I have to admire the work of the dedicated folk who make it their business to hack any Dead or Alive games in order to catch a glimpse of polygonal titty.
Latest Dead or Alive game, DOA: Paradise on the PSP has had the treatment. Those of you with custom firmware PSPs (you naughty people) can enjoy the sight of Kasumi and the rest of the girls "au naturelle" as they laze around the pool, jiggling and rubbing together playfully.
If that's the sort of thing that turns you on, why not just go out and buy a couple of hundred tubs of flesh-coloured play-doh and knock up your own DOA girl complete with realistic orifices. It'll probably take the same amount of effort as getting the patch to work.
