The first time launching an emunand with neek, I would avoid using forwarders. Instead, manually make sure the bootmiineek folder is renamed to bootmii, and launch "bootmii" (really neek) from the hbc (or priiloader, or bootmii boot2, etc). The onscreen directions after using modmii to build neek or an emunand describes how to even load uneek without an SD card or bootmii folder (using usbloader gx's features menu). [p.s. Check your sd card first without making any changes, if u see a bootmiineek folder and not bootmii, then the forwarder/app was unsuccessful in its attempt to rename the folder before reloading bootmii ios, meaning the current issue is definitely the way you are loading neek)
First boot of a fresh emunand may take up to 15 min or so, usually there is one long blackscreen, then users are prompted to enter some info like console ID name, etc, then another long blackscreen before the emulated system menu loads. If 10 minutes passes and you haven't gotten past the first blackscreen something probably isn't going right.
Anyway, once you've managed to launch neek, subsequent attempts will be very quick, so u can try loading using forwarders and you'll know almost immediately whether it works or not.
Or others
