For the past few weeks there have been some very interesting discussions going on in the spanish MagicX Forums concerning understanding and successful reflashing of the ps2's eeprom in order to change the internal settings for different laser types. Now there is no need to send your console to Sony or Use D1vineos illegal methods and place yourself in a questionable legal state (******* managed it to reflash eeprom on ps2). Dampro has released some documentation and ELF to aid in the situation. Right now the documentation is in spanish. I will have a full translation posted very shortly. You can view Dampros thread at the PS2LensChanger Project Page
Fantastic release This will come in handy for the folks who are having a hard time getting ahold of certain laser types. Aren't the Sanyo lasers hard to come by now?
