This morning I worked on Xybort. I added an enemy ship to shoot at. I also added some custom sound effects.

Next, I'm going to work on the enemy ship to move. But I guess this isn't going to be a very thrilling game. It needs something. I'm wondering whether I should add stuff to not shoot at that also moves. Putting the sound effects in was hard because I had to shut off the sounds manually since I put in non-BIOS sounds. This required two sound effect timers: One for the ship shooting and one for the exploding sound. It took a total of a couple of hours.
