## SolutionAfter unpacking the archive we get a file named `VirtualRam`, using `file` on the file gives us.
```bash$ file VirtualRamVirtualRam: Game Boy ROM image: "VIRTUALRAM" (Rev.01) [MBC5+RAM+BATT], ROM: 1Mbit, RAM: 256Kbit```
So a `Game Boy ROM`, we need to find a fitting emulator, best with debugging capabilities. [`BGB`](https://bgb.bircd.org/) is exactly what we need for this job. After opening the ROM we can start a new game.

We can't do much except talk to the `NPC` which will tell us `It's dangerous to go alone - View the VRAM`. All right, then we should do so.

And horray, there is the flag, lying unused, and a bit scrambled, in `vram`. After reordering the tiles we get the flag.
