You cannot understand the Neko Project II code without understanding the hardware it is emulating. The emulator is essentially a software implementation of the documents below.

This is where Neko Project II Android shines and frustrates. PC-98 keyboards have slightly different layouts from modern PCs (e.g., the "¥" key, "Kana" mode). Here’s how to set it up:

As an emulator translating instruction sets in real-time, CPU usage is moderate to high. The app does not aggressively throttle CPU speed automatically, meaning users should expect significant battery drain during extended sessions unless they manually limit the emulated CPU speed in settings.
