If your willing to run to the store and buy a gamecube, run to the store and buy a wiimote. Without boot2 bootmii installed you can't do anything without a wiimote. You can't autoboot ssbb-usa, so only swap to ssbb-pal would work and that would be way more work than it is worth.
If you have boot2 bootmii, load the HBC and lunch your gc game from there.
If you don't have boot2 bootmii installed, go buy a wiimote.
If you really don't wan't to buy a wiimote, get a modchip, get some dvd-9 media, some dvd5 media, get ssbb-pal iso, get a swap disc iso with gc controller support, use that to install HBC and priiloader. If your on 4.1 or less you can just burn ssbb-pal.
Just go buy a wiimote, a cheap one if you like.
