John,

Yep well now's the time to pull your finger out then isn't my son?

Any help would be of course appreciated as I'm clueless about Miggy development and AGA specific development documentation is very thin on the ground.

Hi mate :) Sorely tempted to help you write that shoot-em-up. Unfortunately last time I did programming on the Amiga was 20 years ago!
