Space Stranger hardware info by Guru
This is a black/white Space Invaders clone made by Yachiyo Electric Co. Ltd. using colored cellophane
to make it look colored. This is probably the same game known as Super Space Stranger on the flyer
and also has 'Super Space Stranger' printed on the control panel/marquee.
Super Space Stranger is said to be made by Ban Presto but the hardware is identical to the Yachiyo PCB.
Additionally there is no evidence in the game or on the control panel or marquee or PCB to suggest it
was actually made by them, so this info is probably false or guessed, or perhaps Ban Presto just
distributed it. Either way there is no evidence that Ban Presto manufactured it.
to make it look colored. The gameplay is mostly the same as any other Space Invaders game except the mother
ship changes direction randomly and if the player hits the shields 50 points are deducted from the score.
So be careful, score can go to 0 very quickly!
The sounds are very close to Taito Space Invaders, possibly even identical.
The hardware has a built-in service mode with RAM/ROM test and I/O check.
When enabling the I/O check, if ROMs or RAM are bad various sounds are made to denote the bad chips.
The following table summarizes the chip locations and sounds made. Note a bad CPU will also cause sounds
to be made on bootup but the I/O check or other in-game tests will not be available.
Chip# Type Sounds Made
------------------------------------------------------
38 4116 RAM UFO Flying then Extra Ship
39 4116 RAM Player Shoot then Extra Ship
40 4116 RAM Player Explosion then Extra Ship
41 4116 RAM Invader Explosion then Extra Ship
51 4116 RAM UFO Flying then silence
52 4116 RAM Player Shoot then silence
53 4116 RAM Player Explosion then silence
54 4116 RAM Invader Explosion then silence
58 EPROM 01 Player Shoot then Invader Explosion \
59 EPROM 02 UFO Flying then Invader Explosion |
60 EPROM 03 Invader Explosion |
61 EPROM 04 Player Explosion then Invader Explosion |
62 EPROM 05 Player Shoot then Player Explosion | also with Invader movement sounds
63 EPROM 06 Player Explosion then UFO Flying |
64 EPROM 07 Player Explosion |
65 EPROM 08 Player Shoot then UFO Flying /
These are schematics available for Space Stranger but the scans are too small to read so completely useless.
There is another game known as 'Super Space Stranger' that has a service manual available with schematics.
It is also known as 'Mark Stranger 2' and is a color version of the same game.
There is a Super Space Stranger flyer that shows the game as b/w with color bars. The game has 'Super Space Stranger'
printed on the control panel of the b/w cocktail cabinet but the manual also just says 'Space Stranger' in many places,
so there is some uncertainty about exactly what the color version is called. The title screen of the color version just
says 'Space Stranger'. Super Space Stranger is said to be made by Banpresto but that is false because Banpresto didn't
exist until 1989. Additionally there is no evidence in the game or on the control panel or marquee or PCB stating any
other manufacturer other than Yachiyo.
It gets more complicated... the Super Space Stranger service manual has text at the bottom of each page 'HOEI SANGYO CORPORATION'
At the time Hoei (founded in 1977) was doing arcade-related work for Sega but there is no evidence to suggest the
PCB was manufactured by Hoei. It is possible Hoei made the PCB for Yachiyo since they were also doing arcade work
for Sega, although exactly what work (hardware or software) is unknown. Hoei changed their name to Coreland in 1982
and later in 1989 they became Banpresto.

Notes:
The long slots are KEL 4800-100-035 100 pin female card edge connectors with 0.156" pin spacing.
On the diagram above * denotes pin 1 of the 14 pin connectors.
Space Stranger uses this board to join the top and bottom boards together and provides a way to wire up the
controls/video/power etc to the machine via the left and right 14-way edge connectors.
The game has a table/upright mode that can be changed by connecting two jumper pads on the joiner PCB with a solder blob.
This is located at pin 40 on the top board and is conveniently made available on the back side of the joiner board
with the two solder pads. When open it sets table mode, when closed it sets upright mode.

Note: NC means No Connection.
To access the I/O Check Mode, ground R17 (side near edge connector) on the top board or ground pin E
of the left edge connector then power up the game.
The I/O test screen shows 3x 8-bit memory locations with bits that change when controls and settings
are adjusted. Note if sounds are heard, check the RAM/ROM test table above.
For the purpose of describing each bit, they will be called Byte A, B & C.
With all DIP switches off and controls at default positions, the 8-bit memory locations look like
this in the default state:
1 1 1 1 1 0 0 0 <-- Byte A
0 0 0 1 0 0 0 0 <-- Byte B
% 0 1 1 1 1 1 1 <-- Byte C
0 means open, 1 means closed. & denotes moving fast between 0 and 1
Refer to the table below for the meaning of each bit.
Bits described on each line are the position(s) denoted by the X and
as read from the screen left to right.
Byte A
------
X X X X X - - - : Dip Switches 1-5. 1 when DSW is off, 0 when DSW is on
- - - - - X - - : Fire Player 2 (Note when pressed, the characters on screen are flipped vertically. This is normal)
- - - - - - X - : Left Player 2
- - - - - - - X : Right Player 2
Byte B
------
X - - - - - - - : Coin
- X - - - - - - : 2 Player Start
- - X - - - - - : 1 Player Start
- - - X - - - - : I/O Check (always 1 when in the I/O check mode)
- - - - X - - - : Table/Upright setting. 0 for table, 1 for upright
- - - - - X - - : Fire Player 1
- - - - - - X - : Left Player 1
- - - - - - - X : Right Player 1
Byte C
------
X - - - - - - - : Interrupt. This is always rapidly moving between 0 and 1
- X - - - - - - : Rapid Fire (only used on color version)
- - X X X X X X : Always 1
Color version Space Stranger 2 / Mark Stranger 2 etc
----------------------------------------------------
As well as a different PCB number (YD-7700), the color version PCB has one 64kbit mask ROM and one 2708 EPROM
for the code and an extra 2708 EPROM near the 10MHz crystal for color data and a few extra logic chips, so it
is easy to spot the color version just by looking at the bottom PCB. The top board is identical to the older
b/w version Space Stranger top board and sounds are also identical between versions.

TODO:
* Using sound samples from Space Invaders (real PCB sounds virtually identical anwyay). Get schematics and use netlist instead.
* Fix attract mode and I/O test random sound (should be silent)
* Screen should flash red when losing a life in Space Stranger 2 (see video reference)
