I have acquired a few developer Roms for Game Boy and Game Boy Color and believe a few of them to be extremely rare. Is there anybody who could point me in the right direction for getting them valued.
I have about 25 of these rare roms, brought from a friend many years ago and due to the fact that there are only a few in existance I am finding it almost impossible to find out their value. Nearly all of the roms are on Grey Cartridges, with a panel missing from the back, where you can see the insides of the cartridge including the battery.
I have no idea if they are still working, but can probably find a console somewhere to test them.
The three carts that I am most interested in pricing are as follows:
Metal Gear Solid GBC
Resident Evil Preview Code
Resident Evil Gaiden Review Code
I do hope someone can help me find an expert to get a reasonable valuation on these rare gems.
