This question has been asked quite a bit. You should read some of the threads and check the search engine before posting a question. Anyway...
MeltyBlood --------- The first installment of MeltyBlood
MeltyBlood ReAct --- An "expansion" of MeltyBlood
FinalTuned --------- An update patch of sorts for ReAct
In order to be able to use the mirrormoon english for ReAct you have to have installed MeltyBlood english (if I remember correctly). When you run the english patch for ReAct installer it will ask you to specify where FinalTuned is.
As for the name of the file you mentioned. I'm not sure, but the FinalTuned update can be download from mirrormoon's ReAct section too.
"I settled for that shriek. Those dull vacant eyes... oiled cabbage stench of her...! [...] You know what? I'm sorry if I'm not gonna do this the way you want me to or the way you might. But I will not make an angel out of someone who wasn't an angel...!" -Chief Tyrol, on his beloved wife.
Have you heard about the saying that goes something like "drunk people and kids tell no lies"? Well, that's just a fallacy.
