I have heard the PS2 version has issues too. They fucked it up but it is not a surprise because this is SNK USA. I read that they didn't just take the Japanese Orochi Collection and add in '94 and '98, but started from scratch and just did a shit-tastic port job. This is why I do not support them and always buy the Japanese versions, never mind that it takes them WAY WAY WAY WAY WAY too long to brings these out in English, they always fuck them up somehow. I heard the English versions of NGBC and KOF XI are missing progressive scan mode, WTF?
This is why I say if you want that Samurai Shodown collection, go ahead and import the Japanese version (or wait for the PSP version of Tenka). I guarantee you the "English exclusive" SS5 Special will be all kinds of jacked up.
Don't really see the need for this port as the NeoGeo emulator on the system already performs admirably.
It's, you know, for the people who buy stuff LEGITIMATELY. It's just too bad they fucked it up so badly, lolz.
