I fixed the joystick for CPC - that was an oversight on my part. I've changed the background to grey - I originally avoided it since grey is quite dark on the CPC.
I'll have to look into what changes need to be made to work on GX4000.
And your game is already compatible on GX4000. You even mapped the retry key on button 2. Wonderful! But imo, a confirmation would be nice to avoid any mistake while playing
PS : on level 43, the "," is missing to correctly write "Long, Long, Long
