Thank you again.
I am truly honored—this is the first time anyone has praised my work so highly.
First, I would like to confess that this game is not actually running on real hardware or an emulator. It was developed using the Godot game engine, purely for modern PCs.
However, I created it with great care to faithfully reproduce the look and feel of a real system, including the graphics, strict 8-dot scrolling, and authentic PSG sound.
In particular, the in-game music uses the NDP Demosongs published by Naruto-san. Since the audio was generated by a real MSX PSG driver, it can truly be considered genuine PSG sound.
