Few years back we had PCes what weren't as powerfull as GP2x is. So I would say that GP2x is already such machine to an extent. The whole box just replaced by one small chip... SoCs at one moment might treaten the classical PC business. Why purchase big, not portable, hardly noiseless, power...

That's very good idea! There is place for two extra AA and it could arranged that way the GP2x would still be able work on just 2 of them. Actually you don't want this - trust me. It's almost completely dark without backlight. Tested it by accident. :) Faster cpu would mean change of...

Software fix for GP2x's joystick? That was dicussed long time ago with two developments: - DaveC's biasing schemes - my software routines for filtering stick's events in time domain ("timegate") Actually some apps have implemented DaveC's schemes.

Better stick/dpad. Progressive refresh for LCD. External control for volume and brightness. Two SD sockets. 128MB of ram.

Please... calm down. Not that it isn't possible but it would need connecting wires to one of four GP2x's buttons. Which one? (every game will have different controlling schemes) And doing it (beyond the main function) will need soldering as only GP2x's stick pins are so easily available. For...

Even better - the µC version will have two pins left to other uses. And it's reprogammable as I will be using flash based µC. Not that I will not produce the 4067 based ones as well or the my firmware is bad. Actually it's quite fast and current drain can go as low as 12µA. But I might imagine...

But if Heinz could have such power then what it'd be stopping it from demanding buying a new fork for every different bottle of Heinz's ketchup? You gave a finger - they will take a whole hand later.

I think we might speculate with high degree of accuracy what 3D capabilities of XGP will have. It has 32 bits wide DDR data bus to the memory. The bandwidh should be twice as big as in GP2x (what is using SDRAM). So 800-1000MB/s. It should (if 3D chipset is capable of it) be able to fill...

Yes of course if he will be interested. I'd prefer to sell via established shop. Logically. :) Mine implementation of QD dpad as simple allows all four switches push down. It's interpreted by converter as center push. At the beginning I was hoping that I would find a proper 4 microswitch...

It's just a hole what was drilled in a place of the original one (the one for stick's bar). Yes - I was using triangle shaped file (ugh - was calling that a chisel before - my mistake sorry) what have increasing diameter: Just putted it in original hole then was rotating it slowly...

In range of 25-35$ including everything. Perhaps less. (the PCB will have solder mask) Final price will be set when the ED will get the final units. :) You don't have too. Look at the ebay.com - there are QD keypads including dpads. I can buy them from UK for 2 pounds. If you can for less...

Another difference is that with cartridges you are owning something physically. You can sell it where it isn't always true for software licences. You can do with it everything you would like too (drill holes for an example :) ). IMHO technology got good enough to provide us with very small...

Yes and long time ago. I showed that, didn't I? If not then sorry and: closer to the QD: The QD dpad fits as it should. The problem is that whole construct (the stick base, contact PCB and the shim plus QD itself) is a bit too high INSIDE the GP2x. So case can not be closed without tension -...

I'm too because it needed a change of mainboard PCB. If they were willing to do so then it means (probably) that there are some other changes as well. I doubt that GPH would change PCB design just for that stick.

Just NO! Look: The GP2x's stick has two parts - the top and the bottom. The top can be removed and the bottom will serve as mounting socket for the new controller. That was my idea from the start as it doesn't need soldering, it's firm and stick's pins are preserved allowing solderless...

Yes... you are right. It was my reading mistake... But for me the original GP2x's screen is sharp - I can see easily every pixel or even subpixel. It's all looks like different gamma/brightness settings for the new LCD. And for sake of curiosity is there explanation what is causing the...

Except that you will need to lower (by sanding) the bottom part of GP2x's stick by 0.5mm. I will try to minimize that using for the contact pads' PCB as thin as possible. It is easier to do than drilling the bigger hole in GP2x's front panel anyway. And making a hole in GP2x's front panel isn't...

The "DRM" is not needed. The technology will soon provide us with flash based memories in GB range at very decent prices. Make them read only and in very small and convenient form. There isn't a reason why tens of them couldn't be putted even in handheld like the GP2x. Even better - add some...

Please look at my latest latest updates about the stick replacement. I can now (via some other company) manufacture decent printed board circuits (at decent prices even at low quantity). :) Even double sided with metalized vias if needed. Nothing special really but after making boards in...

For the stick - it's better to have ordinal bias than diagonal one but rest of its issues will remain. I'm puzzled why GPH didn't go further with it... It needed PCB change so they could as easily mount something completely different. For signal compatibility a SMD demultiplexer would get job...
