With this, all you need is the ZIP archive of any DOS game, and it automatically adds it to your list of games and you're ready to go. No knowledge of DOS commands needed, no making batch files...everything is done for you. It can even install directly from a floppy, if you're lucky enough to still have the originals (and a drive to use them).
How do I play the games?
You can download D-Fend Reloaded HERE. I'm unsure if it works with MacOS, but if it doesn't and you want to play these games, let me know and I'll help you find something that works. There's also instructions and tutorials on D-Fend's site. It's real easy; just install D-Fend, run it, choose the option up top to "Import Archive File", choose the game file you downloaded, and it'll automatically make the game playable. If there's ever any special instructions for the games I post, I'll let you know.
Where do I get games?
First, understand that there are 2 types of old games that I'll link to. First, there's Freeware. This is software that's been released by the original creator to the public for free use and distribution. Second, there's abandonware. These are programs that are no longer supported or available for purchase, but the copyright hasn't necesarily expired. Abandonware sites are generally ignored by any courts and not pursued by the orinigal creators because the distribution of these titles has no financial effect on them and incurs no loss on them.
GOG.com is an outstanding source for non-abandonware older games (and even a few free ones). The games are very cheap and have been modified so they install and run perfectly in Windows. Highly recommended.
Reloaded.org has plenty of Freeware software for free download. Many of these will be in the ZIP format or executable needed for use in D-Fend, others may already be Windows programs so will work from the start with another program.
Abandonia.com offers abandonware games for free download. These are legal to download and play for personal use. Some games listed on the site are there for informational purposes and are not available for download because they are still protected by copyright law and ESA.
There are plenty of other sites out there offering downloads of both freeware and abandonware. I've only found a couple that had games on there that I knew still had active copyrights and shouldn't have been available to download. Still, there are so many games out there.
Feel free to let me know if you have trouble getting it working or finding a particular game.
