Patch: Informative Miss

Did anyone ever get the ASM patch included with this to work? I tried xkas and asar - but to no avail. I get an "invalid opcode or command" on lines 331 and 364 when trying to compile with xkas on a non-headered FF3 v1.1 ROM. The ips patch works just fine, but I need to get the asm version working with the fix by abyssonym.

Edit: I think I got it working using Xkas 0.06.1 that I found here:

I'm testing now, although I'm worried this is not compatible with the vanish/doom patch based on kjinn22's comment.

Edit #2: Confirmed this does indeed conflict with the vanish/doom patch. That's a big deal breaker for me. Any chance someone knows how to fix this conflict? The conflicting addresses are at 22452-22456 (Headered ROM). I've been wanting to use this patch with ASC for over a year now, so it's a real shame!
