After stumbling onto an article on Kotaku, i found out that Archive.org has a growing repository of old games for MS-DOS (current count of several thousands). These games are tweaked and fiddled so that they can run through EM-DOSBOX in-browser emulator and can be played (the browser-base emulator is still in beta though) but due to the age bugs may happen. There are all sorts of games from that era (80s-90s), from early sim city games to early battletech and mechwarrior to the original Need for Speed (SE edition). Doom and Doom 2 as well You can find them HERE
One of the best thing about internet tbh. I remember that there is one for flash games as well. Also I still have need for speed 2 SE cd.
If you happen to have the link for the flash one, i'd love it. Yeah, i remember playing quite a few of these games when i was a sproutling in the late 90s
Normally i'd say 'search yourself' but i'm feeling nice so i searched it for you. Here's what's listed as 1-5, presumably english patched maybe, and also a touhou search for software
Found out about it in this video http://bluemaxima.org/flashpoint/downloads/ There seems to be another one too, http://www.flashgamearchive.com/game-directory/
Nice find! It has very high nostalgic value. Even if most of those don't age well. Time is harsh. For game generations, it's even harsher.
Honestly most of the games from that era tend to be better than games these days, because back then a game sold on how fun it was to play rather than visual effects, story, and marketing. There are a lot of fun games there that are better than the new stuff nowadays. My only complaint is that the in-browser emulator isn't a very good way of running them.
If you really look I think even The Library of Congress has or had a site dedicated to all the old games, sadly the link I saved was saved on my old computer but the site I had found had everything from the first Arcade games to the early Dos games that had gone Freeware the last I had been there, but only games that the copyrights had lapsed on at that time (last time I had been there was at least 6 years ago) I think that site had been a playable database site set up between that library and I think it was The Smithsonian Museum or something like that arrangement
