Hey! We have found this old cartridge under a desk in the library of Lapland. It appears to be for a system called "Emu 2.0", made back in 1978. These systems don't get produced anymore, and we can't seem to find anyone that owns one.
Thankfully we have the documentation for it, so maybe we can use it to write an emulator and see what this ROM does?
[Emu 2.0 Documentation.pdf](Emu 2.0 Documentation.pdf)
Write an emulator according to the given documentation and execute the rom file. If it works correctly, it will print out the flag. My emulator written in python can be found here.
flag: X-MAS{S4nt4_U5e5_An_Emu_2.0_M4ch1n3}
