0x71552 - The very start of the first tiles. Note that graphics are compressed.
0x1B5A - The very start of the graphics decompression (ASM)

Written/Discovered by Lin. Thanks to Coolboyman for ASM help when it was needed.

GRAPHICS DECOMPRESSION
1B5A  ldi a,(hl)				;load a with whatever byte is up for graphics
1B5B  and a					;a AND 1
1B5C  ret z					;if a AND 0xC0 is 0, meaning done compressing, quit
1B5D  bit 7,a					;if the highest bit (x in x*******) is 0
1B5F  jr z,1b73					;jump to 1b73 (Prodedure to set vram data)
1B61  and a,7f					;a AND 0x7F
1B63  ld c,a					;load c with a - bytes to copy?
1B64  ldi a,(hl)				;load a with whatever byte is up for graphics
1B65  push hl					;store where its currently reading from the rom
1B66  ld l,a					;set the lower byte of the reading location to a
1B67  ld h,ff					;set the upper byte to ff
1B69  add hl,de					;add the vram writing location to hl. this should be ffxx, which would mean its setting the vram location to copy from. it will loop around
1B6A  ldi a,(hl)				;load a with whats at hl, aka copy from vram
1B6B  ld (de),a					;set byte in vram location to a
1B6C  inc de					;increase the vram location to write to by 1
1B6D  dec c					;decrease c by 1
1B6E  jr nz,1b6a				;if z is true (c > 0), go back to 1b6a and continue copying
1B70  pop hl					;set the data reading location to what it was before the copy
1B71  jr 1b5a					;repeat the first process
1B73  ld c,a					;load c with a
1B74  ldi a,(hl)				;load a with whatever byte is up for graphics (increases)
1B75  ld (de),a					;set byte in vram location to a, the last read byte
1B76  inc de					;increase the vram location to write to by 1
1B77  dec c					;decrease c by 1
1B78  jr nz,1b74				;if z is true (c > 0), go and finish the current graphics strip
1B7A  jr 1b5a					;repeat the first process
