This is a 4K (four keys) rhythm game on Casio calculators fx-9750, fx-9860 and its series.
Press the corresponding key (7, 8, DEL and AC) when a note fall to the bottom of its column.
For the short notes (CLICK), you need to tap the keys. For the long notes (HOLD), you need to hold the keys as it touch the bottom, and release it after it goes off. You can hold the keys as long as you wish in HOLD notes.
Theoretically, the FPS of these calculators can be very high, but the LCD display has a great latency when a pixel blinks, which results in a bad experience. Also, it needs accurate timing (Retrieve time from OS function by magic address is hard to understand) so the FPS in this game is 40 (25 millisecond each frame).
I do not know how to create a chart by myself and have never involved in any development of rhythm game, so there is a Python script for you to turn the Malody chart into the format that fx4K can read.
