Help me with 100% working games!

I apologize for my english, it isn't perfect.

When i owned a real Amiga my main problem were the fact
that i didn't know if game works fine until the end (logically
i'm speaking of cracked version).

Today what is the situation?

I'm using planet emulation site ...... what adf images i must download?

I must try all possible combinations of disk image files?

There's a way to know what is the right sequence of images to download
to "complete" a game (or what is the working one in the case of a
single disk game) or simply i must try play games exactly like i did in the past?

There is a solution to this "problem"? Please help me!

Thanks in advance for any suggestion

just stay away from [b] flagged games: while it is not very accurate the flag means the game is known to be broken. that's the only almost practical advice
