Address Length Type Description Submitter
$7E0200 512 bytes Misc. OAM (low) table - handles all sprite tiles that are on screen. Each OAM slot contains 4 bytes of data: [XXXXXXXX YYYYYYYY TTTTTTTT yxppccct]

XXXXXXXX and YYYYYYYY bits are the on-screen coordinates from the top-left corner, TTTTTTTT is the tile number, and yxppccct is the tile properties. Each OAM slot are ordered from high priority (in front of other sprite tiles) to low priority.

Ranges from $7E0200-$7E03FF, therefore there are 128 OAM slots.

Address Length Type Description Submitter
$7E0400 32 bytes Misc. OAM (high) table - handles all sprite tiles that are on screen. Each OAM slot contains 2 bits of data in each byte: [SX][SX][SX][SX] (each bracket represents each oam slot).

S is the tile size, X is the x position 9th bit for handling should the tile be crossing the left edge of the screen.

Ranges from $7E0400-$7E041F

(please remove the other one and the old version already moderated)

I see that you sought to give a more accurate explanation about the OAM addresses but... compare them to the entry that's already hosted. See? You have forgotten to, at least, preserve the current information we have (some of it is relevant, like the value a OAM slot assume when it's free). I suggest you merge the explanation you gave with the info that we already have, and you're all set.
