UCI2WB relelease notes
UCI2WB is an adapter for running USI (Shogi) engines under WinBoard.
Install USI2WB in WinBoard as if it was the engine, with one or two arguments
on its command line, to indicate the name of the real engine executable,
and (optionally) its working directory.
E.g. when you have placed USI2WB.exe in a sub-folder 'Adapters' inside the WinBoard folder,
you could include the following line in winboard.ini amongst the firstChessPrograms:
"UCI2WB -s USI_ENGINE.exe ENGINE_FOLDER" /fd="./Adapters" /variant=shogi
UCI2WB was developed with gcc under Cygwin. It can also be used as a (dumb) UCI2WB adapter.
"Dumb" here means that the adapter does not know anything about the game state,
and just passes on the moves and position FENs as it receives them from engine or GUI.
As this can be done without any knowledge of the game rules, or even of the board size,
such a dumb adapter can in principle be used for any variant. To use it for UCI protocol
(both the Chess or Xiangqi dialects), use it without the -s flag (or with a -c flag).
As of version 2.0 UCI2WB also supports the UCCI protocol for Xiangqi, for which it was
made slightly less dumb: in UCCI mode it keeps track of the board position on a (Xiangqi)
board, so it can recognize capture moves, and send only the moves after it (with an
appropriate FEN to start them from).
The general syntax of the UCI2WB command is:
UCI2WB [debug] [-var VARIANTLIST] [-s|-c|-x] ENGINE.exe [ENGINEFOLDER]
Presence of the 'debug' argument causes UCI2WB to report everything it receives from the engine,
as well as the 'position' and 'go' commands sent to it, as debug output (prefixed with '#')
to the GUI. This has the same effect as switching the option 'UCI2WB debug output' on,
except that it forces the option to be on from the very beginning, so that the engine
startup will also be reported.
The '-var' option overrules the list of variants UCI2WB says it supports with the given list,
like 'feature variants="VARIANTLIST"'.
This package includes the source code. To compile on Windows under Cygwin, use the commands
windres --use-temp-file -O coff UCI2WB.rc -o rosetta.o
gcc -O2 -s -mno-cygwin UCI2WB.c rosetta.o -o UCI2WB.exe
To compile under Linux, use
gcc -O2 -s UCI2WB.c -lpthread -o UCI2WB
Have fun,

Made sending of debug info to GUI subject to option feature / command-line argument.
Fixed myname feature to handle names containing spaces.
14/10/2010
Port v1.5 to Linux
26/9/2010 v1.5
Add mini-Shogi ("variant 5x5+5_shogi") in USI mode; make coordinate translation board-size dependent.

??/?/2010 v1.3
Add work-around for non-compliant USI engines that do not understand winc, binc, movestogo.

as some engines use this score when they reach repeats they would win if continued.

Corrrect thinking time to centi-sec
17/7/2010 v0.4:
Introduced compiler switch that enables some macros for everything that is different
in USI compared to UCI.
Fixed pondering.
Fixed setboard (for UCI).
Added result claims on checkmate / stalemate (for engines that say 'bestmove (none)').
16/7/2010 v0.3:
This is the first version for which the basics seem to work.
It could play a game of Blunder against itself, ending in resign.
Options of all types should work now.
Only classical time control tested.
Pondering not tested. (Blunder does not give a ponder move?)
Setboard not tested. (Probably does not work due to FEN format discrepancy.)
No analyze mode yet.
No SMP yet.
