Descent for Rockbox
« on: August 06, 2010, 05:36:44 PM »
We can run Doom so I don't see why Descent couldn't run. It might be a 6 DOF game, but I don't think it's any more "intense" than Doom, and not only that but most functions could be emulated. I'm not real big on the controls, but maybe (I'm using a Sansa Fuze v2...so this is in description for it) - but like the up, down, left, right keys for "scrolling."

I'm not sure about button combining - but maybe using the 'select' button and arrow keys would then shift the view to emulate the 6 DOF. Then just select to fire, and scrollwheel to select weapons?

Has anyone even heard of Descent? Please tell me - I'm not the only nerd here who has heard of it.

Because its not open sourced under a free license, which makes running it in rockbox impossible.

It is open source... there are several projects which had the source to make Descent use Open-GL or become "HD."

EDIT: http://www.descent2.com/ddn/sources/descent1/

Missing:
Sound
Modem (Unimportant)

Those parts are © by 3rd parties.

It needs to actually be under the GPL, not just "open source" in general.

Could you define the difference between GPL and Open-source?

In the meanwhile, here is DXX Rebirth - or Descent Rebirth. It's Descent (with sound), in high quality [though that may have to be downgraded] even with HQ sound! It's also GPL licensed. :)

Thank you Chronon. I came right out thinking that this would be just like Rockdoom - create a loader, and you'd need some or all of the original games files. I am inquiring with Interplay however.... has ANYONE besides me ever played this game?

Yes, and since you need pitch, yaw, rotate, and two-axis strafe plus weapon switching and throttle, there's really not a player with enough free controls.

Well I wouldn't think every function is ABSOLUTELY necessary to be made working. But is it possible to combine two button presses to make a different function work like.

Button 1: Action 1
Button 2: Action 2
Button 1+2: Action 3

Sample "cloud" controls:
I'm not real big on the controls, but maybe (I'm using a Sansa Fuze v2...so this is in description for it) - but like the up, down, left, right keys for "scrolling."

(by cloud controls, I'm referring to I was thinking about this, no certainties as I'm not a programmer.)

You're not alone - I also played Descent and own the original disc.  A great game, but it never really captured my imagination for some reason.  Also, as I recall, some of the game induced pretty heavy vertigo for me - very odd as I have always been highly resistant/immune to that sort of thing.

Funny, you should mention Vertigo. It's an expansion pack. xD

I contacted Interplay, just hopefully they'll respond.

Apart from the obivious problems with the controls... I think with a 6 DOF game you would lose orientation fast on such a small screen.  :-X

And even if the CPU is fast enough, isn't memory an issue? I remember that Descent came out about two or three years after Doom and required something like 8 or 16 MB of RAM. How much does the Fuze have?

If I had to guess the RAM of a Fuze, it should be 16 MB and 32 MB.

The E200 series has 32mb and I think the Fuze is equal or a little weaker.

The Fuze V2 appears to use the ESMT M12L64164A-7T chip, which is 4MB

Using PMs to annoy devs about bugs/patches is not a good way to have the issue looked at.

Thats actually the fuze v1 you're thinking of, and the M12L64164A-7T is a 64 Megabit DRAM, which works out to 8 MB.

Regardless, this is not really the right place to talk about what old DOS games were like.
