Commercial HP65 emulator for android.
Packs works similar to go67c.
Here you can find the Standard pack.
Cards are saved as ascii files (whole 618 bits circular register saved as 103 words of 6 bits (in octal))
Emulator loosely based on Non-Pareil from Eric Smith.
Thanks to Jacques Laporte for its hp 65 java emulator (used to check my emulator).
