That would be in front of bg layers (but behind layer 3 if it’s set as super-priority in front of everything). It is 15 colors + transparency for each palette. Sprites use the second half of the CGRAM (palette). Whereas, without the extra X bit, $ff would be the far right of the screen, with only 1 pixel wide showing. With that bit set and the regular X set to $ff, that would be like -1. The extra X bit is so you can smoothly move a sprite off the left side of the screen. That’s 2 bits per sprite, and it can be very tedious to manage. There are 32 bytes in the high table for 128 sprites. N 1st or 2nd set of tiles (you can have up to 512 tiles for sprites). X and Y are screen relative, in pixels (for the top left of the sprite). The low table (512 bytes) is divided into 4 bytes per Sprite, with sprite #0 using bytes 0,1,2,3 and sprite, #1 using bytes 4,5,6,7, etc… up to sprite #127. There are 2 tables in the OAM, and you need to write both of them, usually a DMA during v-blank or forced blank. You need to write data to the OAM RAM to get them to show up on screen. The official docs call sprites “objects”. You may prefer to draw your sprites in another tool, and import those images into SPEZ. In SPEZ, I saved the tiles and palette, which we. This time I manually typed the sprite values in main.asm at the Sprites: label. The SPEZ sprite editor I wrote saves these as tables of numbers HOWEVER I didn’t do that this time.

I call it a “metasprite” when it is a collection of multiple sprites to make up 1 character. You could increase the large sprite size to 32×32, but that would end up wasting more VRAM space on blank spaces. You can also layer sprites on top of each other, but with 15 colors to choose from, you shouldn’t have to. Rex is also made of 2 16×16 sprites, with the lower sprite several pixels to the right of the top one. It is common to use more than 1 sprite for a character. You will notice that Mario is made of 2 16×16 sprites. The OAM RAM controls how each sprites appear.

Nearly all characters are made of sprites… Mario, Link, Megaman, etc. Sprites are the graphic objects that can move around the screen.
