Information on itazuram

0.141u2 [Luca Elia, Gnoppi, john666, Gerald (COY), Smitdogg, The Dumping Union]


- The first time you run the game, an ERROR appears. Hold down F2 + F3 for about 4 seconds to enter TEST MODE. Select 'SET MODE' with F2, enter with CTRL, then use F2 to select 'RAM CLEAR'. Hold down CTRL until 'OK' and press F3 to proceed.


- 0.141u3: Changed Z80 CPU1 clock speed to 10MHz, added OKI9810 (4096000 Hz) sound and 2MB OKI rom.

- 0.141u2: Luca Elia, Gnoppi, john666, Gerald (COY), Smitdogg and The Dumping Union added Itazura Monkey (Sammy 2000).

- 7th February 2011: Luca Elia - The Dumping Union got the chance to acquire an obscure Japanese system by Sammy. It's a cartridge based platform for some cute medal games for kids. The gameplay is very simple: just one big flashing button to push at the right moment to try and catch some funny animals. The two working games at the moment are Animal Catch and Itazura Monkey. Each cartridge contains two flash roms (code+samples and graphics). The main board has not been found yet, but I figured out that the hardware is a variation of the one running GeGeGe no Kitarou. I wrote a driver for that a few months back, and it's based on a graphics chip by Taxan (256 color sprites with zooming). There are three more carts dumped, but each one requires its own ROM/RAM banking scheme and memory map (just to prevent the operators from reflashing an old cart with new games), so they do not work yet. Also, the sound chip is unemulated. Anyone fancy writing a sound core for the OKI MSM9810 sample player? It would help Funcube also. Thanks to Gnoppi, john666, Gerald (COY), Smitdogg and The Dumping Union.

- 30th January 2011: Smitdogg - I dumped some Sammy carts we got, they go to an old medal system called Treasure Fall. Luca is trying to emulate them. They are called Animal Catch, Itazura Monkey, Taihou de Doboon, Pye-nage Taikai and Hae Hae Ka Ka Ka.

- 25th December 2010: Smitdogg - I found some rare Sammy carts. They go to an old medal system. Nothing is known about the system hardware so if you know anything, let us know. Titles from left to right are Itazura Monkey ("mischievous monkey"), Animal Catch and Pie Nage Taikai ("pie-throwing tournament").
