As the topic says I made a patch to convert the psyfer release into the WRG patched release. I have a new site over at 4shared.com which should be somewhat better than my lycos site: http://www.4shared.com/dir/514850/ef8a1bee/sharing.html The site appears as a virtual directory and the file you want is called is called nsmbpatch.zip. What happened is WRG released a patched version of the ROM so it would work on normal flashcarts but when people tried to make an IPS/NINJA patch it got pointlessly large. This xdelta is a few hundred KB and so perfectly fine for distribution. You will need xdelta: http://evanjones.ca/software/xdelta-win32.html In this zip there is a file called WRG.patch, have this file, the unzipped NSMB rom (I have included a rename command so as long as it has a .nds extension name will not matter), and the following batch code made up into a batch file. Run the batch file and it up should come a file called NSMBWRG.nds.gba: this is your patched file. Batch code: Code: rename *.nds NSMB.nds xdelta patch WRG.patch NSMB.nds NSMBWRG.nds.gba Despite my strong aversion to smilies, to WRG and Psyfer. Oh and if I get bored I will see if I can reverse engineer the patch to get the Japanese version working. Oh and I will put the French translation on my new site in a few minutes.
