If you're talking about the eee notebooks, you're gonna be tight on storage unless you buy an external hard drive. If you're looking for real old school games, then the best I found were made for dos in the 90s. These games are really short (a full retail version game could be as tiny as 5 megs) and aren't too hard to setup. You'll need dos box (a Microsoft dos emulator which allows you to run old software easily on almost any windows platforms, even vista or 7) that can be found on
http://www.dosbox.com/. For the games, I don't know much about old school RPG games but I can give you a site to check out hundreds of good oldschool games,
http://www.dosgames.com/gameindex.php. It looks pretty nice, has a huge list of games, all classed with their game style (ie RPGs, shooters, adventure, kids, w/e the heck you could think of as a class rofl). I like RPG games, but the real oldschool was probably shooters since they were most popular in the 90s with Doom, Quake and Duke Nukem 3D. In my opinion, settings those games are WAY WAY easier than setting any Nintendo game on a computer, because dos games were made for pc architecture, so you don't need to configure all the damn buttons, and are way easier to run on a pc (no memory freeze or anything), it's basically natural. Plus, most of the games made for dos runs right out of the box, meaning that you can run them flawlessly in dosbox and you're good to go. Choose the way you want to play, but if you really want to play Zelda and fake old school crap like that, then you're better buying off a Nintendo nes, 64 or whatever, because these games are not meant to be played on a PC and if you play them on a laptop you might freeze all your stuff while running these because they take alot of memory and graphic resources. Also they're hard to configure, so if you're new to emulators, I strongly advice using dos box just to get used to this stuff. Long to read, but still worth it. Play good =D. Btw peeps, old school means low end graphic games on roms, so differ those from OLD games, for example Doom (1993 iirc) and Diablo II expansion(2001 is a little old rofl) or Half Life (1998)
