Expert Help Needed - Rare Game Boy Colour developer roms
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.
Depending on the build of Resident Evil you're looking at a fair amount of money. Two builds were recently released to the public so if yours happens to be of the same build it could cripple the value of the cart. However if it happens to be something unique you could be looking at anything up to the $$$$ range. Don't get excited yet though, it really depends on exactly what it is you've got. It you want to get an accurate price evaluation it would help to provide some info on the games, maybe even some pictures, it would help determining exactly where in development they are, i.e beta code or final code etc as that usually determines their value range.
Gameboy carts can go for as little as 50$, and go up to the hundreds or thousands of dollar range, depending on the title and the version. As mentioned, more information is needed to make a fair valuation.
The carts themselves are not the valuable part, its the data on them.
Thats why you need to catalogue the differences

Maybe start off simple and give us a list of all the games you have?
Pretty much this. The more you can say about the builds the more accurately they can be valued. Generally builds which are identical to retail aren't worth very much money, maybe $50 - $100 at the most depending on the game, but preview builds are often worth a lot more and typically it all depends on how they differ from retail, the more popular the game and the more differences to be found, the more people are willing to pay for it.
