Handheld hardware with small cartridges

[pulkomandy]

Hi there,

So, I bought this device recently : http://www.alibaba.com/product-gs/457838238/PNP_Game_player.html

It's a quite nice handheld Famiclone. Here are the infos I gathered so far :
 * 4MB on-board flash memory with "50000-in-1" menu (30 actual games)
 * 2MB flash memory on cartridge with "999999-in-1" menu (35 actual games)
 * 32K RAM chip on-board

I'm trying to find more info on the device. It seems that there are other similar handelds from Shenzhen Nanjing using the same cartridge kind. The cart has 50 pins (25 on each side), 1.27mm (0.05") spaced. They seem to connect more or less directly to the flash chip. I'll be looking for the pinout and try to dump the flash.

Anyway, I'm wondering if someone got his hands on such devices, or even heard of them. It looks like it could be based on the VT02 chip, since it seems to use "OneBus" external memory (the lack of mapper out of the black blob circuit and the fact that the cartridge PCB is labelled "16bit" hint to that). But it could be some other strange design with the flash used as PRG ROM and the internal SRAM as VRAM, I'm not sure yet.

A list of games :
Internal cart:
 Super Mario 3
 Super Mario 6 (hack of Looney Toons)
 Upin Ipin (hack of Mac Donalds Land ?)
 Super Mario 10 / "Super Bros. Kung Fu Mari"
 Super Mario Bros
 Banana Prince
 Bubble Bobble part 2
 Kick Master
 Abarenbou Tengu
 Astyanax
 Power Blade 2
 warwolf
 Panic Restaurant
 World cup Soccer
 Ms pac man
 Spartan X
 Burai Fighter
 Sqoon
 1942
 Bomber Man
 Mappy
 Arabian
 Dora Bros (mario bros hack)
 Baloon Fight
 Clu Clu Land
 UFO Race
 Star
 Pooyan
 Road Fighter
 Excite Bike

Cartridge (menu shows JB223016 on the bottom, any hint what it could mean ?)
 Crash (Disney Jungle Book hack)
 Mighty Final Fight
 Snow bros
 Contra
 Aladdin (not the ones already on the wiki, it's some green guy on a flying carpet. No title screen or whatever)
 Adventure Island
 Bomberman
 90 Tank (Battle City)
 dr Mario
 Macross
 Super Mario
 1942
 Lode Runner
 Mappy
 Mario Bros
 Milk & Nuts
 Millipede
 Muscle

 Pooyan
 Popeye
 Sky Destroy
 Space ET (space invaders)
 Star Force
 Urban Champion

 Seicross

 Soccer

As you can see, there are some duplicates between the cart and internal memory. I think I'll try to hack the cart to replace these with some games that are really missing (like, any Tetris version).

I ordered a connector that will help me dump the cart. For now, I'm looking for any information about this device, and the games inside. Any help welcome !

Dora Bros is a Japanese fanmade hack (and its Doraemon not Dora the Explorer), you can find the ROM pretty easily if you search for it.

i realise this is a pretty old topic but it's interesting to note they were still using flash memory on the cartridges in 2012 models - later similar consoles just have completely fake carts that trigger a different set of built-in games.

FAST EDIT : Upin Ipin too! i hope that not a lazy title screen hack  O.o
