0.35RC1 [Phil Stroffolino]


- The high score display uses a video attribute flag whose pupose isn't known.

- Purpose of the 0x200 byte prom, "a54-10.2" is unknown. It contains values in range 0x0..0xf.

- SOUND: lots of unknown writes to the YM2203 I/O ports.

- Note that all the bootlegs are derived from a different version of the original which hasn't been found yet.

- lkage is verfied to be an original set, but it seems to work regardless of what the mcu does. Moreover, the mcu returns a checksum which is different from what is expected - the MCU computes 0x89, but the main CPU expects 0x5d. The game works anyway, it never gives the usual Taito "BAD HW" message.


- Sound section is almost identical to Bubble Bobble, YM2203 instead of YM3526.

- There are actually 1024 colors in paletteram, however, we use a 100% correct reduced "virtual palette" to achieve some optimizations in the video driver.

- Clone lkageb probably uses another MCU dump, which is undumped. MAME use a fake MCU for it.


- 17th July 2000: Nicola Salmoria added correct MCU communication to Legend of Kage.

- 0.35b5: Added lkage.c driver.

- 19th June 1999: Phil Stroffolino sent in a Legend of Kage driver with a fix to the text layer color.
