I'm a big fan of handhelds and the Gameboy line. I've bought almost all of the standard Gameboys when they were initially sold in stores. The Micro is my preferred system for GBA games. I'm still impressed with the design, the screen and the size. The Micro is close to double the size of a GBA cart and yet the cart doesn't even stick out when inserted.
You can't go wrong with getting a GBA SP ags-101 since it plays the older games too.
I'm also interested in hearing more about swapping the original GBA with replacement backlit screens if anyone has any experience with them. Is it as simple as unplugging the old screen and plugging in a new one? I still have the old Afterburner front light kit installed in my original GBA. Not great at all by today's standards but it was impressive 15 years ago.
The emulation is good, but even though it has the same control layout as the original SNES, it's difficult to play action or platformers for some reason.
What model do you have? I don't recall if later models improved it, but the original PSP-1000 has a lousy d-pad. It's given me problems acknowledging diagonal inputs, for instance.
I totally agree, my psp-1000 dpad is pure crap. It's stiff and diagonal directions seem to not fully register at times, making fighting moves (quarter circle moves) almost impossible to pull off. Even playing a simple shooter like Gradius Collections is quite a chore. I think the level of how bad the dpad varies with different psps since I've tested a friends psp-1000 and the dpad was a little better than mine.
