GP32 Gp32>mouse


Not sure that would work would it? The GP32 stick is digital microswitches so it's not like the movement of an analogue mouse at all. New software would have to be written for such a GP32 mouse in the future wouldn't it? It would certainly be nice for mouse based games but defeat the point of a handheld console if you have to prop the GP32 up like a screen and set a mouse up. Some sort of built in trackball would be best, maybe in the GP32 MKII eh?

I'm surprise no handheld (as far as I know) has had a trackball incorporated - Something along the lines of one of those tiny thumbballs you can get for laptops would be excellent...

Shirohagen - you could use it to simulate the joystick - don't forget a mouse isn't really analog - it just generates digital pulses in the same way as a joystick, just at varying speed - what is analog is the movement you see on the screen.

hmmm but a mouse can move at many more angles than a joystick. I think that's what he meant anyway :p
Anyway, I'm glad at the response to this, the things I think that it'll be best for is:

FPS (Quake!!!)

scummvm

Shotting games on the NES (it takes the place of the light gun, not sure if that can be done thogh, infact no because you don't see the crosshair, forget that)

Shooting games coders could make (with the new 3d engine who knows what House of the Dead/Time Crisis Clones could be made!)

Anyway..
carry on

A mouse just moves up/down and left/right, it just varies how much each way. Open a standard ball mouse and have a look.

hmm true you're correct there. But the way I was kinda going was the concept that the mouse surely demands different coding. And those mini mice are optical (well the ones I'm on about) so does thta make any difference?

You probably could figure out the pins on a serial mouse and have it wired into the d-pad stuff. I remember a company (mashmods??) that would add in an external Genesis pad or SNES pad to the GP32 by doing something like that. Couldn't be too much harder for an old PC-style or Amiga-style serial mouse*.

*Full disclaimer: I don't know crap about electrical engineering.
 
Any mouse will only convert the movement of the ball into X and Y movements. In a ball mouse, the ball turns two rollers with little wheels attached, which simply trigger pulses of X and/or Y. You could wire the sensors to the joystick inputs - it might not feel exactly right, but with some tuning it would actually work...
 
I think the best option would be to use the USB port, and write a mini mouse driver to read an MS Mouse. Nearly all mice these days can emulate an MS mouse and you could probably deconstruct an old DOS MS Mouse driver etc.

Regarding the differences between optical and Mechanical, the output from the actual mouse is identical. All mice just send a stream of data down one line, you just need to know how how to interperate the data recieved!

The practical upshot is, it shouldn't be too difficult. The downside is, the GP32 is a handheld device, and to use a mouse, you need a surface. So a trackerball would be a better option, and a trackerball is only an upturned mouse!!!

TTFN,

Trackballs are compatible with the same drivers...

Yep, they are. After all, they have exaftly the same mechanmisms as mice do!

imagine a little trackerball on the back of the gp32 then. Like they used to have on the old laptops. That would be great.

I still feel it'd be easier to connect a mouse using RS232 serial than USB, since on nine-pin you have different pins for up, down, left, right; be a solder job in seconds (into the joypad wires) and no software required.

But yeah, a trackball is a much better idea, or one of those "keyboard nipple" things like they have on some laptops these days.

ahh yes one of those things would be cool to. But the accurcay of a trackerball would be much better. One coming out a tiny bit of one of the gp32's lumps would be great.

If the mouse had a powered USB connection it could be done. Or if you could make the GP power its USB connection. would be handy for ST stuff...
