On the thing about getting cheated by a modder. Back during the PS1 era in 8th Ave mini Chinatown in Brooklyn, NY... modding PS1 was a business for one store. You can get your PS1 modded to play burnt disks for something like $50 or $100. I forget the actual price but you can get your PS1 back by the hour or even half hour. It will work since they will test it out for you. Then... you can browse their collection of burnt games for sale for $20.
Let's say that dude made a nice profit for his skills and connections. Later in '00 or so, he. Swapped to a legit business for legal reasons. Same goes to other video game stores that sold burnt games.
Now, this situation is pretty damn sweet for the buyer and massively sweet for the seller. All the parent had to do for the kid was to front the initial money to get the console and mod and then the kid, like me, could get a game whenever he pleased when he has $20 which was not hard to do for a Chinese kid who get red envelopes on CNY, birthday and Christmas. So I can get games when I wanted in just 10 minutes. Five minute walk to the store beats going to a legit store by using the subway/bus which can take an hour or two one way. Then there was the $50 price tag on the games.
Needless to say, I amassed quite a big burnt game collection. HOWEVER, I did get legit copies of the games at times. Come on, a legit video game store was like a candy shop with all the wonderful colors compared to flipping through a binder.
Now that I think of it, the SNES was similar. Just swap disks with floppies. Not sure on the costs since that was pretty much before I was a buyer. My cousins though had BOXES of floppies of mainstream games from the US and JP, and obscure games as well. So I think each game was pretty damn cheap. Again, whoever did that made massive profit as well.
Now in this day of age with broadband and burners in pretty much everybody houses... everyone can DIY.
... now I want to somehow get my Xbox to play pirated games... JP games. Mainly Metal Wolf Chaos. Thank you internet!
