Run Doom on your PrimeG1 - NatsukiMin - 2026-03-14 04:02 All of the following is based on the HP Prime G1 running firmware version 2025-09-15. 1. Restart the Prime to free up enough RAM for uploading files (Why does the Prime need to upload files to RAM first? And why does it upload files without splitting them into chunks?)  2. Upload BackdoorInstaller and DOOM to your Prime.  3. Run BackdoorInstaller.  4. Run DOOM.  The reason all of this—including running binaries—is possible is because of the Prime's "open" OS.  Since it's glitchy, it's easy to find a way out.  So, if any official engineers are seeing this, could you please fix the null pointer access issues and use tools to analyze the memory leak? We urgently need a more stable machine.  Or at the very least, please avoid aggressively rebooting on every illegal write—this could seriously damage the fragile YAFFS FTL and cause a C: drive nuke. Most illegal writes are caused by calculator software, not the OS itself.  BTW, the new system’s PPL is extremely slow, so I’m having a much worse experience playing old games in PPL.  **Advertisement:**  Primeshim is a project aiming to port HP Prime’s calculation software to Linux. If future OS versions are still buggy, we can switch to Linux + shim mode to avoid software crashes leading to system crashes.  https://github.com/Natsuki-Min/PrimeShim/tree/main/PrimeReal
