SEEKING A CERTAIN KIND OF SOUND EFFECTS

Back in the day I played a lot of RPG Maker games. A LOT of those RPG Maker games had a LOT of sound effects that seemed to be very brief voice/SFX samples culled from dozens and dozens of animes and Japanese fighting games and whatnot of various degrees of popularity/obscurity with a western audience. If you've played a dozen or more RPG Maker games then you know the kind, I think. Generally these were used for grunts of exertion/non-verbal vocalizations, battle cries and "move call-outs" in combat, magical incantations and chants, and whathaveyou.

Now I will admit in the past I have certainly not really been a huge fan of using these kinds of sound effects in games but that's neither here nor there at the moment.

Basically I've just become really curious where people find these sfx or found them back in the day. None of the obvious googley moogley I could think of googling worked at all. Perhaps someone who is of a more, shall we say Japanophile persuasion, or at least who was back in the day, could help me out. Where on the internet did these things come from? I have a feeling there's a conveniently gigantic collection or two kicking around somewhere.
