Will this version have voice acting???
Did the PSP version have it??

I assume so, though with the limitation of space on the DS game carts, one might guess that they might be further limited, and possibly only in one language (English, I'd assume)....Though it is POSSIBLE that all the voice work in the PSP version, is present in this version.

It isn't currently known for sure, since the game isn't out, and so far as I know there are no reviews out for it....

And yes, the PSP version has it, as I said in the thread you created on the PSP version's forum...

I've read that the only difference between this one and the PSP one is the DS one has a lower quality picture.

Lower picture quality is a given, pretty much. The DS's screens and the video processor just aren't up there in graphics quality, at least compared to the PSP....

Even if all the voice work is on the DS version as well, I would imagine that the audio quality (much like the picture quality) will be a little lower. Audio takes up a lot of memory, after all....

BTW: I think the DS memory carts are what? 1GB? Or can they possibly be larger?

I realy don't think it will have Voice adeio. they can get 4 Gig I know that.My freind hacked one.

With up to 4GB to work with, they should be more then fine, since the UMD for the PSP is what? About 1.8 or 2GB?

Providing they have at least that much to work with, they'll probably be just fine with the voice work....

quote IGN

All of the original English voice acting will appear in Disgaea DS. The first game on PS2 also included a Japanese language track, but unfortunately space restrictions on the DS will prevent players from experiencing the non-translated voices.
