A downloadable game

Ten line BASIC challenges are thing I've had a few goes at, but a classic invaders game seemed a bit too much of a stretch. 

Then a recent competition showed a really nice version for the Acorn Electron. Looking at the source, it took advantage of abbreviations e.g. G. instead of GOTO - unfortunately the Oric does not allow this. 

But I thought I would have a go anyway, and managed to squeeze in the following:

  • Scoring (wow!)
  • Increasing difficulty level (each new wave starts lower down)
  • Sound effects (double wow!)
  • Even some cosmetic effects like an asterisk when an invader is hit.

You might tell that I'm kinda pleased with this one, wasn't sure I could do it.

Install instructions

Install instructions

Best run using an Oric emulator - I use Oricutron.

First download and install Oricutron from here : Oricutron Oric Emulator

Extract the emulator zip file to a location of your choice. 

Once extracted, locate the "tapes" folder then download and save the invaders.tap file to this folder (the .txt file is just the source in text format, not needed to play the game).

Run Oricutron, which will fire up in to Atmos mode by default.

Now type CLOAD"INVADERS.TAP" and press return.  The emulator will load the tape file.

Type LIST to show the program if you wish.  To start type RUN (and press return).
