The following article is a RAM map for Excitebike (NES).
| RAM Address | Function | Details |
| 0x0408/F | timer | (f=low 8=high). counts 0 to 10 each |
| 0x03D4 | coord y | some kind of vert pos, not quite though |
| 0x00b0 | lane | which track you are in, 1-4 (0 means sand etc). luke says "when in the air" :s |
| 0x0490/FF | sprites | track sprites, use for collision stuff |
| 0x03E3 | motor temp. | starts at 08. stables at 17 when holding A. overheats at 32. running over "speedup" actually just resets your temp (kind of misleading...) |
| 0x03AC | heading (?) | 2=down, 1 moves towards the moter a little bit (how much?), 0 doesnt move towards the motor/on the motor/... |
| 0x037C | status | 0:ok, 1:puddle, 2:top/bottom of track (1 and 2 = slowdown) |
| 0x0627/C | score | (low nibbles make up score) |
| 0x08f3 | speed | starting at 0, maxes at 46/47. pressing B gets you there faster (increments by 2, where A adds just one), but 47/49 seems the max speed. seems to be a cap somewhere, poking it higher doesnt give you more speed. |
| 0x0090 | x pos | vertical position (out of context of game) |
| 0x000E | moving | i think this is 1 when your standing still and are ready to go, 0 else |
| 0024 & 0034 | timers | count down at start. 0034 starts at 5 counts down every 11 frames then 0024 starts to count down once per frame, when 0024 is at 2, it means go (why 2?) |
 | This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article? |
