Game patch: Dead or Alive 2 (J) [SLPS-25002) playable with the R5900 recompiler. Does not make other versions playable, there seems to be a separate issue with them.

A proper fix for this is not happening nor is it even desirable because of the performance impact it would have, the game seems to unintentionally rely on the RPC arguments remaining in cache until sceSifCallRpc.  A slightly better patch is possible, this one eats some extra EE cycles and might theoretically make the game emulate at less than full speed (but probably won't in practice).
