If the original disks were in amiga dos format then yes. Either by loading them in UAE or by ADFexplorer and treat them as regular disk
However, most game disks are not in Amiga dos format (df0:ndos icon on the workbench) so unless you have an editor for the game or are very good with a hexeditor I'd say, no you can't edit the teams
Welcome aboard amiga.org by the way...
