messing with actual dev_dlash gives more reliable results when it comes to RCO testing.

the flash, while gigantic compared to psp's still has it's restrictions, and there's also size limits of elements like on psp that are being ignored by this.
it's possible to generate files that work on loader and get glitched when written to flash.

it's also good to remember that there are 2 flash sizes, 128 and 256.
assuming that ps3 xmb mods ever reach the levels of psp's, this is bound to cause issues, i haven't done too much testing as of yet and I've already once generated an rco that was simply too massive for the ps3 to handle, the graphics would simply not load, and in addition to that, creating custom add-on's by adding files to rco's and more parameters to xml's the files get very big very fast.

as much as i'd like to use it for testing and save me from bricking a second ps3, i just don't trust it to give accurate results.
The last thing i want to do is create and share a theme and have a hundred people brick a ps3 because it doesn't work correctly :P
