Oh, so you're trying to find the the actual location of the tiles themselves.

Well, if they are being uncompressed, what I have found is that usually what most games will do is decompress into a buffer in RAM and then DMA the tiles over to vram, so usually that buffer data is still there in RAM, so what I would do is dump the ram right at the title screen and view the ram dump in a tile editor, and if you find something (like say tile data @ $8000 for example) I would set a write breakpoint at that location and you should, hopefully, find the decompression routine.
