The AJAX Remote right now heavily uses JavaScript even for simple links.

Also, from the screenshots it looks like the screen resolution of the 
Nintendo DS is very small, so it would probably require a complete 
overhaul to make the AJAX Remote fit on screen. I'm not sure, whether 
I'll go to that length to support the Nintendo DS as the iPhone 
clearly is the primary addressee for the AJAX Remote.

Nonetheless, to get an idea of what JS Events Opera on the Nintendo 
DS supports and whether swapping graphics and CSS files would 
possibly already be sufficient, please run this test suite on the DS 
(I originally compiled it to get an idea of what the iPhone can and 
can't do):
