the story behind SSVS is big. to make it short:
after releasing SSV, SNK Playmore annouced SSVS, and said it will have Fatalities and new characters.
SNKP released the MVS version. everyone was happy, except for some Japanese players who complained about the game for being too gory.
when they released the home cart, customers found out that the fatalities were removed.
outraged customers expressed their ingratidute to what happen, especially that SNKP remained silent about the fatalities, and didn't annouce that they were removed from the home version. not to mention the sound glitches and bugs.
SNKP playmore annouced that they will recall the SSVS carts for a fix. they said that the fatalities will be watered down (i.e. no body splitting).
some people sent their carts, and some didn't. the NeoStore also left some "unfixed" carts in stock and sent the rest.
by that time, Razoola had been working on fixing the fatalities and the bugs, and he succeded. now the original full fatalities that were in the MVS can be played at home with the help of his Unibios 2.
SNKP returned the carts, and now we have both versions.

If the above is accurate then, SNK Playmore did released a MVS version ..... can someone please confirm this?
If you are after an AES version, then it appears that, so long as you have a UNI bios version 2.0 or above, get the unfixed version of SSVSp.
