to Walter Montego:

Well Smirf is supporting the basics of PGN. That is that games based on 8x8 standard chess or 10x8 extended capablanca piece set could be saved and loaded. Actually e.g. Janus Chess, Chess, Chess960, Gothic Chess (if enabled by a key) and Capablanca Random Chess could be filed as PGN also enabling comments but not yet additional move variants within a game. Additionally a lot of other chess variants could be supported, if they simply are using a different starting array.

To get an impression of Smirf's abilities you could download a restricted beta version from:
