voilà le tuto extrait de la faq de Brakken (j'ai testé çà marche)

Nintendo 64 - N64 EMU v1/v2
Ceates ISO Image

This emulator is much better then the above one because it has more compatibility and better sound emulation. This emulator is in PAL video mode, so it might not work on some NTSC displays. If you are using GCOS press and hold “Y” button when booting to force NTSC mode. To use this emulator follow these instructions.

(1) Extract the EMU and Paradox GC Tool (located \files\gc-tool12.rar)
(2) Open GC Tool and using it Open the “n64emu.gcm“ image (v1) or exp-n64v2.gcm” image (v2)
(3) V1 – On the right hand side there are two N64 rom images. Simply replace the second one with the rom you wish to use.
(4) V2 - On the right hand side of the screen locate the file "zelda2p.n64" and replace it with another N64 rom image (32MB MAX)
(5) Pick “NO” when it asks to change the file size of the TOC
(6) Close the image and program, rename the .GCM to .ISO and burn (or stream)
