Installing emu48 on HP 50g question and others

[psun9999]

Hi there,

Should anyone have any suggestions on the following three issues, I would
appreciate it.

1. I am just being reacquainted with my HP 50g which I haven't used for a few years.
I am trying to install emu48 for the HP 50g on my Windows 10 laptop.
I downloaded the hp50gsemu48.zip file from Hpcalc.org website and I extracted
the files into a separate folder. When I ran the emu48.exe file, I get the following
error message from the installer:

"This KML Script doesn't specify the ROM to use, or the ROM could not be loaded."

The subfolder ROM and the two roms are there. Any suggestions on why I get this error
message?

2. I am trying to remove the 1216 battery from my HP 48SX 128 KB memory card
but I cannot remove the battery holder from the card. Any suggestions on how
to do this?

3. When I reviewed some the manuals and books about the HP 48 calculator,
the books use a dot matrix font to display the programs discussed. Is there any
place on the web that I can download similar font to use with Windows 10 that
is compatible with the emu48?[/size][/font]
