Edit: We now have Snootae Bot v1.0.4.1!
Disclaimer:
This bot was not created by me. It was created by... you guessed it, Snootae.
YOU MUST HAVE MAPLESTORY OPEN ALREADY WHEN YOU RUN THIS! IF YOU MAKE THAT MISTAKE I WILL SLAP YOU! 
*Note* All of the keys are now changable, but not all the keys are supported.
Supported Keys:
Letters (a-z)
Insert, Delete, Home, Page Up and Page Down
Shift, Control and Alt
Numbers (0-9) Non-Numpad
Snootae Bot v1.0.4.1 
Log:
1.0.4.1 Added AC and all keys now auto-save to Settings.ini
1.0.3.1 Added changable keys
1.0.2.2 Increased the size of the delay boxes and added settings auto-save
1.0.1.2 Added 3 autoskills and changed hotkeys
1.0.0.2 Got it working with auto attack, loot, jump and pot
Snootae bot uses PMX.dll which sends keys to the maplestory window,
and can be used while maple is minimized. It has Auto Attack, Auto Loot, Auto Jump and Auto Pot functions.
This .rar comes with SnootaeBot.exe, Instruction.txt, PMX.dll and slkscrn.ttf. The dll is required for the bot to work, and the font is used in the program so you wont be able to read anything in the program without it. So don't get rid of it.
Functions:
Stop All - F5 - Stops all function
Auto Attack - F6 - Presses the 'CTRL' key.
Auto Loot - F6 - Presses the 'z' key.
Auto Jump - F7 - Presses the 'ALT' key.
Auto Pot - F9 - Presses the '9' key for Hp Pots, '0' for Mp Pots
Auto Skill 1 - F10 - Presses the 'v' key
Auto Skill 2 - F11 - Presses the 'b' key
Auto Skill 3 - F12 - Presses the 'n' key
You can adjust all of the delays by clicking the 'Open/Close Settings' button,
the delays are all changable and they are in milliseconds (1/1000 of a second)
Problems that may occur:
Problem: Auto Pot started and only mp or hp pots being used.
Answer: When using it on my computer i have found the delays for mp and hp must be at least 1000 ms apart, or one of the two will not work. We haven't found a way to fix it yet.
Problem: Can't read text in program,
Answer: Copy slkscrn.ttf to CWindows\Fonts to install the font that is used.
Problem: Bot having error and needing to close.
Answer 1: No PMX.dll found, this is required and comes with the bot.
Answer 2: A non-numerical (e.g. 'a', 'b', 'c', '*') character entered into one of the delay boxes.
Answer 3: No MapleStory Window found,
you can't start the bot until MapleStory is open. Open it!
