I have just bought an A1200 . already had a A500

When the 1200 is in 1.3 Kick mode, I only have one game disk that runs correctly

It's an Emerald Mine disk that states "runs in any Amiga"

Would this be because the bootblock is a universal one, or will it be more extensive changes to the game???

If its the bootblock, can I simply copy it to other games?

Can I get more universal bootblocks on the web?

Or am I on the wrong track
