yeah, just tried it and it didn't work. I can see and select the plugins but it just goes back to the "select partition screen". The only thing that I know is wrong, is that I've been using vwii wiiflow 4.2.1 and the guide was for vwii 4.1.1. I can run 4.1.1 but I don't have a forwarder for it and I can't even see the plugins on 4.1. My folders are set out like this for 4.2:
root
---apps
------snes9xGX
------wiiflow
----------bins
----------imgs
----------plugins
---snes9xgx
------roms
------saves
---wiiflow
------boxcovers
------cache
----------banners
----------lists
------codes
----------gct
----------wip
------covers
------custom_banners
------fanart
------help
------languages
------mios
------music
------plugins
------screenshots
------settings
------source_menu
------themes
------trailers
Inside the plugin folder are 4 files
snes.ogg
snes9x-gx config settings
snes9x_next config settings
snes9xgx-mod11.dol
