I don't remember game carts in gold boxes, but I bought my Commodore 128 at Target, when I worked there, around 1990-91. They had all been recently clearanced out, but there was an out-of-box 128 in the chargeback area in the back room, along with a disk drive and a monitor. I asked the store manager if I could buy them at the clearance price, and she said yes. I think I paid something like $30 for the 128 (and the drive), and $50 for the monitor. They had been returned by a customer who said they didn't work, but when I took them home, everything worked just fine.
So, while I don't remember the games you mentioned, I *do* remember Target selling Commodores until at least 1990 (but no later than 1991).
