I had a problem with these exact same games, and only these three. Everywhere I looked online suggested they were bad cartridges, but when another copy of Secret Quest didn't work, I thought it must be a problem with my console. I had it (a four switch woodgrain model) plugged directly into the coax in the TV, so I tried plugging the coax into an old DVD player, and then using RCA cables from the DVD player to the TV. After doing this, all four cartridges (two copies of Secret Quest, Astroblast, and Kaboom) worked.
I know this might be a temporary fix to a greater problem with the console itself, but I hope it helps.
