It looks like they just burned something to a disc, so you'd still need something to load that disc like a modchip or an action replay.
At this point, if Codejunkies isn't selling any more action replay discs/SD media launcher kits in the US, your best bet would be to just buy a XenoGC. They're like $15 max, super easy to solder to the drive, and then you could buy whatever that Walmart thing is to load Swiss from or burn your own disc for that.
