Add support for EMA ruleset #33

Closed EmeraldCoder closed 2 years ago

EmeraldCoder commented 2 years ago

EMA is the European Mahjong Association and its ruleset differs from the WRC ruleset that we use by default in the application.

The application already supports the concept of different rulesets. Supporting the WRC and custom rulesets.

Would need to analyze the EMA ruleset, list their rules, and ensure that the options that we have already implemented are sufficient to support the ruleset.

Here a few details that I found about how we can configure the ruleset with our current options:

Kazoe yakuman value = sanbaiman
Allow multiple/double yakuman = no
Allow open tanyao (kuitan) = yes
Allow double wind fu (when the seat and the round is the same wind) = yes
Renhou value = mangan
Round up to mangan (kiriage mangan) = no
Allow open riichi = no

Seems like there is no special cases that would need to create more configuration option.
