It is the apocalypse after all.

It needs to be one continuous string, yes, do not leave FF bytes between them (The exception is the Remove Gil command, wherein the FF FF are the arguments of that command). The line breaks are for ease of reading the raw hex block, as they coincide with the commands described above it.

The Remove GIL function removes 65535 gil, but it gets run 100 times because each of the item removal commands only removes one copy of the item. So in truth, you are deleting 6553500 gil, which is admittedly not max gil. I'd say yeah, go ahead and add another one or two copies of that command, just to be sure.

So really, just highlight the whole block of raw hex, copy it, and then do paste write (not paste insert) at the specified address. The HxD paste-write hotkey is CTRL+B.

If your HxD is set up to show sixteen columns at a time (which is its default, with 0-F along the top labeling the columns), it'll end up looking something like this.
