You can use anything after 0x80090000, it depends on where your program
goes. Its best to put your data before the main program, as the program
is more likely to change size than the data.

Your files will take up 1x32x32 (0x400), 1x384x64 (0x6000), 1x48x16
(0x300) and 1x64x32 (0x800). If they're TIM files they take up a bit
more, you can check how much by using dir from the dos prompt.

Then it depends on where you put your program 0x80100000 should be fine
in your case.

Your problems are probably due to overwritting files. Try 0x80090000,
0x80091000, 0x80098000 and 0x80099000.
