MAME Info:

0.104u9 [David Haywood]


* Dump Harddisk and YMZ280B sound rom


- 0.145u7: Improvements to Jaleco's "Stepping Stage Special" [Luca Elia]: Fixed memory maps, rom loading and added inputs. Hooked up sprites, hacked in the text layer. Can be made to boot using the debugger. Added YMZ280B (16934400 Hz) sound. Mirrored sprites_horiz rom to foreground. Changed visible area of the 3x screens to 352x240.

- 25th September 2011: Luca Elia - Jaleco's Stepping Stage Special getting to the title screen by manually poking the right values in memory during boot. This is a 3-screen dancing game with a full blown Windows PC as slave to play music, and tetrisp2.c derived hardware for graphics. Palette RAMs do not make much sense at the moment, so excuse the gaudy colors.

- 0.143u2: Made some basic progress to Stepping Stage driver [Angelo Salese]. Added 8-way Joystick for 2x players with 3 buttons. Changed 2nd screen visible area to 320x224. Added dipswitches 'Coin A/B', 'Free Play', 'Service Mode', 'Difficulty', 'Vs Mode Rounds', 'Language', 'F.B.I Logo', 'Voice', 'Demo Sounds' and 'Flip Screen'.

- 0.134u4: Naibo Zhang changed 'Stepping Stage' description to 'Stepping Stage Special'.

- 0.131: Aaron Giles merged memory maps in Stepping Stage.

- 0.129u2: Naibo Zhang added also custom 3-screen layout to Stepping Stage driver.

- 0.104u9: David Haywood added Stepping Stage (Jaleco 1999).

- 18th February 2005: A EPROM downgrade kit from one of Jaleco's music games arrived from Japan.
