Unconfirmed reports coming from Japan indicate that the recently released horse training simulation game, Derby Time, allows web browsing similar to that of Wipeout Pure. A number of features have been stated:
* Left Trigger is Back, Right Trigger is Forward, Triangle is Menu, and Square is Reload.
* Single byte Japanese characters still do not work
* On the screen, there is a cell phone antenna icon, a spinning icon that shows loading, and the date.
* Japanese text can be inputted
* The text color and background color default to black
* Though pages will display for an instant, users are soon taken back to the normal page.
At this point, it is not clear how the functionality of the Derby Time browser and the Wipeout Pure browser differ. Well be following this story, so expect an update in the near future. This story comes from PS3/PSP NEWS,(in japanese) who says it was originally posted at 2ch.
