.~: Is there any good graphics plugin for Resident Evil 2 ? :~.

I think you'd be much happier playing the PSX version, but if you really want to try and get the N64 version working, search the board. This has been discussed a few dozen times in the past.

Are there any other plugins that can handle the game's graphics? Glide64 is useless to me. Rice's seems all right, but all of the 3-D graphics overlap the pre-rendered ones and just looks really goofy.

No, not to my knowledge anyway. If there were, people would have posted about it several times already.

Yes there is, at least I was able to watch the whole Leon and Claire Intro and played until the part you get to the police station.
Then I just started playing the PSX version, because the N64 version looks really horrible on the PC.
Look at the Mupen64 forum.
You need to use glide, a glide wrapper (i don't remember which, but it's somewhere in mupen's forum) and mupem.
