I found upscaled and remastered pngs for project64 mods but can't get them to work. After loading the pngs the emulator freezes. I can't use the same pngs in my pc version though. Game looks really updated with those but the project for N64 and the one by facebook shadowman fan club is different. By searching I found out that the guy who remade the pngs for project64 is living in the same city as me so I texted him and waiting for a reply.
