Gameboy cart writer?

Is this a cart writer? Is it an official bit of hardware or what...may buy it to see. Anyone know anything about it as I cant find any info, just what little the guy who has it says?

 

Yes it's official, it's a DMG Flash Gang Writer.

 

Interested in the pile of carts that is in front of it really. What do you think this thing is worth?

 

A lot, it's unclear however what is included in the lot as it's just in a pile but. Looks like about $750 of hardware, more depending what is on the carts.

I'd break it down like this:

~20 x GB carts ~ $400 (to $600...)
DMG flash ~ $100 (maybe too generous)
Wideboy 64 if CGB ~ $75 / if AGB ~ $120
2(+) x GBA carts ~ $120

 

Wideboy, I was stumped as to what that was, I knew I had seen it before! Cheers for the info Kyuusaku

 

"2(+) x GBA carts ~ $120"

Are they GBA? I will not remember right now. But it looks like gbc flash

 

Yeah the black ones with tall protruding PCBs for SMD ROMs are GBA.

 

Or less maybe if the carts were all review versions of 3d0 games such as Army Men 2 & Might & Magic...
