This agreement is due to FlashMod being Open Source and Public Domain which could cause people to download a Version of FlashMod that might not be from Orbis PSP Development. So for yours protection I urge you not to download FlashMod if it does not say Orbis PSP Development. As for people that want to release their own version of FlashMod please tell me before releasing any unofficial versions.
I Agree by downloading FlashMod Version 2.0 that I relinquish Orbis PSP Development of any liabilities concerning the software effect on my PSP.</blockquote>
Warning any program that writes to your PSP's flash memory has the potential to damage your PSP. So if in doubt do not use.
