It’s a solid business model: People pirate roms, because they can’t buy them.

If Nintendo would sell their old ass games as roms, we wouldn’t have the problem of them suing emulators into oblivion.

It’s a nice, cheap, easy and legal way of obtaining the ROMs to play on flash carts, emulators and FPGA systems.

Why not? There’s still people born who’ve never played those games and come across them. And besides preserving legacy media is actually a worthwhile cause.
