The yaroze only has single sided polygons -dup creates 2 polygons facing
in different directions for each of the original ones. Are you sure you
want to
do this as it make your TMD twice the size.

Rsdtool?

The glitches may be because your ordering table is too small.

It could be that your TIM was positioned in the display area of VRAM.

When you use rsdlink it hard codes the data in the TIM into the TMD, so
if you move the TIM the texture disappears. The texture page returned by
rsdlink should have been the same as the TIM.
