DOSbox

I'd say emulators would be the way to go which you are using, so if it was me I'd look up tutorials on youtube. I had a problem with age of empires 2 on a windows 8 laptop so I feel your pain. in that case I had the disc, and everything but after installing it the game just wouldn't work:/

I think it sounds possible I am just not great with old PC stuff. I mostly just run back ups of my PS2 games as of now. Now that was a hassle lol. You have to dump the systems bios, and then also rip the game discs yourself. not a ton of fun, but I'd think if you could do that a old PC game sounds simple enough, but I know things rarely areXP

I wish you the best of luck^^

so this is windows 7 deskop but is on 2014 in big c thailand and family buy new computer is windows 7 ultimate

OOO going retro!

I have experience with this.
These are the following methods I use:
A) GOG.com is the first, most legal option for old games, as there's a lot of re-released titles there.
B) Some games can function as low as Windows 3.1 - check what titles you have that are compatible. If so, "Dosbox" can run them. All it takes is a download of that version and installing it inside. Dosbox has the extra advantage of allowing one to freeze the CPU speed or adjust it on command.
C) For win95 titles, that's more tricky. I use Virtual PC 2007 on a dedicated Windows XP machine, as they are less backwards compatible.
E) Finally, in some cases,"ScummVM" can directly emulate some titles. Check their site for their list.

I've played Quake, Blood, Doom and Duke Nukem 3D games with DOSbox and they worked fine!
