obscure stuff like this, but is it worth the trouble?
