Pocket game console?

Question

Game development

I would like that n64, ps1, gba, nes would be normally supported.
From the known ones:

1. OpenPandora
   
2. Sony Ericsson xperia play
   

What else exists from such devices?
(Now in stock gemei a330)
Thank you.

Answer 1

PSP same

Answer 2

For example, you can take an android tablet. Under it there are emulators of anything, even toys on a python, besides there will be an accelometer and the possibility of openGL 3D

Answer 3

The tablet is not very pocketable. And without physical buttons.
I have been interested in such devices for a long time, from those that are “on hearing” it can be noted:
1. Dingoo a320 - a little weaker than Gemei a330, but supports Dingux (Linux), for which there are many emulators and software.
2. GP2X Caanoo - more powerful than Gemei a330 and Dingoo a320, touch screen, various software, Wi-Fi, USB host. More expensive - it seems $ 120 on PlayAsia without delivery. The OS is not Dingux. I planned to take it myself, but now I think to wait for the release of Dingoo a380. I saw here on Habré a person who developed some applications for it. Sorry I forgot my nickname.
3. Playstation Vita - I think it can provide really good ps1 emulation (like PSP), unlike all other handhelds.
4. Not yet released Dingoo a380 - promise Dingux and different nyashki.
5. You can look towards Ritmix RZX - 50 (R480). As far as I remember, Dingux was promised in it. It seems that in a few days it will already be on sale in Russia.
PS1 emulation on all devices (except PSP and most likely PS Vita) is quite partial, some site about Dingoo even published a list of games that work fine. Pretty small.
GBA and NES are emulated with a bang by any Chinese under-attachment (thousands of them), judging by the reviews.
I have never heard of N64 emulators.
On this topic, you can look through an excellent site - a320.emulate.su, there are many reviews and articles, including reviews of devices that have not yet appeared in retail.
