How to create a ROM image for DOS Emu48 v0.37
---------------------------------------------

Download the filetool.zip archive from
http://hp.giesselink.com/Pcuti/FILETOOL.ZIP please.

1) Unzip the FILETOOL.ZIP archive

2) Copy the files ROM.48G and ROM.48S from your Emu48 for Win32
   directory into the directory with the extracted filetool files

3) Newer Emu48 versions can also handle packed ROM images, so you
   have to check if the ROM.48G or the ROM.48S file is already
   packed or not. A packed ROM.48G file has a size of 512KB, a
   packed ROM.48S file has a size of 256KB. Unpacked ones have
   double size.

   If they are already packed use

   rename ROM.48G ROM48G.ROM
   rename ROM.48S ROM48S.ROM

   to rename the files and skip the next step.

4) Create packed ROM files at the command line with

   emu2rom.exe ROM.48G ROM48G.ROM
   emu2rom.exe ROM.48S ROM48S.ROM

5) Create the Dump files at the command line with

   rom2dmp.exe ROM48G.ROM ROM48G.DMP
   rom2dmp.exe ROM48S.ROM ROM48S.DMP

6) There's a bug in the Emu48 dump2rom.com utility which prevents
   converting the HP48SX ROM file. To fix this remove the CR LF
   characters at the end from the ROM48S.DMP file. There are some
   text editors which add automatically a CR LF at end of file,
   such editors cannot be used of course.
   The notepad.exe program from Win2K worked for me.

7) Follow the instructions in the emulator README file how to create the
   final ROM image

   dump2rom.com ROM48G.DMP

   The resulting file is a nibble swapped packed ROM file.
