ROM Hack Amiitool problems

[Quintex49]

Hi all,
I am new and having problems with Amiitool. I am running Cygwin on Windows 7 and on the command line I typed.....

./amiitool -l -d -k retail.bin -i "30th 8-Bit Link.bin" |xxd and below is what I got.
Could not load keys from "retail.bin": No such file or directory (2)

Could one of you smarter than I people tell me what is wrong? I also tried to run TagMo on an android emulator but sadly it doesn't see my external card reader/writer.

try

-k ./retail.bin

 

[Quintex49]

try

-k ./retail.bin

I tried it but I got the same result. Here is the result:
./amiitool -l -d -k ./retail.bin -i "30th 8-bit Link.bin" | xxd
Could not load keys from "./retail.bin": No such file or directory (2)

Well, I have made it past this hump and am working on the next. See the problem I have now encountered:
$ ./amiitool -e -k retail.bin -i "modified.bin" -o "signed.bin"
Could not open input file: No such file or directory (2)
The preceding decrypt string gave me a dump but when I go to the next step I get the above error. Do I need to create 2 empty .bin files named modified.bin
and signed.bin before the system will find the files? Apparently it doesn't create them.
