ZX Spectrum Tom Tom

Just for fun I put a BMP image of the start screen of the +2 in my Tom Tom for one more retro computer fix at work!

Drone Bomber and Surround for the Fignition.

Hi I have just discovered that I did not publish this when I had completed this programme back in February.

I have been playing Julz's mini race game and have made some alterations, the game has sound and is only three blocks!

use left and right to guide the bomb to the bottom of the cavern without touching the sides.

9 run for a slow game.
5 seems a good challenge.

I can complete it in setting 2!

FIGsurround

I have made a surround game based on the Forth Surround Game on the Ace Resource site.

this simple game allows you to move in an area, after you move, a block will randomly appear thus limiting your next move, the more times you move the better your score.
