HP18C/28C Emulator

Emu28 emulating a HP28C Emu28 is an emulator for the Clamshell series calculators HP18C and HP28C. It base on the sources of the famous HP calculator emulator Emu48 and is published under the GPL. The emulator is running on all Win32 platforms. You may have a look onto the latest changes. Like all emulators Emu28 needs a ROM image to work. I have no license to publish them, so they aren't included in the emulator package. Sorry I will not answer any ROM image related questions. For further questions how to check ROM images read the Emu28 manual please. I want to thank Sébastien Carlier, Cyrille de Brebisson and Jean-François Garnier for there material I used for making this program.

Since Emu28 v1.19 of the Win32 version the saving location of the emulator settings changed from the Emu28.ini file to the registry at HKCU\Software\Emu28. So when you update Emu28 from v1.18 and earlier to the latest version you will lose all your settings. The program E28INI2REG.exe is copying these settings automatically to the new location.
