Yeah the spectrum loading, I went round to a mates house once who had one and we sat there and loaded a game up on it and I was mortified to hear the screeching noise it made :lol: even back then as a 10 year old kid I had enough brains to know it was awful. C64 on the other hand had amazing load music with the SID synthesizer chip which sounded amazing, and memorable tunes that I can still play exactly in my head today from hearing them play hundreds of times, i'll never forget those sounds.
My older brother's legend of a mate came around once and randomly gave me 2 big boxed C64 games to keep, one of them being that Batman game which I loved.
