Re: [cc65] executing program under GSOS on Apple II GS (file type)

If you CATALOG the file you'll see that (afaik) the start address is
zero. The ProDOS "inside" GSOS needs to know the correct start
address. Therefore by default the cc65 linker generates a header with
that information when generating Apple2 programs. This is described
in:
http://www.cc65.org/snapshot-doc/apple2enh-2.html

So if you don't want to use AppleCommander to transfer the program to
a GSOS/ProDOS volume then you'll need to
a) get rid of the cc65 header by using a custom linker configuration file
b) add the correct start address to the BINARY file (or always use
BRUN,A$xxxx to start it)

However I could imagine very well that a SYSTEM file would be a
preferable approach for you:
a) A system file can be started right from the GSOS finder.
b) You don't need to deal with the start address.
c) You don't need to deal with the cc65 header.
You "just" need to change the filetype from BINARY to SYSTEM on your
GSOS/ProDOS volume (afaik there are filetype changers available to do
that).

To create a SYSTEM file instead of a BINARY file with cc65 use the
ld65 option "-C apple2enh-system.cfg":

Use "-t apple2enh" for the Apple IIgs.

If you use cl65 to compile and link in one step then provide both "-t
apple2enh -C apple2enh-system.cfg" for a SYSTEM file:
