Friends who like playing mahjong should be happy now.

Dip Switch settings ( TAB ):
Difficulty: difficulty ( 0 - 3 )
Coin A: coin ratio A ( that is, pressing 5 once counts as 1, 2, 5, or 10 points )
Min pay: minimum points needed to start ( 1, 2, 3, 5 points )
Allow Coin Out: whether coin-out is allowed ( that is, cashing out points, default On )
Win A Prize: stage-clear reward (whether the voltage rises after three dealer streaks)
Pay Out Rate: coin return rate (of course the higher the better, 50% - 96%, too bad there isn't 100% )
Max Bet: maximum points to bet at one time ( 1, 5, 10, 20 )
Coin B: coin ratio B (that is, pressing 6 once counts as 5 or 10 points, 5 - 7 points)
Flip Screen: adjust screen display direction
Service Mode: On / Off setting ( default is Off )
YAKUMAN Bonus: whether there is a yakuman chance ( very important, otherwise you may never win a yakuman, default is Cut - none, the others are 1 for only 1 time, 300, 500, 700, 1000, meaning one will appear only after putting in that many coins; recommended setting is 300 )
YAkU Times: how many hands are given each time a yakuman appears ( 1 hand or 2 hands, 2 is recommended )
Win Rate: winning probability when the voltage rises ( that is, during a three dealer streak, so High is recommended )
Allow Continue: whether continuing with more coins is allowed
Unkown: 129/212 ( actually this should be whether the Donden button exists; 129 should be Off, meaning the default A key, while 212 means On, meaning there is a dedicated tile-swap key; it is recommended to leave it at the default 129, otherwise you can't swap tiles )
Subtitle: base board version (Part2 or Part3 Express version; Part3 has prompts for chi/peng/kong/hu, and randomly shows blind tiles, that is, previewing the next 5 tiles you will draw )
Last Chance: haidi On/Off ( if set to Off, then before haidi it will ask whether you want to spend one coin to buy a haidi chance )
Pay Rate: betting point ratio ( High / Low )
Choose Bonus: whether bloodletting can appear in the dealt hand?
In Game Bet: can you raise the bet during the game?
Demo Sound: demo sound On/Off
In Game Music: game music
Select Girl: whether stage selection is available
Moles On Gals Face: the moles on the game characters' faces ( On / Off )
Allow Bets mode selection ( if set to Off, it becomes a pure odds gambling mode, that is, wins and losses are represented by Rate, and it is not limited by the maximum 20-point bet )
