I finally had some spare time to go through and make this, my A1200 is in serious need of repairs but a friend from the internet lent me his A1200 so I could clean it up and get it configured really nicely for him, so I've had the chance to test it thoroughly. I've included three separate drawers for DOOM, DOOM2 and UltimateDOOM, and they all have a copy of the game files, so the archive is quite large from the redundancy, but this is just the easiest way to have the game set up on your Amiga. Just extract the AmigaDOOM.lha file into your games drawer, then all you need to do is copy Doom.wad, Doom2.wad and DoomU.wad into their corresponding drawers. Then all you have to do is double click on the icon for each game to launch it.
I have configured the game to use the later, better sounding MIDI library plugin, and copied over the set of better, optimised instruments, CD32 controls and buffered sound effects enabled. You can use the mouse and keyboard as well, if you don't have a CD32 or USB control pad. You can increase the screen size by pressing + and - on the keyboard, and change the detail with F5. If you're not happy with the screen mode it runs in, or you want to disable the music (the music slows the game down a little bit) you can configure the settings by showing all the files in the drawer and executing DoomAttackPrefs. You can also run the game from AmigaDOS, which might be smoother. Let's just pretend you have extracted your AmigaDOOM.lha to Work:Games/FPS/ When you have rebooted without a Startup-Sequence (by holding down the two mouse buttons before booting/rebooting), this is what you need to type:
Assign Env: RAM:
Setpatch
Work:Games/FPS/DOOM/
DOOM1/
Stack 20000
DoomAttack
Then the first DOOM game will run. Typing DOOM2/ or UltimateDOOM/ will let you play those games instead. I hope everything goes smoothly for you, and for anyone else who wants to try DOOM on their Amiga the easy way.
I have tested this configuration on several Amiga setups, and can confirm it works on:
A1200 + 4MB FastRAM
A1200 + 8MB FastRAM
CD32 + SX32 + 8MB FastRAM
A1200 + 030/28 + 32MB FastRAM
A1200 + 030/50 + 128MB FastRAM
Here is the link to the AmigaDOOM.lha file:
http://home.exetel.com.au/amiga/AmigaDOOM.lhaThe archive contains no copyrighted data, it's all made up of files from Aminet. I'm sorry I don't have a link to some sort of "DOOMwads.lha" file as well, so you'll have to find those yourself on an old DOOM CD or by purchasing it online. Or use the shareware DOOM.wad which is freely available.
