There seems to be a lot of misconceptions and/or ignorance as to what's possible on the Touch. I see tons of messages asking if Game X or Game Y is possible. In most cases the questions are perfectly valid, but some of them ask for games on the iPod that just are not humanly possible. Sure, it's a great little machine and seems to be pretty powerful at first blush, but really -- it can't do what some people seem to think that it can do. Before those of you who fall into that latter category ask whether this or that game can be done, please consider the following facts: The iPod Touch has a 412MHz processor. That's all. A single 412MHz ARM11 processor. One core. A great chip for portable devices, but it doesn't hold a candle to desktop processors made in the last 7 years. Furthermore, it's a mobile processor. It's made to run on as little juice as possible so as not to drain the battery too quickly, and runs on a slower bus than traditional desktop or even laptop computers. This further degrades its potential performance. Rule of thumb: If it couldn't run on a laptop of the same processor speed, it won't run on the Touch. The iPod Touch does not have 3D acceleration hardware. None. Zero. Zip. Zilch. Nada. Don't even bother asking for a 3D first-person shooter made after 1995. Doom? Wolf3D? Sure, possible in a technical sense. Half-Life? SiN? Doom 3? You're dreaming. Rule of thumb: If it needed 3D hardware to play effectively on a desktop computer, it hasn't got a hope in hell of functioning decently on the Touch. The iPod Touch does not have any buttons. Well, that's technically not true. It has a sleep/wake button and a home button. Care to ask what these two can (and should only) be used for? If you said "sleep/wake and home," you get a biscuit. With that and everything above in mind, consider the control mechanism for the game you would like to see on the Touch, keeping in mind that every single game-button will have to be represented and used on the touch screen, and be large enough to stab at with a fat thumb. If you need controls for directionals, strafing, firing, jumping, crouching, crawling, weapon selection, inventory selection, and more to be available to the user at any given moment, then don't even ask. You'll have more screen area devoted to controls than game, and you'll need three hands or really dexterous feet to play. Rule of thumb: If you can't play it with an Super NES controller, and you don't have three hands or really dexterous feet, don't ask. The iPod Touch needs meat. The iPod Touch uses a capacitive touchscreen. That's a fancy way of saying it only registers touches when something that is electrically conductive (and of very low electrical resistance) touches it -- like your fingers. Or a sausage. This is different from most touchscreens you see on PDAs and smartphones, which use resistive touchscreens and can be touched with just about anything. What does this mean in practical terms? It means that, except for some fancy-schmancy stylus that can conduct electricity and has very low resistance (and I don't even know if one such exists), you've gotta use your fat, greasy fingers to stab at things on the screen. If the game you're thinking of needs fine accuracy -- like, you've gotta touch really small objects or control very fine things on-screen -- then unless you have fingers that terminate in a pencil-like point, control of such a game on the Touch will be wholly impractical. Not impossible, just frustratingly improbable. Rule of thumb: If your thumb can't control it properly, it ain't happening. And I really don't recommend sharpening a sausage to a fine point. ScummVM is not an all-purpose game converter. SCUMM stands for "Script Creation Utility for Maniac Mansion." It was created by Lucas Arts to aid them in writing game scripts for -- you guessed it -- Maniac Mansion. It went on to be upgraded, modified and used by Lucas as the basis for tons of other Lucas Arts games, from Monkey Island to Loom. But SCUMM games became increasingly unplayable on newer machines and newer operating systems due to incompatibilities, and soon not a lot of them could be played on modern hardware. That's where ScummVM comes in. ScummVM was designed as a virtual machine (hence the "VM" part) that could interpret and run Lucas Arts' SCUMM-based games on modern hardware. It was later upgraded to include support for Sierra On-Line's adventure game script engines "Adventure Game Interpreter" (AGI) and "Sierra Creative Interpreter" (SCI) which were used for all of the King's/Police/Space quest games, Leisure Suit Larry games, and others. To put it simply: ScummVM can only run games that were developed using Lucas Arts' SCUMM engine, or Sierra On-Line's AGI/SCI engines. It is not a generic game port engine that you can plug any game into and have it "convert" into some playable format. Those are called "emulators" and SCUMM isn't really an emulator, it just uses the graphics and sound from the original games and then interprets the scripts to run them on the native hardware. It is possible in the future that the ScummVM team may add support for other game companies' scripting engines, but that's up to them. If you really want to see a particular adventure game engine added to ScummVM, bug the team. If they do add it down the road, we all win.
