there seems to be something unique about the V9 consoles, as special V9 patches for HDL were also needed.
But i did find during my tests that the ule/ps2browser method will re-trigger an exploit if the game is listed in the title.db on all those consoles i tested.
Well, atleast now we have a way of booting any kind of application whether it be PSX backup or PS2 homebrew, as long as you have a pressed PSX disc.. I'm sure everyone can manage to get their hands on one...
And as for ppl who have no way of setting up their MC for the exploit, they could boot time swap with a disassembled PS2 just ONCE to boot the MC exploit setup disc, or ULE, so that they can install it.
I'm not sure if this is of any use to anyone, but I've observed some interesting behavior on booting ps1 backups. I use the gameshark psx code archive cd as my swap disc. The first time trying to boot a game with a larger TOC than the gameshark disc will fail (which is supposed to happen, I guess). It spins the swapped disc during the first try, then immediately pushing X again (about 2 or 3 seconds after pushing X the first time) will boot it, instantly, without reading the disc again. This probably isn't much good as it's already running the PS1DRV module already when using the gameshark.
My theory is that the drive's firmware is failing some integrity check on the first try when it reads the disc. Because it still assumes the disc is original because of the swap, information from the boot disc is replaced with information read from the swapped disc or it bypasses the check altogether for backward compatability's sake, then when I push X again, it works.
Unfortunately, this trick of booting backup PSX games does not work with V7 PS2s.
