2. Actual Gameplay Hacking Data
******************************************************************************
a)Big Tileset Hack:
b)Misc - Cant be bothered to organize it so here is loads of data...
c)Personal Information! - My notes!!! Might be of help!
a)Big Tileset Hack:
This gives you 127 tiles instead of 48!
Instructions... Just Copy the Hex to their adresses.
How to use bigger tilesets - Remember that the tileset header has two unused bytes? 0000?
Now they are the two byte pointer to the extra tiles! the extra tiles get loaded at 01:8800(VRAM1)
So you can use them by inputing 80-FF in the block data!
Palettes: After the regular tileset pallete declaration start to enter the rest of the tiles! from 60-FF.
Offsets:
00:2944 - Call $DrwVram1, Call 2953
02:4046 - Call $UseVRAM1
02:4091 - Call $UseVRAM1
$DrwVram1 ( I normally put this at 00:0080 )

ld a,(d0c2); Get tileset Bank
call 0AF0 - Load GFX
ld a,(d0ce) ; Check for Extra Tileset!
cp 00 ; If its blank then
jr z,end ; return!
ld hl,d0cd - Get extra tileset pointer
ld a,(hl) ; Load Pointer into HL
inc hl
ld h,(hl)
ld l,a
ld de,9000 ; Put extra Tiles at 9000
ld a,(d0c2); Get tileset Bank
call 0AF0 - Load GFX
$end:
ld a,00 ;Set Vram to 0 again
ld (ff00+4f),a
ret
$UseVRAM1 ( I normaly put this at 00:0070 )
add a,08 - Adds 8 to the pallete declaration so it loads the that tile at VRAM0 0-7 VRAM 1 8-F
