I noticed that there doesn't appear to be a version of " DRILLER " available with a Trainer.
I know there are cheats on the " Amstrad Action Pokes Disks" for Driller, however I noticed that even with the " Infinite Shields and Energy " cheat enabled, your shield would go down if you bump into one of your drills, you would also die if you went over a mine in " Niccolite ", your energy would also go down if you went into the pool in " Alabaster ".
I think I have now sorted the " Infinite Shield and Energy Cheats ", you no longer lose shield if you bump into a Drill, you can also go over a mine without dying, your energy will also not go down if you go into the pool. ;)
I think the only thing that will kill you is a " Nasty Fall ".
I can't write pokes, but I've made a Trainer by editing the game bin file with edited versions and managed to fit these onto the disk.
I also managed to find how to stop the clock so you should also have a option of " Infinite Time " available now. ;)
Darn, where was this decades ago... :D
