HP Prime Emulator
Jean-Baptiste Boric:
Here's the PRIME_OS.ROM of Rip'Em and the ELF programs, for testing on your side.

Thank you very much. I'll try to get it running in qemu now
Just a little update. Got ripem to run! No functionality yet as GPIO is not implemented yet but it's giving me correct graphical ouput. ;D ;D ;D
Edit (Eeems): Merged double post
Jean-Baptiste Boric:
So I took a quick look at your branch and I've already submitted a pull request (mostly just cleanups to make it work on my Linux box).
Soon I'll finally be able to work on Rip'Em without losing my sanity in the process. Yay! :w00t:
gigi1237:
Great changes, nice idea of using the exynos uart. It appears to be similar (identical?).
But I'm still stuck as to why the original prime_rom won't boot. I'm really at a loss. :banghead:
Jean-Baptiste Boric:
Rip'Em is a really, really simple piece of code, so it's fairly easy to make it run. It doesn't even uses interrupts or timers, it has effectively the equivalent complexity of a "Hello World!"-class program.
The official firmware is infinitely more sophisticated than that. There's much, much more going on inside a HP Prime than just a ARM9 core and a bunch of RAM.
