Tower, so really who is losing money with this Mame stuff? The original designer? The company that owns it's rights now? Or you who spent money on PCB's when you could have gotten the ROMs for cheap/free?
As for this website that sells ROMs, first time I've ever heard it mentioned, I had no idea about it. I'll have to check that out.
As for why alot of the older ROMs should be cheap? You got it right, supply and demand. If someone had the choice to get a ROM illegally for free or spend $20.00+ for it, they'd choose the illegal way. But, much like MP3's, giving people the option to buy individual songs(ROMs) for a good fair price has allowed both parties to be satisfied. Solving consumers who were afraid to download and allowing record company's to make money on their product (which they obviously should). So you need to look at the market, which does include illegal downloading, and comeup with a price which will be low enough for people to slow their downloading craze and high enough for you to make max profits on it. An optimum price.
You can say downloading is illegal till you're blue in the face. I've never said that it's not, I don't think anyone has said that it's not illegal. But instead of making this a right or wrong argument why not discuss ways to make all parties happy such as legal reasonably priced ROM distributors like this one that was mentioned.
Reason? Because if fair priced ROM dealers like that become the main way for ROM distribution, they'll earn money, the owner of the games rights will for selling the rights to that dealer and I'll get a game for fair money which leaves...you paying more money for PCB's and thus your real point with this whole argument..."what about me?!".
