Maybe you are familiar with my Kakariko Village, Forest Temple and Peach's Castle ports to GoldenEye. Now I have ported Blue Resort from Bomberman 64 and Holiday Island from Pilotwings 64.

There are two patches, one console oriented for those of you who want to play on real hardware with a flashcard (although I warn you that these maps are too masive and framerate isn't the best), and another patch emulator oriented with better framerate and longer drawing distances (don't forget to put the right rom settings).
These patches also have my other maps with some minor improvements. And all these maps can be played in Solo Mission mode, but just free roaming (no enemies or objectives).
Here are some making of articles for those who are interested:

There are some comments about polycounts but I didn't remember the numbers exactly, so I'll correct them after I check again.
I hope you enjoy it.
