Chrono Trigger is getting a re-release on the Nintendo DS. As far as the screenshots i have seen it is a direct port no graphical or sound upgrades. Supposedly there is a new Dungeon bonus level, Not sure what they are going to use the stylus for. Plus i would not be suprised if the game got a beastiary like the final fantasy games.
Now then real question is will it be a new japanese to english translation more faithful than the original release, or have the slowdown problem Prevalent in the US PS1 port uprade unlike the Japan release.
The US release of final fantasy VI (aka III on the snes) on the PS1 also had bad slowdown. 2 good reasons to own a snes, A third would be because it had secret of mana which has never been re-released.
The third part in the Chrono Trilogy will probably now never be made since Sakaguchi left SquareEnix. He has said Blue Dragon is what he wanted Crono Trigger 3 to be. That game is not even as good as Chrono Cross which sucks unlike the first installment, Trigger which was awesome mix of both sci fi and fantasy.
