i was following a youtube tutorial on how to inject a rom into a .wad to be playable on the wii, and it was going well until i got to the save injection part. the video used a NES rom where you have to choose a source .tpl and a file to inject in VC Save Icon and Save Injector. unfortunately, i am using an N64 rom and the options are source .tpl(s) and folder to inject. what do i need to do at this point? also, instead of doing every step myself (converting a rom to .wad, working on the banner, icons, saving, etc.) can i just download a pre-injected wad where the work is already done?
