Any Ds Emulation News?

[fearofshorts]

Yes! Perfect! All we need to do is work out how to fit the Pandy's widescreen view on the DS's screens and we're set!

Now that's not saying I wouldn't mind seeing DS, Saturn, Dreamcast or PSP Emulation (Heck, we've seen videos of those last two running on a Pandora, so it's been in development in the past) But honestly it's hard to imagine a full speed emulator of these on a Pandora because we aren't even there yet on the hardware the emulators are currently developed for.

Actually, I doubt that there is a video of PSP Emulation yet. However, you are right about Dreamcast - but it didn't look too playable neither.

However, PSP Emulation is a lot easier if only the actual software and not the hardware itself is emulated. Basicly it's a heavy abstraction which is possible because the PSP has it's own OS which the software depends on. The functions of the OS are always the same and can be optimized a lot.
The DS on the other hand is programmed at a lower level as far as I know. The developers have direct hardware access. Additionally you have to keep the 2 processors in sync and it's timing critical meaning you have to emulate the CPU in greater detail.

(Not exactly sure about the DS, and no idea about the DC - take all the info about those with a grain of salt)

is it true that since the DC doesnt have a screen that the pandora cant emulate it?

You're forgetting the VMU. Never in my life have I seen such a display of ignorance. :angry:

We need to figure out where to put those four screens.

That's easy. You just display a scaled down picture of the entire Pandora screen on the DS touchscreen (next to the virtual keyboard and virtual nubs) and use that to pan the upper display.

Start coding!

Wow sarcasim haven!

All kidding aside, there are some solutions to get the DualScreen configuration.
The obvious is by exporting the non-touch screen via TV-Out and using the Pandora's screen for the touchscreen part.

But that would be kinda redundant that it isn't portable (requires a TV/screen) so the next best solution is something like this:
First
Second


The "Star Icon" toggles between which screen to maximize (double its size) making the other one the original pixel count. This is because some games favour the use of the touchscreen while others focus on the normal screen, so configuring between both states in-game would be the ideal situation. This was for the N900 but the concept can basically be applied to all WVGA or 854x480 screens.

you might be able to play, say, phoenix wright at a decent speed if someone put a lot of effort into it

Oooooooobbbb... jeeeeeee...... ccccccctiiiooooooooooooonn nnn nnn nnnn.

Also off topic: Exo, is it true that you have been part of the developement team for Desmume? Nice work, if so. But it still needs a few disabled-by-default speed hacks (yes, hacks. I know it's well optimized) for all of the people out there still using bloody No$GBA.

If you haven't ever worked on it... I just embarrassed myself.

I don't have anything to do with desmume outside of harassing its authors. I don't think it needs speed hacks as much as it'd benefit from faster code, "well optimized" is not exactly how I'd describe it.

I can't wait for when people stop pushing the stupid "how do we fit the two screen" joke because every single time some genius comes around and takes it seriously and thinks he has a brilliant new solution for it.

I wish I knew more exactly what people meant when they said "playable" - although it's probably just what they'd tolerate, which is kind of a meaningless metric without further elaboration.

Do you mean that my next new perfect idea to fit DS screens on pandora is worth-less ?

I can say that my expectation are lower than DaveC's one But I cant see how this will help you
