I had an Amiga A500+.
Mind the big selling point of it at the time was that it had 1MB of RAM. 😁
That’s what I had. The Cartoon Classics pack.

Brilliant!
I see Bart vs the Space Mutants on the box, I have that for the NES. Bloody tough game lol.
There was a cheat for one of the levels, think it was the one that had all the shops. You got to a bit where there was cement and you sunk and died if you landed in it.
I was stuck at that bit for ages until I found the cheat.
That may actually be where I've never got past.. cant remember.
Please tell me the cheat if you remember, lol
I think when you got to the edge of the cement there's a small ledge to jump onto. I think you jumped up and down on it 3 times and it turned into a floating platform that carried you over the cement. Probably about 25 years since I last played it so not 100%.
Also if I remember right you could type cowabunga on the title screen at the start and you got unlimited lives.
Cheers. You are a prince among men.
I'll remember this for next time I play it.
