Just wanted to give a quick example of how the " TECMO SUPER BOWL" text positioned in 4x4 blocks If we go to 0x05056 in the rom we get the following data: A5 b6. This is a pointer to the data sequence. Flipping it and andding 0x10 for the ines header offset we get 0xB6B5. Since 0x4000 is loaded in as a $A000 bank. B6B5 points to $56B5 At 0x56b5 we have the following sequence 20 76 ; These first two bytes set which 0x0800 size banks from the CHR section of the rom (0x40010 onwards in 28 team) ; we will use that contain the tiles we need 02 ; This byte tells us which bank will be used to draw the 4x4 tile sections 20 ; This byte sets our background pallete index 03, 06 ; These two bytes set (# of metatile rows, # length of the metatile sequence) 09 ; this byte sets the starting location for the metatiles (refer to the image below) 42 43 44 45 46 00 ; these are pointer indexes to draw the metatiles 47 48 49 4A 4B 4C 00 4D 4E 4F 50 AB I made a spreadsheet helper to make things clearer refer to the image below Going through the first line 42= draws part of the white S 43= top part of the S and part of the U 44, draws the red TEC and part of the m as well as part of the top of the U and P. http://puu.sh/m0Sdp/8d2ff758af.png metatile.bmp
