I suggest that you also post your questions on comp.sys.apple2 and/or
comp.sys.apple2.programmer.  They seem to have more readers.

Your English is better than that of many of the English speaking people that
post.

I prefer the 2IMG disk images since they are more flexible than any other
format (that I know of).  2IMG images can be DOS 3.3 or ProDOS.  2IMG images
can be DOS 3.3 ordered, ProDOS ordered or nibbles.  2IMG supports disk
locking and volume numbers on DOS 3.3 disks (something .dsk images do not).
Most important, 2IMG can be any size up to 32 megabytes so a 2IMG image can
be a 5.25 in. floppy, a 3.5 in floppy or a harddrive partition.  The 2IMG
format can be found at:

I believe that of the Apple IIes only the early (unenhanced) ones had the
6502 processor (my IIe has a 65SC02).  I would think that any Apple IIe
emulator would have to support all the 65SC02 opcodes.

I for one think that, asking questions and giving answers, are what these
newsgroups are all about (or should be).
