The Playstation wasn't exactly known for arcade perfect ports. and these 3 games ARE NOT arcade perfect by any means but compared to the KOFs and VS games these are some damn fine arcade ports.
Port 1- Capcom VS SNK Pro
Ported from- Dreamcast
Differences- lower resolution, Load times both before and during fights (not long ones however at least...not the way I was playing it) Intro and endings are video files, Voices are sampled at a lower rate, Music restarts between rounds, possible reduction in Character frames.
If only I had known.... I got a Dreamcast JUST to play Capcom VS SNK also it was the only and still is system Street Fighter III and 2nd Impact was on. So naturally......Pro gets ported to the Playstation in the US as by the time we got it the Dreamcast was dead.
By all accounts this is indeed a great port. Obviously the graphics are in a lower resolution and all the other stuff I listed but for the most part the core gameplay is intact. I had issues getting some of Iori and Mai's supers off but I had little issue kicking ass with Cammy as I always do. For what it is it's great and it shows that Capcom really had a mastery of the PS1's Hardware.
It's not the Dreamcast version but if in 2000 all you had was a PS1, you were golden. Might not look as sharp at the Dreamcast but it's still one of the best 2d games on the PS1.
Port 2- Street Fighter Alpha 3
Ported from- CPS2
Differences- Hit polygons instead of Hitboxes, LONG ASS LOAD TIMES (on Playstation hardware it's 30 seconds), possibly THE BEST World Tour mode of the many versions of this game.
It's a bit of a disservice to say I've played Street Fighter Alpha 3.......of the MANY Versions of this game there are only 2 I have not played, The Saturn port, and the PSP port. I KNOW ALPHA 3 Arguably it's the Best Street Fighter there is, and in modern times perhaps second only to Street Fighter IV (which one could argue IS Street Fighter Alpha 4 not truly Street Fighter IV)
So I KNOW ALPHA 3. Back in the day my cousin got this day and date for PS1. I for some reason skipped the 32 bit era but lived vicariously through my cousin some great and not so great games passed through that hardware. But I digress The PS1 Street Fighter Alpha 3 was the only version I had access to as my local arcade sucked. I was amazed save for the load times I probably lost maybe an hour to two hours of my life on load times alone (not an issue now as save states are the best thing ever) But what really makes the PS1 version of Alpha 3 the best......world tour mode. On the Dreamcast (A version so got it got ported TO THE Arcade) world tour had you tackle one region at a time and you could not replay them. On the Playstation you could replay sections you already cleared in World tour. Naturally when I reobtained this version I went right for world tour picked Cammy and started kicking ass. I was in heaven. For all the PS3tards this version is hitting PSN soon I recommend it in the highest.. While you can't argue the Dreamcast version of Alpha 3 is the definitive version of the game it could be argued this is THE BEST Version of the game.
Darkstalkers 3
Ported from- CPS2
Differences- Combines Vampire Savior and Vampire Savior 2, adds a Character Edit mode, It;'s CALLED DARKSTALKERS 3 and NOT Vampire Savior (in Japan it's Vampire Savior EX In US arcades it was released as Vampire Savior as well.)
I'll be honest here, I only spent maybe 5 minutes with this one. For the most part, it's pretty much arcade perfecto load times are quick and don't require graphics in the back ground, Frame loss is minimal. Very good port. so far so good and it has a really neat Character edit that I did not know about either. It's not as good as Vampire Chronicle but it is indeed a very good version which again shows Capcom really knew Playstation Hardware.
