This game works with: Mini vMac

According to developer Bill Scott, "Gato was the #1 selling Macintosh game for a couple of months and top ten for a year." He further discusses its creation here and here.

"In Gato, you play the commander of a United States submarine in the Pacific Ocean during World War II against Japanese warships."

"Gato is a 3D real-time submarine simulation game. Gameplay consists of missions where the primary directive is to navigate your submarine to track and intercept (multiple) enemy warships (patrol boats, destroyers, etc.) on the randomly created map and close in for the kill with torpedoes.

Combat itself consists of a direct visual of enemy ships (via periscope) and firing torpedoes at the correct angle to ultimately sink the ship. Be warned that although you have the element of surprise, enemy ships can fire back!

When all hell breaks loose, an identified submarine is a sitting duck to those Japanese guns. Be prepared to direct your damage control team to fix up your damaged submarine ASAP! The mission ends when you have successfully eliminated all targets in the map."

Architecture: 68k

Must be booted from an 800K disk.

I've uploaded a more complete archive featuring 24bit's disk image and everything I was able to find on the web related to GATO.

BTW, that splash screen with the big cat's head on it actually doesn't load with the current disk image; I used Graphic Converter to make a .jpg of the startup screen file.

UPDATE: Now available is a new archive combining the earlier files together with a later, non- copy protected version of GATO and some more related documents.

UPDATE: I've replaced those weird hacked version splash and publisher screens with the originals from the unhacked version.

Thanks for the bootable image, it does work with Mini vMac, though like many very early games, it crashes the Plus (or at least Mini vMac) on exit.

There's some really weird "Swiss" and "no copyright" information in the game's files, I'm guessing it's evidence that the game had to be hacked for copy protection.

Thanks for the 'bootable disk image for Mini vMac', I'm sure it can replace the current 'official' download.

I've added a .jpg of an advertisement extracted from the Computer Gaming World Museum:

Yeah MCP, the artwork is awesome, very impressive for a little game. But well, this CAT doesnt work with my stuff either...

The original system file was missing. I kind of fixed this by copying a System3 file to the image.
Not working are the splash screen and shutting down the game without crash of MiniVMac.
The game is working though, as I was told.

Anyone have the original disks?

I will not have the time tonight, but I may well be trying MESS in a few days, has it seems it will become a viable Macintosh emulator in a near future.

This archive is a number of floating files; if you're getting only one file then something is corrupted or not unstuffing properly.

On a side note, on rare occasions when something doesn't work with Mini vMac, I'm always curious to know whether it works with MESS, which I'm unable to run myself. Anyone feel up to trying it on MESS?

I compiled a Mini vMac Mac IIx and installed Mac OS 7.5.5 on it, but when I try to extract the content of the archive found here, it gives me a single file that cannot be proccessed anymore (not an archove and not an executable). What should be it's type and creaor ?

Has anyone had any luck getting this to work with Mini vMac? It's not uploaded as a bootable image, and I can't seem to make one that works with these floating files for some reason. I'll try again...

I love the artwork that adorned some of these early Spectrum Holobyte games like GATO and Falcon. Looks like a sculpture but by whom I don't know.

ADD: The "backup list" included with Copy II Mac mentions a GATO 1.2 and 1.3; this one has no version number that I can see and is dated 1985, so I'm guessing it's the first version. Maybe it doesn't like the Mac Plus. Has anyone else had any luck?
