I asked about 50 questions here, now I'm gonna contribute something. Unfortunately, it's unrelated to Zelda hacking because I have no idea how to code in C# or C++.
This is a game I whipped up entirely in Visual Basic forever ago. It's basically the score of me going through many files in my PC. I can't even read the code I typed. It's pretty bad. The rules: Try to get as close to 21 as you can in each of the 5 piles, but don't go over. You have 3 passes if the randomly-generated number isn't what you want. If you're out of passes and you can't do anything else without going over 21, you must take your score.
Bottom line: if you're bored out of your mind, knock yourself out. Note that it probably won't look too good if you don't have the font "DS DIGITAL" installed in your PC.
