In order to read Amiga floppies on a PC you would need a Catweasel floppy drive controller unless you convert the floppies to drive images (.ADF) or using a hard-drive installer like WHDLoad on your Amiga first then using a null-modem or ethernet connection to copy the resultant directories to a hard drive image (.HDF). Copy protected software doesn't work under an emulator AFAIK so looking for your games on a website like
Back to the Roots may be your only option.
If you want to run additional games from these websites you may want to get additional Kickstart ROMS by buying the
Amiga Forever CD-ROM package. It also contains special software to let you transfer files between your Amiga and PC easily.
