Yesterday, we heard hackers had managed to expand the 30 game library of Nintendo's NES Mini.
But it seems Nintendo may have been expecting enterprising fans to take a crack at the microconsole's security - a secret message has been found within the system's code.
The message was written by an unnamed programmer under the alias of "The Hanafuda Captain" - a reference to the Japanese hanafuda playing cards which Nintendo once sold before breaking into the video game business.
Here it is in full:
The code was posted online by Twitter user bakueikozo (thanks, Kotaku):
Hackers have now been able to load their own digital images of NES games onto the NES Mini by breaking into its programming and uploading/downloading new data to a PC via USB. The device actually has a hard limit of 60 game slots, double what the NES Mini launches with.
It's not an easy method, however, and it risks bricking your NES Mini in the process.
