I just add a small program to illustrate the type cast between signed
and unsigned:
var
si: ShortInt;
begin
si:= -127;
WriteLn( 'si ', si);
WriteLn( 'Byte(si) ', Byte(si));
si:= -1;
WriteLn( 'si ', si);
WriteLn( 'Byte(si) ', Byte(si));
end.

Indeed.
This is a lossless operation.

I got the list of functions you mentioned in Lazarus.. Here are all the ones
that can read:

You'll have to use the Integer / Int64 variant and hardcats it to DWord/QWord.
IIRC this is Delphi compatible.
Of course it is peanuts to implement Read/WriteD/QWord() yo
I'm not using Lazarus.
I guess I can try to make a sample program with it just to see what the
options are.
It seems like there should be a ReadDword, and ReadQword because there are
an awful lot of Dword and Qword types in the registry.

In Lazarus , in your source code, you can can "Ctrl + Click" on
Registry.ReadString and it will bring you to the declaration of
TRegistry.ReadString in unit Registry. There you will find there are
other methods like ReadInteger, ReadInt64, ReadBinaryData. I'm not sure
which one will best match
Is there documentation for TRegistry somewhere? I've been searching for
information on it, and so far I've only been able to find:
https://wiki.freepascal.org/fcl-registry
and

They kind of get me started but
