Amiga emulation
« on: March 23, 2012, 08:46:22 AM »
First, you'll need WinUAE. To use it, you'll have to equip it with the kickstart roms (google) (unzip them to their own folder, then go to WinUAE's "Paths" menu and set the "System ROMs" path to that folder). Note: The Kickstarts are illegal, to obtain them legally is cheap enough at: Amiga forever

Then, you'll need to download some games, these are not illegal. Get them from Amiga Emulation Universe Snesorama Game archives or you can download every amiga game in one go HERE EDIT: After looking, this is not an entirely complete list but has most of tghe main games.

Here are some tips:
The "[cr ***]" tag means that the game is a cracked version (each cracking group is represented by three letters - QTX means Quartex, PSG means Prestige, etc.) and has an intro and trainer. If you don't see this tag, it means that the game is exactly as it was on the original disk, to the extent that it can be. (Sometimes, though, there's a nasty bit of copy protection that renders the game unplayable, or at least unwinnable.)

The "(b)" tag means that the game's file is corrupt and will not work. There is never a reason to download a file with this tag; I don't know why they even keep them in the archive.

Make sure that you get ALL disks in a set. They have to be in the SAME set; you can't have disk 1 of a game as cracked by Toxic and disk 2 as cracked by Fairlight. (Well, you MIGHT be able to, but don't assume that your game will work.) Only mix sets if it's absolutely necessary (as with Fightin' Spirit). Once you have a complete set of disks, it helps to extract them to their own folder.

After that, you can configure different parts of the emulator like memory (I set it to use 1 MB of Chip RAM and no Slow or Fast RAM, which works for most games and demos), controls (under "Game Ports", I set Port 1 to use "Keyboard Layout B", as it's the only one that uses the arrow keys - although you're quite welcome to use WASD if you want to), and other settings, like the Amiga model.

Here are the best settings for each model:

Once you've set everything up, go the the "Quickstart" menu and click "Select Disk Image", then browse to a disk image that you've downloaded. After that, click "Start", and the game should load. Press End+Pause to activate WinUAE's high-speed mode if you want the game to load quickly; press the keys again to turn it off. If you're using a cracked image, the game will open up with a crack-intro (also known as a "cracktro") - just click the left mouse button to skip it, or follow the intro's instructions if that doesn't work.

After that, you'll be playing your game!

It's possible, as with many other emulators, to save your state, but that isn't always reliable. Avoid state-saving during loading to minimize the chance of getting a bad save.

If you are unsure of which games are worth trying I suggest looking on Lemon amiga and clicking games at the top. It lists all games by average score and you can filter them by genre to easily find something you will like.

Are you serious?
Here's the Commodore Amiga: http://en.wikipedia.org/wiki/Commodore_Amiga
And on http://www.lemonamiga.com/ the top rated Amiga games are currently:
1. Monkey Island
2. Monkey Island 2
3. Lemmings
4. The Settlers
5. Cannon Fodder
6. Dune 2
7. Sensible World of Soccer
8. XCOM Enemy Unknown
9.  Flashback
10. Syndicate
Further down the list there are games such as Worms, Wings, Sid Meiers Pirates, Civilization, Beneath a Steel Sky etc. Truly Awesome machine, It was 16 bit in 1985 when Nintendo were still on the 8 bit NES.
Quote from: Byte Magazine, August 1994
The Amiga was so far ahead of its time that almost nobody--including Commodore's marketing department--could fully articulate what it was all about. Today, it's obvious the Amiga was the first multimedia computer, but in those days it was derided as a game machine because few people grasped the importance of advanced graphics, sound, and video. Nine years later, vendors are still struggling to make systems that work like 1985 Amigas.
