How do you unlock it? I tried entering and quitting "Free Mode" but it doesn't seem to work

For example like new meats added with different cook times and points. Multiplayer mode with friends like a real yakiniku experience. Sorry if im asking for a lot just that i really wanted a yakiniku game lol. Wondering if more stuff will be added

Where the hell is the bowl of rice, the kimchi, and all the other sides, meats, etc.?

My first thought was to have opened the game 50 times, but I think I have done that at this point and still don't have the achievement. My other thoughts were play 50 different games/rounds or to play on 50 different days, but I'm just not sure. I want to 100% the game and this is the only achievement stopping me. Does anybody know or have more ideas?...

It's the Membership Card one that throws me. I suspect it may require a certain number of game launches, but I have yet to figure it out.
