since the PP is running on a dragonball processor has anyone outthere tried hacking it and even possibly overclocking the device.. (ya I know it will void warranties etc.) but it looks like it is very possible if I swap out a few items from some palms and IPAQs...all sorts of things would be possible with greater memory and screens that take 24bit color

It's easy to use any IR control software at your palm or iPAQ than to hack PP or migrate its firmware. Also, you can use PC/MAC IR/IRDA devices like RedRat2 to control AV equipment from 24bit PC screen and develop your own control software based on its API.
And - what you want to hack in PP?
Also - what is the interest to overlock it?
All current CCF are less than 50% of its memory.
24bpp for passive matrix LCD is dysgeusia; and this processor is part of this screen!

You would also have to build a program and emulator that would allow it as well. Pronto edit would let you put anything other than what it allows now into a Pro. But it would be cool

1. I want to increase screen resolution to handle 24 bit color bitmaps
2. When you increase from 256 color to 24bit the data increases at minimum 3 fold and with 8 megs you will run out quick so I want to increase the 8 meg to 32 meg chip
3. Since it is a dragonball processor (not sure what megahertz it runs at but guessing around 25 or so)and in the past I have had great success overclocking in other handheld devices I feel it will be necessary to handle the increased graphic abilities and swapping between large 240 x 219 bitmaps in 24 bit color

To answer your MHz question. It's just a click away......

The display processor is built-into the Dragonball CPU, so it would be impossible to make the CPU in the Pro do any more than 256 colors. It would need a new CPU, new circuit board design... ie., a whole new remote.

Now that sounds like a pretty good idea.

What about scan-line interrupts?

The old Atari 2600 was only capable of producing 16 colors, but inventive programmers eventually learned to replace the color palette after each scan line, thereby allowing 16 color per line. This gave way to another inventive technique whereby the program logic poked new color values into the palette after each "missle" (also called a sprite) was drawn. Skilled programmers could use this method to coax 128 colors out of the venerable forerunner to the 6502 processor. In the twiligt days of the 2600, some programmers combined these two techiques to throw as many as 4096 colors on the screen.

These same techniques have been recreated on dozens of devices since then, but I have no idea if the ProntoPro could be talked into it. Since the ProntoPro palette is not entirely mathematically based, I have to assume that the color values are definable. In that case, at least one of the above methods should work.

All that being said, I seriously doubt anyone is going to take the time to update the ProntoPro's firmware when I'm sure Philips has to be working on a successor to the ProntoPro anyway.

If it was possible, perhaps someone's done it with a Palm?

Probably would make it twice as slow, though. :-)

The Pronto 256 color palette lies at firmware, and you can change it if you want (send me your palette and device model - I will answer you with correct firmware with this palette). I have tried to use custom palette - my belowed green-fade-to-black-fade-to-orange - it works.

I think that this screen/processor NOT suppots true 24bpp, only 256 colors at once.

Also, I doubt, that there is no any scan-out at this LCD built-in device used...

Eigeny Oulianov: are you going to build an other cool tool to take care of that (like the font tool or the icon tool?

I will do it, but now I spends my time to finish "Pronto IR formats" opus, until it is actual :))
My English is too ... slow.

When poking around for software for my Clie 615, I did once come across a program that allowed scan-line-based palettization for some other Palm-based PDA. Since it wasn't my model, I didn't look any further. I'm pretty sure I saw it on PalmBoulevard.com.
