Hi Spencer,
As long as you can get TMODE to work correctly, try using the vibrant drivers
and select the one that says "use tmode" just make sure that you've run TMODE
and TPCLR before you run 3DS – just write the commands into a batchfile that
runs 3DS.
Also, by using TMODE you can change your rendering resolution by using a
different TMODE selection and you won't have to run 3DS VIBCFG each time you
want to change rendering resolution.
hope this helps
