it's all a long process of licensing. that's why. oh and they wanna be able to keep count on their sales
theres not all too much trouble in licencing, at least with their own first party software
I've read it somewhere, by releasing old games to new consoles takes same amount of time to make completely new games, even worse since the whole system is different it may took longer since they had to rewrite it from zero, again... this is not on emulation process.
with so much effort to re-release old games to new system they might spend too much money/time for something that less people want.
and while we at it, it also applied to remake edition
bullshit. if anyone knows how to easily emulate their own consoles, its the people that actually built them.
and if some guys on the internet can create emulators that basically give perfect compatibility, you'd expect nintendo to be able to do the same.
once someone gets behind all the encryption of those files, we will probably see that its basically a rom + emulator for every vc download.
i'll give them one thing, gba emulation probably is a little more work than the older consoles, i guess they really have to go and tweak settings there. but as for everything between nes and snes, they could send those out in dozens if they wanted too.
but they dont want that. its bad for the sales.
however, if they remake a game, yes thats different. pokemon heart gold and soul silver probably took about as much money as every other nintendo game to make after its out of its idea stage. however, theres a lot of things falling out again, developement didnt take as long probably, because most of the story, maps and pokemon were already there and didnt need any developement.
similar with black and white 2, there was a lot of work saved by reusing the old region.
so yeah. remakes cost money, but virtual ware, that is pretty much a money printer.
