Okay, but listen good!
Step 1, check out FIX94's Forwarder thread
HERE. Follow all the instructions on the page so u are able to build normal v9 forwarder dols. U will need to install devkit, and download updated libraries and save them to your C drive.
Step 2, modify the v9 forwarder source code. Change whatever the forwarder paths are to wherever u have configurable usb-loader saved (ie. apps\usbloader_cfg\boot.dol). Also do an edit replace, replace "meta" with "meta_gamename", then build the forwarder dol
Step 3, build a crap forwarder channel for
gamename, u already know how to do this so I won't go into details
Step 4, download customize mii from
HERE. Start the program, load the wad that crap made in step 3. Then on the 2nd tab in Customize mii, replace the dol with the dol u created in step 2
Step 5, wherever you have configurable usb-loader saved (ie. apps\usbloader_cfg) create a copy of the "meta.xml" and rename it "meta_gamename.xml". Then u can just include an argument in the xml file to autoboot the title ID of
gamename. U can use the configurator for configurable usb-loader to do this, or if u need help I can copy and paste an example for u when I'm near my Wii hard drive
Step 6, install forwarder wad u made in step 4 and make sure IOS58 is installed on the Wii. Also make sure that
gamename is installed on the external hard drive.
Step 7, launch channel, take out your stopwatch, and realize what a waste of time it was to go through all this just to load the game a couple seconds faster, lol.
good luck
