You are able to track your collection easily- simply tap the row and the text will turn green, never buy a dupe again.
Notes can be added to each game so you can easily see if you need the instructions, box etc, or you can enter and save your high-scores!
Also added is a hardware section that briefly details the various revisions, with dates of release and games in each type.

The forerunner to the incredible Gameboy series of systems, the game & watch took the world by storm in the 80’s, being the first of the hand-held systems to really offer gameplay beyond a few flashing lights.
Nintendo created versions of many of their classic franchises, such as Donkey Kong, and even Zelda.
This database of all 60+ games that were released is ideal for when browsing at your local flea-market or video-game store and is sure to bring many memories flooding back!
Each entry gives details of the release date, a picture of the game so you can decide if its ‘your type’, the serial number, as well as rarity and value guides just in case you should find one hiding up in your attic and wonder if its going to make you rich - and if it’s the ‘famicom’ version on Super Mario Bros, well then it just might!
Also includes a direct-search button for Ebay - press the button and you are taken directly to eBay with the search results displayed! Ideal for when you need to quickly check up-to-date prices, perhaps when trying to bargain with a store-owner who thinks because a game is 25 years old it is worth a bomb!
