No no no, no ROMs. Download Lunar IPS and make a patch by providing the program with the original ROM and then your new ROM, then you can upload the .ips file generated.http://www.romhacking.net/utilities/240/
Did you try click the "URL Only" part? I think you can upload it there.
The file needs to be compressed to one of the accepted file types. I use 7zip (.7z).
