I confirmed the game freezes randomly.
In my case, the game stopped when I tried to draw cards, then I reset the game and tried to draw cards with the 1 key, it freezes again.

(Haze) > if you look in WRITE8_MEMBER(igspoker_state::custom_io_w)
there is a basic protection simulation (which could really just be returning data from a fixed table, the first returns are the letters IGS, which is not uncommon) maybe some values are missing for those games.

Above Haze gave the hint of where the problem is and actually although they are similar the games in this series are not the same and do not use the same table, so the freezing occurs. You must map the correct values ​​and implement the tables correctly for these games. At the moment they should be labeled "No working".
