＝ (Yes) before attempting a repack code to ensure the RAM configuration is clean.

To prevent yourself from guessing the same number every time, you need to randomize the calculator’s internal seed. Type a random decimal or whole number into the screen.

ROP is a more advanced technique. Instead of directly writing machine code, an ROP attack strings together small snippets of existing code (called "gadgets") that already exist in the calculator's firmware. By chaining these gadgets together, you can achieve more complex results, such as dumping the calculator's entire ROM (Read-Only Memory) for analysis.
