if people wanted to just play homebrew, they might as well stick to 1.5
roms and isos make the psp better, why would you carry around 3 or 4 umds when you can just carry a memory stick thats already inside the psp,
umds suck anyways, they break real easy, as soon as the window thing is pushed in, they dont work
psx games on the psp are awesome, im not going to wait for sony to release my favorite psx game and charge my $5-$10 even i already have the game sitting there next to my ps1
aint nothing wrong with isos and roms, its just more convenient to me, plus the iso, psx, and hombrew loading straight from the xmb is a nice touch
