I have some trouble with one game: called: Konami Baseball

1st: disk keeps spinning

Then i found with BEGADR, the start, end and execution adress of the game

87e0, c800,87e0

I used the command in the *.bas files

150 DEFUSR=&h44:a=USR(0)
160 BLOAD""BASEBALL.BIN": FORT=1TO4000:NEXTBig smileEFUSR=&h87E0:A=USR(0)

The drive stops, but the game is still crappy: no Konami Logo, and not o.k.

Baseball has a copy protection @adress 010A to 010B, both adresses must be 00 to disable it.

I now how to see the adresses with BEGADR
And i know how to save them with BSAVE"xxxx",&Hxxxx,&hxxxx,&hxxxx

But i dont have any knowledge of "Baseball has a copy protection @adress 010A to 010B, both adresses must be 00 to disable it."

You could use disk view 2 if you insist editing on MSX.
