It is an application that manages retro games (FC).

Did you have this when you were collecting retro games? Next door
After all, there are many cases where you buy it in duplicate, so
I made a management app.

Since the game list is prepared at the beginning, basically search
All you have to do is register the number of possessions.

・ You can add games that are not on the list by yourself. The added data can be deleted.
・ Since there is a memo for each game, you can record the date of acquisition and impressions.
・ By registering the number and amount of money you have obtained, you can manage how much you have used so far.
・ Images can also be registered.
-There is also a wish list function.

* The image is compressed to a smaller size to reduce the capacity.

* The game list is created as far as you can understand. I think there is something missing or wrong. note that.

* Backup outputs data in JSON format. Please save the image separately. (CollectionFC folder in DCIM folder)

* Enter the number of new acquisitions as a minus, and if the number of possessions becomes 0 or less, you can exclude it from the possession list.
