Even "simple" games that require 4 inputs at the same time (button 1 + button 2 + up + left, as in your example). Similarly, PC gamers only really use 2-3 keys on the keyboard at most (WASD for first person shooters, etc).Įmulator players generally hit this wall pretty quickly. Typists are generally only going to be hitting 2 keys simultaneously at worst (SHIFT+somekey), and system operators maybe 3 (CNTRL+ALT+something, etc). On a standard keyboard, this isn't really an issue. The downside is that you greatly limit the number of simultaneous keys that can be pressed to register input, usually to 3 inputs at a time. These days the tradition continues (and we see the likes of keyboards that cost single-digit dollars). Particularly back when PCs were young, saving money in any way was a good thing. Using a matrix, you reduce the number of needed wires down to about a dozen. If you think about it, a standard 104 key keyboard would normally need 104 wires (plus a ground loop) to get signals from every single key back to the controller circuit. The theory is that you can wire the keys up on a matrix (ie: a grid) so that essentially the X and Y co-ordinate of the key is enough to determine the keypress (it doesn't really work this way, but this is a simplified example for the non-technical). This is done entirely as a cost-cutting measure. Standard PS2 and USB keyboards have a limited number of wires connecting the keys to the controller circuit. Get yourself a USB gamepad/joystick, console joystick with USB converter, or proper non-blocking input device like an Ultimarc iPac or GroovyGameGear KeyWiz to avoid it. Yes, this is normal for a keyboard, and is called "key ghosting". Sorry if it's a silly Q, but little niggles (not knowing) like this really annoy me. I have a feeling its because too many buttons on the keyboard are being pressed at once but i'm not sure. Is this how R-type (and other shmups which I have downloaded on MAME, such as Darius) is/are meant to control (is it same on Wii)? Or is it a problem with MAME? It's annoying with games like Darius because I like to hold down fire and bombs at same time but movement is then restricted. This restricts movement when trying to evade enemies/bullets. When I press and hold button 1 (Ctrl) and button 2 (Alt) simultaneously, I have found that I can't move in all diagonal directions. However, i'm a bit confused with the controls. So I was going to download R-type from Wii VC but decided to try it out on MAME first. I didn't really play any classics so I thought I'd play them now (Ikaruga for GC has got me into shmups recently). I used to play the odd shooting game as a kid but unfortunately I didn't really have any standards back then.
