0.97u1 [Luca Elia, BNathan]


< Japan >


WIP:

- 0.165: Added gambling control.

- 0.114u1: Changed OKI6295 clock speed to 1022720 Hz.

- 0.98u2: Added 2nd coin slot.

- 0.97u1: Luca Elia added 'Mahjong Reach Ippatsu (Japan)' (Nihon System 1998).

- 29th May 2005: Luca Elia - More post 1996 Dynax games: Hana Kagerou (1997) - another hanafuda (i.e. cards) game and Mahjong Reach Ippatsu (1998). There are no more dumped Dynax games, so I'll tackle the remaining graphics bugs next.

- 22nd May 2005: Luca Elia - I'm working on the post 1996 Dynax games. This hardware is based on a new revision of the blitter chip emulated in DonDenLover driver. The driver is still preliminary, as there are several graphical glitches that need to be ironed out before sumission. For example the background color is wrong in the title screens (those odd white pixels). There are other dumped games running on this platform. I'll add them in the following days, and hopefully they'll give me some hints in the right direction. Many thanks to Yasuhiro Ogawa for providing pictures from the original game!
