Othello in QB64 - Donald Foster - 08-04-2014 12:53 AM

I made some changes to Othello.
1) I changed the board color to a lighter green.
2) I changed the cursor from a small block to a larger yellow outline.
3) I added gray blocks to indicate player's legal moves.

I removed some of the cluttered coded that did not function. When I originally wrote the code on the Tandy 2000, I must had used a key input ASCII code of 18 to display player's legal moves and 127 to remove the blocks that displayed the legal moves. I changed it so it shows the player's legal moves all the time.

You have to realize I going by memory on how the games looked and performed written over 25 years ago on the Tandy 2000. However each game may have some slight changes for the better.
