We all know ST is an extremely weird game concerning the differences in regions. Chris Doyle and I were discussing some topics about ST yesterday, and the topic about phoenixed boards came up. My theory about them is that each and every single CPS2 game that capcom has made has all the regions saved on the roms. The reason I believe this is that when you boot up US ST you see the SSFIIX logo where the date code is.
So the question of regional differences came up. Chris believed that the only thing saved on the eeporms for the phoenix set is the language differences. I believed that the differences are saved on their as well. So I began the test since I have a spare phoenixed board. The easiest test for this would be zangiefs neutral jump headbutt. So I proceeded to boot the game in US mode and began doing the head butt (took me a long time since the damn ai is retarded lol). So finally I hit chun with it and no dizzy. So I proceeded to boot the game up in JP mode. As soon as ryu jumped at me I hit him with the head butt instant dizzy. I was shocked since I haven’t seen any documentation on this.
My question now is if anyone has any expertise in doing speed tests please do it so that we can make this theory into fact.
