DS development > Minor differences in GBA SP and DS registers

#37563 - MumblyJoe - Sun Mar 13, 2005 4:48 am

I ran a checksum on the IO registers on the DS and the SP between 0x4000000 and 0x4000FFF and when there was a difference I narrowed it down by chunks and found a couple of differences.

Grab crccheck.gba from there and see what numbers you get on different systems with a flash card. If possible run it in single-rom mode so the loader on your flash card doesn't intefere with the results.

EDIT:

Seems the difference at 0x4000800 was well known as a missing hidden register, but why the timer control data shows up different is something I would like to know.
