Swapping 1.2 with 1.3 Kickstart ROM on A500

kickstart 1.2 is the best kickstart for the A500 and it is the most compatible for games
lot of old games from 1985 to 1988 fails to work on kick 1.3
there is no game that works on kick 1.3 but doesn't works on kick 1.2

I wouldn't say a lot.  But some for sure.  I agree 1.2 is the best for game compatibility and if the OP is not going to ever install a Hard Disk to this A500 he should stick to 1.2  KS 1.3 adds autobooting for HD's.

Hello all,

How hard is it? I just got 4 A500s (one of them in great condition, but with 1.2 and the rest in really bad shape, but working and on Kickstart 1.3)

It's extremely easy.  I would get a $10 IC extractor tool from Radio Shack though.  Using a flat head screwdriver is ok but you can damage the PCB and plastic socket with it if not extra careful.  The IC extractor allows you to pop it out easily with no damage.  But you have to align it just right and pull straight up otherwise you can pull the chip out lop sided and bend some pins, but thats ok as you can straighten then no problem
