Project Window, Emulator Data Tab
The EMU48 emulator requires a memory image of the RAM. These files are called *.e48 or *.e49. The user can have as many of these files as desired. Sometimes a user prefers the same e48 or e49 file be used for all projects. Sometimes, the user might want a special e48 or e49 file for experimentation or another file for a special project etc. When a new project is created, Debug4x will enter a default name into these boxes. The name can be changed to reflect the needs of the user.
The type of emulated calculator (HP48 or HP49) is solely determined by the contents of these files. Unless you are very familiar with the EMU48 emulator, it would be better to copy the default files supplied with Debug4x and then tailor the files for a particular use.
Browse: this button opens a dialog box for selecting the proper e48 or e49 file.
Emu48 Port2 File
This file is used to emulate the Port 2 RAM card of the calculator.
Since installed libraries from port 2 may be "attached" to the directories (like
HOME) of the calculator .e48 RAM file, these files should be in pairs.
Always use the matching .bin file for the .e48 file.
If this is not done, EMU48 will use a default file (set in the registry when running from Debug4x or set from a C:\Windows\Emu48.ini file when run from the start menu). When the .bin file does not match, the calculator will do a warmstart or blink when first started or when keys are pressed.
The HP-49 emulator uses a FlashRam emulation and does not use the Port2 files.
There is a lot more on Port Memory.
