Happy holidays, everyone!
I've put the Space Patrol Full Edition ROM up at http://spacepatrol.info/
This should play in emulators or on the real system. This edition is nearly identical to the cartridge release. The only minor change is a tweak to the sound effect code, to (hopefully) fix an issue I noticed with the INTV System III and certain sound effects.
This is long overdue.
(And remember to enable ECS for best sound when playing in an emulator!)
