Good and Safe Roms/Hacks/Emulators

I really want to play pokemon again, but my old DS and Gameboy have mysteriously vanished, so I'm after pokemon games on the internet. I'd like to ask you guys what are your favorite roms/hacks, and especially emulators, and where can I find them? A few things though: It has to be 100% safe, this is the main thing keeping me from just downloading the first links that come up, I don't want to have to deal with viruses. Ideally, it's accessible to someone who isn't particularly tech savvy. I can probably figure out something with a few moving parts, but to me, people who know their way around a computer are basically wizards. And third, I'd like to have a fast forward button, not mandatory, but dear god I hate walking slower than a third grader with a twisted ankle. The games that I'm really after are mostly the gen 4 games, but I also like 3 and 5. Thanks in advance.

Like Pokemon Ash’s Quest, you will be Ash Ketchum and have to play your adventure like what happen in Pokemon Animes. Pokemon Ash Gray now is completed 90% up to episode 50 and will have another update soon. Although it still is Beta Version, it is worth to try. Thank metapod23 for making this hack.
