Issue: embedded rules language not updated when language is set (in Analyse, Game and Problems)
Also: if new live game starts in background, "new game" notify OK but not first move (not too serious however)
On smartphone for Teleport, Chakart, Weiqi and some others: option "confirm moves on touch screen"
(=> comme pour corr) + option "confirm moves in corr games"?

Squatter Chess: safe on last rank = win
Companion Chess : pieces of same nature don't attack each others
Medusa Chess = Isardam
Crossing Chess = win when the king cross half-board
Kingmaker: pawns can promote also into enemy king
Eightkings: 8 pawns + 8 kings (non-royal until the last remains?)
Crown Chess: place all units on move 1 (similar to Sittuyin, more freely)
