I see in this discussion that the source code of the Nero XBoard engine has been available. Would someone know where I could download it ? It's for my collection of Pascal programs. :)

Hi Roland, as it looks you will try this on more programs in the future, I suggest first looking at the XB/UCI chronology,
may be it contains older links which contain what you want.
Ok, in this case it would not have helped, therefor my second suggestion, if above fails, go to the WB forum and do
a little search for the concerning program and you'll most likely find an old link, if this link doesn't work, just open the
great Wayback archives (https://web.archive.org) and insert the old link there :)
(Sites of chess programs often were archived by request of chess afficionados and programmers)
In one minute I had found this: On page 2 you'll see results for the Nero source of three versions (unnamed, 5.1 and 5.3 - no trace for 6.x yet)
if ((forwhite) and (bestvalue>=beta[depth-1])) then cutoff:=true;
if ((not forwhite) and (bestvalue<=beta[depth-1])) then cutoff:=true;
if ((forwhite) and (bestvalue>9000)) then cutoff:=true;
if ((not forwhite) and (bestvalue<-9000)) then cutoff:=true;
The programs compiles and runs on Linux, but I failed to get it to work, neither in CuteChess nor in XBoard. If I have the time I'll try to see what's wrong.
If someone had the source of the version 6, that would be good.
It's a Lazarus compile of Nero 6.0, including source. I don't know if Dann modified it in any way to get it to compile with Lazarus. Sorry, I don't have the source for version 6.1, unless it's hidden in a folder on one of my numerous old drives.

I have not been able to get the supplied compile to work for me. I tried several GUIs, and even wb2uci, and no luck. I noticed it was a 64 bit executable. Perhaps Dann was trying some modifications. I saw a link to an old thread on the Chess Programming Wiki's entry for Nero.
I have just tried. It doesn't solve the problem. But anyway it's certainly a good idea to use it.
Meanwhile I also found out with the help of the WB forum again, that Jari had changed his website since Nero version 6.
The 'new' address was saved once in Wayback, but just delivers an empty page.
So sources newer than 5.3 can only be found in private collections anymore.
