FODA, are you not going to make a custom track where you break the speed of light?

i already have a run on such a track, but i just lay the H ramps ramdomly, it gets an insane speed but thats pretty much everything that happens on it. http://www.angelfire.com/ex/uobt/excitebike-ju-demonstration-foda.zip right-click, save target as... Edit by Bisqwit: fixed link

Insane = Understatement That must've been like 500 miles an hour, the nametable was being updated too fast for the game o_o (or rather, the window wasn't moving fast enough to keep up with the nametable updates, so parts of the track appeared before they actually showed up -- consider making a run of ntohing but H ramps next time ;))

Hi all--I've started working on a new version of the Excitebike TAS. I've figured out the programming, and in the process, discovered some nice tricks. Here's track 0 http://lukeg.50webs.com/ExcitebikeWIP-Luke.fcm I finish in 37.50, which is 1.42 ahead of the current movie. My interesting discovery is that input affecting your speed is only checked every 4 frames. First, that means that you only have to tap B every 4 frames, which will prevent the engine from overheating. Further, after going over a jump, you only have to press forward once every 4 frames to preserve your speed. While in the air, there is also a 4-frame timer for checking how your input affects the slant of the bike. If this timer is not in synch with the speed timer, you can actually tilt your bike backwards in the air while not losing speed!

Impressive discoveries. You just learned how to fly, or almost :) I'm looking forward to a whole run now.

Very nice! Now you only need to make sure that the current route for each track is correct.

Whoops, the 2-player input is just because my configuration is a bit messed up (probably from doing arkanoid actually). But it doesn't hurt anything so I won't redo it... Anyway here's a new WIP http://lukeg.50webs.com/ExcitebikeWIP-Luke-2.fcm this does tracks 0,1,2. I'm redoing track 2 because I found a way to get a bit more speed. Now that I know the tricks, I'm progressing pretty fast. I should have it done in a day or two I think.

I'm not making this movie. I give up on actually trying to TAS anything; matching JXQ's skill in playing is a lost cause. Anyway, short and to the point (more details if this thread has interest): the optimal speed is 0x0800 (although 0x081F is optimal for shorter periods of time). This means that the former idea of "more speed = faster game" is incorrect, as shocking as it is. Anybody up for working on an improvement? I can provide you with Lua scripts for FCEUX that detail anything you might need to know.

So would you say that in some cases, 0x081F is optimaler? :)

No, more a case that one is optimal except when the other is. (0x81F will quickly become inoptimal if it takes too long)

I added it up. 
C#    JXQ     81F
0    36.54   36.30
1    38.24   38.00
2    38.86   -----  (never goes above 800)
3    41.98   -----
4    41.02   41.02  (not high enough long enough for it to matter)
5    31.74   31.29
            
              0.93  max improvement (actual will probably be lower)
"81F" is just from forcing RAM to 81F if it's above that. You'd have to decelerate otherwise, but considering the fact you have about 16 frames to do so and you drop speed rather fast, it probably won't be much of a problem (losses from these times probably won't be very high). 0.93sec isn't a whole lot though, unfortunately.

I've had my eye on improving this game for several months, and when I saw this post I figured if I could find even 1 improvement myself to go along w/ xkeeper's, I'd do a run. Happily, I have done so...as JXQ suspected, there is indeed a way to take (at least) 1 jump with less slowdown. xkeeper: I don't know how you figured out the "delay to advance" thing, but...whoa. Nicely done!

As many times as I seen runs + improvements of this game, it appears I've seen enough to witness the creation of a weapon that will set the world record forever. From here on, it could take 1000 years to improve again.
