Re-Translations much?
well that's slittly different.
to complete a project like this thoug would require alot of help.
a hard fact about this is that chrono cross is a little to complicated to be in 16-bit form, but if you merged some plot points together and simplified some aspects of the story than it could be doable.
but some parts of the story would be left out ultimately. for instance: serge turning into lynx would be hard to do, considering you'd spend alot of time as lynx, and he would have to become a pc, but that effect might be hard to pull off because you'd have to remove serge from pc, than after serge is restored to normal all the stats would have to transfer with serge, and lynx could no longer be playable.
all in all this 2d chrono cross could work but alot of rewriting would be in order to make it work on a ct rom.
