chrono trigger rom that works please?

for some reason all the roms or chrono trigger on the ds dont work for me.
when i first go in time it gets hung up on the trippy looking screen.
can someone let me know how to fix this?
thanks.

It works fine. Update your firmware if you haven't. If you have, backup and reformat.

thank you so much.
