Converting a cps2 game version to another!

[Gambit20]

Ok this is just an idea so Sorry D if this is supposed to be in support or request cause I had no clue other than the nature of the game itself.

With Street Fighter Zero,I was able to change the language therefore the various settings it in the game to be in english by tweaking a Rom file turning it into sfalpha.(or as D would say "a dump")

Now I know that Vampire Hunter isnt emulated yet even though its older than Vampire savior (all cps2 for those who arent aware)

But what if Someone tryed to change one of the Dump files?Would it change the game?
These questions came to me very easy,I was playing my psx version of darkstalkers 3 and it has the options to change from "A" Darkstalkers "B"Vampire Hunter or "C"Vampire savior.

So........(i'm expecting mink and D here to give their usual reply :D )

Any Idea what file this could be if it is that easy?

if this were at all possible then trust me it would have been done and available the second the vampire saviour romset came out
im not an expert like D but i would have to say no this is not possible since you need the graphic roms and sound roms which cannot be created simply be renaming existing roms
D plz confirm what im saying is right

Hey now I'm not an expert either guys :)
From what I've heard Street Fighter Zero/Alpha is one of the only games that works on, or if it does work on others, nobody has figured out how to do so yet.
Dave (of final burn) I think accidentally discovered it with SFZ...
Also, it only applies to changing the region code, because Street Fighter Zero and SF Alpha are the same game, Zero is just Japanese and Alpha is US.
This is why you can change the region code in many games; because the ROMs often include the data for several regions even though they were released in Japan (I don't know a whole lot about this).

Hmm interesting,
But the fact of the matter is,Once the game changed from Zero to Alpha,Alot of stuff changed.
Like the Haggar code,didnt work anymore since the code whas for the Jap version in my opinion.And the Akuma code was reversed.These are probably just small cookies to what vampire savior has to offer.

Ah.
