Would it be possible for you to do them again? I remember reading that there is a graphics setting for one of the N64 emulators that rips the textures as they show up. Let me see if I can look it up.
Found it. Searched Google, ended up finding an old topic here (how old? Last post was from June 2008.). Look for "Rice's Video Plugin". Don't remember which N64 emulator I used it on, but it works by turning the plugin on, and rips each sprite into its own image file (just be careful, some assembly may be required). I won't lie and say it will be easy, but your N64 sprites will be clean and crisp without any blur unless the original sprite had a hardcoded blur in its image (as opposed to the N64 being coded to place a blur effect over it)
And if you already honestly used Rice, then I guess we need to end the discussion and make icons for them. And I would need to get a stronger prescription for my glasses...
(If you used a tile viewer to get them, that works too.)
Ton, from what I can tell, unless its a new sheet, they looked a little weird too. But I copied the image into Paint. Did maximum zoom, didn't look like any obvious problems, even took a color and used the MS Paint erase trick.
Well. Your call man.
Edit: The discussion in question.
Here. Don't post there. The topic may be open, but the discussion is closed.
