Kazunori Yamauchi was on hand at E3 to talk about not only Gran Turismo coming to PSP, but GT5 as well, and it seems there were a few challenges concerning the PSP version.
Yamauchi said the reason the racer took so long coming to PSP was for a variety of reasons, but mainly the CPU and screen.
“There were a lot of obstacles; the small screen, the lesser CPU power, the lower graphics processing power, and the small amount of memory,” he told Edge in an interview.
“We went through and checked out a lot of the other racing games on PSP, and there’s not a single one that lives up to the Gran Turismo quality.
“We had to work very hard to get it to that level.”
While he admits that there will be no DLC for the PSP version, he is rather excited about Go! and the team is trying to make the download as compact as possible. The goal is to get it within a gigabyte.
In closing, he said that development on Gran Turismo 5 is going well, and may possibly include a crossplatform interface with PSP.
“Development is going well,” he said. “We could put it out at any time, or we could carry on working on it. There’s always something to polish.
“We’re actually thinking about making the PSP garage compatible with the PS3 garage.”
