Who uses ROMS depends on your demographic, in Middle and High school, a TON of my friends used roms. I have a USB stick full of NES, SNES and GB games that I spread around to a lot of people and we played them anytime me had accuses to a PC. I flunked out of Spanish Class and was put into a low level math lab, where we used computers. I, and 3 or so friends in that class, were great at math and would complete the work in the first 15 minutes and played on emulators for the rest of the class. I beat SMB2 in 2 classes. In middle school, all the PCs are connected on a network and we made a folder in the shared folder that anyone can access, and it was filled with roms, also GTA SA, Minecraft and Halo. It eventually got spread around and dumb asses found it and abused it and got games banned.
For the younger generation, ROMs tend to be the way to be the way we find out about retro games, this was how I got into it, after the Nintendo DS and Mario Kart DS sparked my interest.
Roms and VC, ROMS mostly, are keeping prices of carts down, the prices we have now are the result of it. Do you think SMB would be $5 if that was the only way to play SMB? but DKC on VC is not going to bring the price down because there was already a way to play it without the game cart. Xenobale 3D might bring down the Wii version, because there is not other way to play it, Wii Emulation is not as easy as SNES, the players will go for the 3DS $40 version, over the $100 Wii one. Did the Wii U VC version of Metroid Trilogy bring it down? (Actually, Looking at eBay, looks like no)
Maybe, the prices are unaffected in a major way because there are always going to be more people who wants the original VS how many there is. The casual gamer who just want's to play is not going to spend $100 on a game, I refuse to for Earthbound, so are they even a factor? Hmmm . . .
I changed the topic name to reflect the discussion.
