El tio de GameFAQs ha dado nueva info:
1. It did meet my expectations. Im just a little shaken regarding the slow framerate and after-images (ghosting) when a character moves fast. But for me its not a big deal.
2. Everything is in Japanese, only the options are in English.
3. Voices are each characters' native languages. All from T5.
4. Storytelling are still in English.
5. Now that the PSP is widescreen, all black boxes in the cutscenes are gone.
6. I'm used to a ps2 controller, the PSP is kinda hurting my thumb without the bonus D-pad.
7. Tekken Bowling, Tekken Dojo, and Gold Rush are all I've unlocked for now.
8. I haven't tried the Network system yet, I haven't downloaded Ghosts yet.
9. Firmware is 2.60 in case anyone missed it.
Luego lo traduzo por la noche o si no que lo haga otra persona. Pero el tio reitera que pide 2.60.
Un saludo.
