Masterjun, that's a bit of a stretch if it's deliberate. I don't really care one way or the other, though maybe call it "Speed/Entertainment Tradeoff" since it's for the pun?
Did you see how he enters the name? Correct, he uses the touchscreen.

You know how if you BLJ a lot, you can end up in a weird invisible OOB area where you can run around (on emulator/VC at least, it always seems to crash on console)? Idk if you know why that is, but for those who don't, the function that checks for the floor triangle below Mario converts Mario's position to short integers for the calculations. Since shorts range from -32768 to 32767, if Mario's coordinates are outside of that range they will overflow back into it. This creates an infinite 2D grid of invisible copies of the level, spaced every 65536 units.
The copies (in the ABC chat we were calling them "parallel universes/PUs", idk if that will catch on) have the exact same arrangement of floor and ceiling triangles, but all wall triangles are missing, as are most objects, and all water is gone.

Kurabupengin, could you please start checking if the videos you post are actually good? You are wasting everyone's time, seriously.
The fact that drifting gives you a boost is not a secret, but that guy doesn't even seem to notice that.
Here is a fairly optimized Level 1.

The sprite data for levels starts at $07:C300 (look here).
According to the level data format the sprite data starts with a 1-byte header, then 3 bytes for each sprite and then ends with a 0xFF (which is why you see sizes of 5, 8, 11... bytes).
The first byte of the sprite data is the sprite header.
Each sprite is three bytes long.
|First | |Second| |Last |
YYYYEEsy XXXXSSSS NNNNNNNN
yYYYY = Y position
EE = Extra bits
XXXX = X position
sSSSS = Screen number
NNNNNNNN = Enemy number
(Note: The first byte being FF marks the end of the data)

The forums and IRC channel are frequented by people of all ages, and thus, content posted should consider the possibility of younger readers. While adult-themed conversations are not prohibited, they should be mature, purposed, and limited. In other words, don't be dirty simply to be dirty.

If I am remembering correctly, in the SMW case, death should be counted as negatively as possible (fitness = -MAX_INT) as dying saves no time in the game.

Add a RAM check if a dialog box is open, if so spam the A button and skip the main part of the script.
While you're at it, you might also want to spam the B button for a bit when you didn't move for like 2 seconds.
And also why don't you also press the B button when there is an enemy right in front of you. It will make it more efficient!
See, here are the addresses:
Address Length Type Description
$7E:0094 2 bytes 3 Player X position (16-bit) within the level
$7E:00E4 12 bytes 2 Sprite X position, low byte.
$7E:14E0 12 bytes 2 Sprite X position, high byte.
$7H:L0L0 42 bytes yes Read this address to get the winning value!
But seriously, creaothceann, do you understand the concept of a self-learning AI?
It has to learn to either avoid the message box or get used to it (the message box is a sprite, so it can detect that).

Oops, I'm sorry. For some reason I missed that.

$0643: An Arithmetic Shift Left is done so that the Carry is 1 if B was held, else the Carry is 0.
$0644: This will branch forward if A was not held (since A is now the MSB), but if A was held then we go to:
Because the order of the key is "RLDUTSBA", I suppose that the explanation of $ 0643 and $ 0644 became alternate.
When A=0x80 was pushed, ASL turns on a carry flag.
When B=0x40 was pushed, ASL turns on a negative flag.
Indeed, thank you. I mixed up SNES and NES, because in SNES the first bit is B.
I mapped A of the NES to the same key on my keyboard as B on the SNES, so I thought it was the same. Silly me!
Fixed in the submission text.
