Would it be possible to install the friver from 2.7 that allows 8GB mem sticks to be compatible? I know that the 8GB sticks aren't out right now but that would be a useful thing to have for the future (I could fit my whole UMD collection onto that and only have 1 UMD in the drive and quite a few SNES and Neo Geo CD roms to).

the 8GB memory sticks will use the same drivers as the <2GB ones.

They are the same hardware, only bigger!

No the drivers for the mem sticks on 2.7 have been changed to allow 8GB mem sticks to be used. No firmware below 2.7 can use 8GB mem sticks, I was asking if the drivers that allow 2.7 to support 8GB mem sticks could be written onto 1.5's flashh so people on 1.5 can use the 8GB mem sticks.

interesting. I wasn't aware of this.

it is theoretically possible, but it would mean completely changing the firmware to load the drivers on boot.

It is a shot in the dark, to be honest. 70% chance of bricking, is my guess.

Besides, Sandisk are not far behind, their super-fast memory sticks are already announced, and i'm sure a massive capacity memory stick will folow soon.

this means making your own firmware, and that is only possible whit a 1.00, so sorry...
i might be wrong

Yeah but could somebody not make an option in flashmod to back up and then replace the 1.5 driver/s with the 2.70 ones while deleting the back ups?

EDIT: That way a custom firmware wouldn't be needed.

Might be possible. But I doubt it'll work that good since 1.5 and 2.7 are completely different. However, if you find the file that's been changed in flash to allow bigger memsticks it should be possible.

When 2.7 was released some people from ps2dev dumped the firmware found the new drivers and gave the names and what they are used for (to show the new features) so I will look for the name of the file/s and see which one it was.

That would be VERY dangerous. By doing that it might be possible to make your whole mem stick drive not work at all, but i dont see how the chances of bricking could increase from any other flash writing..

If you directly replaced it then yes your PSP would be as good as a brick (what is the use of a psp without a mem stick) but if you backed up the original driver before replacing the original driver then I am sure that (if the file that tells the PSP where the driver for the mem stick is located in this case changing the route to the back up then changing back when finished) then it should work perfectly fine.
