I advise you not to use timv.bat; many of the MsDOS tools
in psx\bin behave oddly, some only work at 9600 bpd baud rate, etc.

For TIM files, look at timview, timview2, 2d1 and 2d2,
all should be in the scee samples section.

Note that no polygon/sprite can have a texture larger than 256x256;
for any larger picture, use LoadImage or MoveImage to 
Directly copy/load the TIM into the two buffer areas.
This is less than ideal, but there are a number of ways
to do this quickly; demos on this will be forthcoming.
