Casio FX-991ES Plus Games Code Repack: A Comprehensive
While the Casio fx-991ES PLUS is a non-programmable scientific calculator, users often "repack" its standard functions to create interactive games and animations using its visual display features. Popular Manual "Game" Repacks
Because you cannot install external software, these games rely on using buttons as visual elements or utilizing random number generators. Tic-Tac-Toe (X's and O's): Setup: Create a
grid by pressing the Fraction button twice to stack boxes, then use the ABS button to fill each cell with a container.
Gameplay: Navigate to a specific box using the D-pad and input "X" (using ALPHA + ) or X) or "O" (using the number 0). Connect 4:
Setup: Press the fraction button and type seven zeros, repeating until you have a
Gameplay: Players replace a '0' with an 'X' (Player 1) or a '÷' symbol (Player 2). Rock, Paper, Scissors: Code: i~Rand(1,3)
Rules: Assign 1 to Rock, 2 to Paper, and 3 to Scissors. Pressing = generates a random play. Guess the Number: Code: Ran# × 10 + 1 Increased game compatibility : By repacking game codes,
Rules: Use this to generate a target number between 1 and 10 for a friend to guess. Display Animations (Visual Codes)
These strings are typed out to create moving "graphics" when scrolling or using the calculator's memory. Volleyball/Tennis: 20118:50118:81018:81102:81105:81018. Cars: 2525252525:5252525252. Pi Attack: Type as many digits of as possible from memory to "high score" against friends. Diagnostic "Games"
You can access a secret diagnostic menu to play a "button test" game: Press SHIFT + 7 + ON at the same time. Press 9 until the screen goes dark. Press SHIFT multiple times to cycle through test screens.
The final stage is a button test: you must press every key in a specific order to "clear" the level.
Note on "Free Fire" or "Snake": Some online tutorials claim you can play high-graphics games like Free Fire by entering long math strings. These are typically community-made "repacks" that simulate a character moving using simple cursors, rather than actual video games.
Because the calculator’s CPU interprets certain constant values as control codes, researchers have mapped:
| Hex value | Effect |
|-----------|--------|
| 0x01 | NOP (skip next) |
| 0x03 | Jump relative +12 bytes |
| 0x8F | LCD refresh (partial) |
| 0x7C | Copy from VctA to display row |
These are not official instructions but side effects of the ROM’s expression evaluator.
The Casio fx-991ES Plus is a non-programmable scientific calculator widely used in education. Despite lacking an official application interface, enthusiasts have discovered that its vector, matrix, and constant memory modes can be exploited to execute pseudo-assembly routines, enabling simple games (e.g., Mario, Snake, Pong). This paper details the forensic recovery, disassembly, modification, and repacking of such game code into distributable keystroke sequences.
