Last year, Jake Hunter: Detective Chronicles was translated and released on the DS. However, the translation apparently wasn't of the highest quality, and more than half the game was completely cut. (There were another three cases, plus some bonus material in the original Japanese version.) Following the feedback from the gamers, Aksys will be re-releasing the game under the title "Memories of the Past", which will include the content cut from the Japanese version, with the three cases in "Detective Chronicles", having updated localisation.
There doesn't seem to be an official release date yet; however there does seem to be rumours of a summer release date.
