If you look closely in markets and bazaars you can often come across little niche boutique shops like this: Repair shops for instance that specialize in repairing old school video game consoles. They toil all day replacing aging capacitors, upgrading boards to work with modern TVs and put out clean crisp pixel output, rebuilding broken consoles using harvested parts, replacing batteries of old cartridges, replacing worn cases, and even selling karts with libraries of multiple (pirated) ROMs installed. They don’t make much money, but it sustains their work.
