GAMEBOX Multi-Game Platform TV Video Game Console -MAME-
neninef:
So.... Noone trying to debug this anymore?
MicroSD will only be used for GBA and videos and usb ports only for the Keymax controllers?

From the pics its running off of a Ingenic JZ4755 SoC
Grab a datasheet, and start playing. (I've attached one to the post)
So would be similar to the A320 (as its same family) - its the same cpu as in the A380 Dingoo device.
Some tools here for those.

You may find the rom repack tool works for playing capcom stuff - someone should check.
It has USB, but no idea if hooked up, I'd guess not if you say its SPI based.
Without looking at it physically, I'd say it would be fairly straightforward to port the A380 stuff onto it, as its mostly the same hardware.
I reckon I could probably get it running an embedded linux fairly easily, as i have a little experience in reverse engineering stuff ;)
I also speak / read Chinese semi fluently, so thats a help too :lol
Its documented pretty well though, I'd probably start looking at the uart and see if it pokes out some data on boot or not.
Someone should probably pull the nand flash out and dump it, then I could tell you how it ticks...
Actually it wouldn't be too hard to design a MAME machine based on something like this - making boards isn't $$$ anymore, and with SoC based stuff like this, its more or less 20 minutes design change from a reference design.
Getting a BSP from somewhere is the main issue though..
I do like it when work and play intersect though, so i may take a closer look at this..
A quick google shows that there are people working on OS stuff - the RTOS people for a start -
Its mentioned here -
http://code.google.com/p/rt-thread/source/browse/trunk/libcpu/mips/jz47xx/jz4755.h?r=902
And a closer look at the Ingenic site shows they are nice - http://en.ingenic.cn/product.aspx?ID=62
The BSP is freely downloadable, so this would be fairly straightforward to code for I'd say. Much easier than the usual stuff I have to do!

Cool, man. Is it possible to get RGBS video from it though? I would happily get one if it can be fitted with a JAMMA edge connector and set to boot right into a specific game of my choice... :cheers:
shanghaiguide:
I don't have one, and I couldn't find it in the local mall, so I guess this is theory for now.
Spec sheet shows YUV though, so we could make RGB from that, however we don't have a sync line, so no rgbs unless we can use gpio or pull from the lcd hsync / vsync.
Board design guide attached.
BobA:
Here is another game console from DX. Right off the bat it looks like composite video not component. It says it can have a USB memory device attached. Supposed to play games with the gamepad. Again a non standard pad.
Yet another DX game box
