Space Invaders - v1

An as accurate to the original arcade game as I can be bothered Space Invaders. Should run at the same speed on turbo boards. Still some occasional issues running on Q68 FPGA boards, but as I don't have one I cannot easily debug.

Space Invaders - the slightly less confident release.

Fixed:

• Wave can now end if player has lost a life
• UFO explosion no longer carries on into the next life
• Invader explosion time shortened so cannot be hit by next bullet.
• Duplicate name removed from help screen
• Improved invader hit detection.
• Invader sound reset after life lost.

This could be the one

All known bugs fixed. But there will me more, there always is!
