Top Board:

|

Video hardware consists of scaling sprites with a Mode 7-style ground?
|

TMS34010 seems to draws text, score etc.

(MSM6295 + Crystal) * 4
|

|

It looks like a bistream for a Xilinx FPGA is stored in ROM. The sub
|
||||
CPU bit-bangs 30864 bits worth of data to 0x40000003 twice.

68EC030-40
|
||||
TMS34010-50
|
||||
|
||||
Video hardware:
|
||||
|
||||
- Blitter that supports rotation and zoom (background and sprites)
|
||||
- TMS34010 (text, score)
|
||||
|
||||
Notes:
|
||||
|
||||
- It looks like a bistream for a Xilinx FPGA is stored in ROM.
|
||||
The sub CPU bit-bangs 30864 bits worth of data to 0x40000003 twice.
|
||||
|
||||
- There seems to be a bug in the game code drawing routines, causing objects to have some pixels
|
||||
chopped off. This is most noticeable for distant thin objects (falgs, poles of the start banner).
|
||||
See maincpu routine at 387B8, specifically the jump at 3880E throws 4 horizontal pixels away.
|
||||
|
||||
- The player often disappears (when she's too slow?). Is this normal ?
|
||||
|
||||
- Are button 2 and analog input "Y" used ?
