The best was soldermask removing part for a tiny traces. Nice pictures of PSP mainboard thought. Why it has so awkward design? Because of UMD drive or what?

It's ALPS RKJXL and yes - a PDF clearly states its operating life is 100,000 cycles. It should work longer thought. Manufacturers typically are giving the worst case scenarios to reduce warrants. So assuming average one cycle per 2 seconds and one hour use per day it'd have guaranteed life...

You can try to remove dust using can with compressed air. It works very well for that purpose. I have to clean radiators in my computer from time to time that way. It will be harder if you made grease stains. Then use some weak solvent (just water with soap might be enough) and clean rag.

I was making everything clear and there are some people what aren't afraid of it all. I made (many times) point of needed skill too. It's given - it's a hardware modification after all. Isn't that clear for you? And I made it using triangle shaped expanding file - there is info in this thread...

Downscaling at even ratios (2x2) isn't bad. At can be done very quickly even on just a CPU. You can do that way a subpixel scrolling for an example (and not I'm talking here about some LCD tricks). The Amiga can do subpixel horizontal scrolling. When the ratios are of whole numbers...

The MMSP2 is an asymmetrical dualcore machine. The 920T has more cache and MMU, the 940T has less cache and doesn't have a full MMU. But raw power of both is the same. It's an efficiency to utilize them well what is a problem.

Except my dumb mistake with not unconnecting LCD's ribbon cable and damaging it (easily avoidable) it's not hard to do. And polymorph stays elastic long enough to position a dpad. If not then there is always a hairdryer to longer available time. Or even repeat the process what can be done as...

Vertical scrolling for this one! Plus a motion blur (4xsub samples should be enough). Then text scroller just like in a PinballDreams but layered with saturated color addiction on the main playfield. For controls sidebuttons should be the best. Should run synced at every frame with some...

Even better - there some tricks what can get you close to 4x4 quality using only 4 subsamples. :)

"slightly incompatible" as in different resolution and memory size is a major difference. It'd could only work (to a degree) if all software would be 3D based but it's not a case.

This is a last (most probably) update as everything is ready. I will show how to mount dpad now. So... there is some of polymorph plastic involved what must be heated up to around 70 degress in a water: It's transluent then and elastic: It's time now to put a blob where the stick's base is...

I still have that Saitek DPAD what I was using once to test very first converter. If I will be in a mood then I try to rewire all its buttons to an µC. Then serially connect to the GP2x. Plus would be that no breakout box or no extra powering would be needed. Minus - a controller will have to...

There is also an other way to do this. It's hardware mood and unfortunately the GP2x's buttons pads aren't too easy to solder on. Otherwise I could just put a µC with more I/O pins and rewire everything. However as stick in the GP2x is really outputing 9 digital discrete lines so with some...

But it could be possible to add something extra. But how it'd be supported and connected? There are some possibilities, all not easy thought: - rip sdram chips and connected a FPGA to memory pads (it'd have to simulate SDRAM and have its external memory too) - intercept a LCD signal and add...

Not from Eorex. My GP2x has em48am1684vta sdram chips. They are in 16Mx16 configuration so 256Mbits each. Eorex has some sdram chips at 512Mbits but in different packages and working at different voltages. The MKII has Hynix sdram And if you will look what Hynix has to offer then you should...

And increase memory to 64Mb or even 128Mb. The GP2x proved that such niche handheld can have its audience. With such split for 3 modes GP is just confusing people. Arm cpu, enough memory, decent peripherals and friendly policy towards developers and it could have a chance.

So it was with GP32 and GP2x. The problems with XGP are: which, when and what kind of software support it will really get? Gamepark is planning to have 3 different technically models simultaneously and how they are going to get support for them is beyond my comprehension... The GP2x is a safe...

It will have to be profiled first to get a good idea of what it will be capable. 3D accelerator might be looking great on a paper but there weren't any perfomance claims yet. Arm alone can hande complex 2D games easily. Personally I'd prefer to have a faster CPU than a blitter. Air combat...

Now Gamepark has three version all with very different specs. I don't know but it's somewhat awkard, isn't it? Even Nintendo various handhelds have a common compatibility (the GBA series). Who is going to support all them?

I'd like also to add that the GP2x is unique because it has Linux as operating system. Of course I'm be considered a Linux "zealot" (but not that much really) however it allows much more functions to get of GP2x. For an exampe we have a Python what is usable to a degree. Try that on the DS. :)...
