Legend of Kage
(C)1985 Taito
CPU: Z80 (x2), MC68705
Sound: YM2203 (x2)
Phil Stroffolino

Stephh's notes (based on the games Z80 code and some tests) :
1) 'lkage'
- There is an ingame bug about the way difficulty is handled : if you look at code
at 0xa05a, you'll notice that DSW3 bit 3 is tested as well as DSW3 bit 4.
But DSW3 bit 4 also determines if coinage info shall be displayed (code at 0x1295) !
In fact, DSW3 bit 4 is tested only when DSW3 bit 3 is ON ("Normal" difficulty),
so you have 3 different "levels" of difficulty :
bit 3 bit 4 Difficulty
OFF OFF Easy
OFF ON Easy
ON OFF Normal
ON ON Hard
Flame length/color (and perhaps some other stuff) is also affected by DSW3 bit 3.
- DSW3 bit 7 is supposed to determine how many coin slots there are (again, check
the coingae display routine and code at 0x1295), but if you look at coinage insertion
routines (0x091b for COIN1 and 0x0991 for COIN2), you'll notice that DSW3 bit 7
is NOT tested !
2) 'lkageo'
- Bugs are the same as in 'lkage'. Some routines addresses vary though :
* difficulty : 0x9f50
* coinage display : 0x128f
- This set does more tests/things when TILT is pressed before jumping to 0x0000
(see numerous instructions/calls at 0x0318 - most of them related to MCU).
3) 'lkageb*'
- The difficulty bug is fixed : see code at 0x9e42 which reads DSW3 bits 2 and 3.
So you have 4 different "levels" of difficulty :
bit 2 bit 3 Difficulty
OFF OFF Easy
OFF ON Normal
ON OFF Hard
ON ON Hardest
However DSW3 bit 3 isn't tested anywhere else, so flame length/color is constant.
- The coin slots bug is not fixed as coinage insertion routines are unchanged
(coinage display routine is now at 0x13f6).
- These bootlegs are based on 'lkageo' (call to 0x0318 when TILT is pressed).
- Hi-scores, scores, and as a consequence bonus lives, have been divided by 10,
but it's only a cosmetical effect as data from 0xe200 to 0xe22f is unchanged.
4) 'bygone'
- is it prototype ?
- MCU (same code as lkage) is not used
- No music ? (could be emulation bug) (the 2nd YM is not used...)
TODO:
- 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
(because there is no test at 0x033b after call at routine at 0xde1d).

Taito, 1985?
This is a rare prototype platform game conversion on a Legend Of Kage PCB.
There are some wire mods on the video board.
