about.pas missing in Emulator/Emulator.dproj

[darnocian]

If you inspect the dproj:

<DCCReference Include="C:\Program Files\Borland\Delphi5\Objrepos\about.pas">
<Form>AboutBox</Form>
</DCCReference>

I removed about.pas from the .dpr and .dproj file, but I cannot compile since some files are missing.
