Tales of Ar'Okés

Do you have a tenkeyless keyboard? Are you not stuck in the 1970s? Then finally, your prayers are answered. This handy script lets you use arrow keys in Tales of Maj'Eyal (and other grid-based numpad-controlled games) and still reliably walk diagonally!

How to use

1. Install AutoHotKey, the scripting language (for Windows only)
2. Click “Download ZIP” at the top right of this page, and extract arrow-keys-to-numpad.ahk to wherever you want it.
3. Whenever you want to use it, simply double-click the script, and it will run in the background!

X-MAS CTF 2020 Writeup: Ken Kutaragi's Secret Code

Or, How to Reverse-Engineer a PS1 Game

X-MAS CTF 2020 was my first CTF – I do ROM hacking, fan translation, and hardware modding, but I haven't done much hacking related to modern systems, so I was a wee bit worried there wouldn't be many challenges suited to my skillset. Imagine my surprise and delight, then, when I saw the challenge Ken Kutaragi's Secret Code, which consists of a PlayStation executable! And wouldn't you know it? I've hacked away at quite a few PS1 games in my day! Not many people solved it, likely because it requires quite niche skills – so let me share those with you!

Identifying our goal

The challenge description is as follows.
