Hi, I done some googling and reading but am still unsure how I should make my save "file", I was thinking about making a text file for readability, but what should I "save" into the file so I don't end up with a thousand differently save files. Me and my friend is trying to make a RPG-ish game (2D), so we got stuffs like health and inventory etc. How am I suppose to save my "inventory" into the file? for health I thougth about just saving it in plain number format but what am I suppose to do with the inventory? should I check each slots to see what item it is and save the said item into a a "Inventory" folder with seperated files as "Slot 01".txt with infomation about the item? I was thinking about just saving itemID but we decided to try to have "Randomized" items where they have a chance to have different component that grant stuffs(ex. Double jump).

When working with binary files, you also need to pay attention to endianness.

only if you change hardware

Always, always, always start with a version number.

I cannot tell you how many times I have had a bug report saying "load game broken". When I look at it the tester has tried to load a saved game from an earlier version of the game, something is in the wrong place and everything goes bang.

Always, always, always start with a version number.

Version numbers for the file, version numbers for the structures, version numbers for everything.

In quite a few projects I've seen a whole bunch of load functions, much like a factory. First it loads the version number, then a switch statement full of functions named LoadV1(), LoadV2(), LoadV3(), LoadV4(), and so on. Also popular are a chain of functions ConvertV1toV2(), ConvertV2toV3(), ConvertV3toV4(), and so on.
