Hello Everyone!!!

I'm A.J. Foucault and I've been in the Emulation word since 2001, and in the videogames word since 1994 (when I got my first NES).

Anyway, I don't think you care about that xD, so let me go straight to the point of this post.

I've been having a trouble for ages, and I hope you'll be able to help me =P.

The thing is that everytime I apply an ips patch to a SNES game (by zipping it with the rom, or by using LunarIPS) it says that the thing is corrupt and it doesn't open. I think it is a virus in my computer or something like that.

However, IF I use a pre-patched rom from the internet, it works just fine :S
And as a matter of fact, I have a CD with my first set of roms and in one of them I have Bahamut Lagoon zipped with the patch (I did that in an old computer that I had) and it works just fine.

So, any advice?
Thank You Very Much for you useful help and information!!!

P.S. By the way, right now my OS is Windows Vista, but that's unimportant, because even with my old computer which had XP I had the same problem...

Are you sure that your ROM is in the correct format, including existence of a header if necessary? Most readme files will specify this information. I don't see how it could possibly be a virus, unless someone specifically wrote a virus to corrupt your translated ROMs and only installed it on your system. I hard patch exclusively, and the only problems I ever have are when the ROM isn't in the correct format.

Did you try adding / removing the header? (e.g. with NSRT) Your post wasn't clear about that.

Note that this is not the same as de-/interleaving. You should always keep your ROMs deinterleaved (see NSRT dor that as well).
