Installation/Controls Guide

Install Portal: Prelude and the TI-84 emulator with [>these files and links here!<](https://www.speedrun.com/portal_prelude_ti_84/resources/iedar)

The Aperture Science Handheld Portal Device is controlled by number keys 1-9; 8 cardinal directions surround the 5 key, which itself swaps which portal is replaced by your next shot. As such, the game is best controlled with WASD/arrow keys and the numpad.

Rebind your controls in Calculator > Options > Keys, in whatever configuration you like! My preferred keyboard layout is:

UP	=> [W]

LEFT	=> [A]

DOWN	=> [S]

RIGHT	=> [D]

2ND	=> [Numpad Enter] (Pick up box/Select)

CLEAR	=> [Esc] (Pause)

The Calculator will go to sleep 5 minutes past the end of the screen-shake cutscene, producing an invalid room when turned back on, so it is useful to have these keys bound to an easily-accessible row on the keyboard:

Debug	 > Reset Calculator   => [Fn key above Numpad /]

Debug	 > Turn on calculator => [Numpad /]

Emulator > APPS	=> [Numpad *]

Emulator > DOWN	=> [Numpad -]

Emulator > ENTER => [Numpad +]

Emulator > 2ND	=> [Numpad Enter]

**LEAVING THE CALCULATOR OFF when pressing Reset will prevent your mid-run progress from clearing.**

All set up? Enjoy!
