I've never owned a 1.3 Amiga & I don't remember any games that didn't work on 1.3, only a version of soundtracker. All the degrader utils that people used on a500+/a600/a1200 were 1.3
yes most of degraders uses kick 1.3
they used kick 1.3 because it was the standart for the A500 after 1988
but there are A500 and A2000 manufactured in 1987 that comes with kick 1.2
and lot of bad written games from that era don't works on kick 1.3 like I said in my previous post
you can softkick kickstart 1.2 using skick346 on aminet
kick 1.2 is the kickstart I use to degrade my A1200 to play A500 games
btw,also there a cup of bad written games that only works on kick 1.1
I don't remember which ones now ....were made for the A1000
