- The keyboard leds I'm turning on are actually the gun solenoid outputs, which

would rattle the gun while firing.

- BM, 060108 - The original flyer for this game has screenshots which clearly
|

show the background is 4 pixels to the left on several game stages (you can
|
||||
see the edge of sprites overlapping past the right edge). Therefore I
|

do not believe the TC0100SCN problem mentioned above actually exists. The

current emulation appears to be accurate.

Stephh's notes (based on the game M68000 code and some tests) :

- Schematics show a OBPRI output to control sprite priority. This doesn't seem
|
||||
to be used however, and isn't hooked up. See othunder_TC0220IOC_w().
|
||||
|
||||
- TC0100SCN problem: text vs. bg0/1 offsets are wrong: first level
|
||||
wants bg0 4 further right. Cut screens (all?) want bg0 4 pixels
|
||||
further left. But the bg0 x scroll value is zero in both cases!
|
||||
(and the code setting it is a CLR, so there's no doubt it's meant
|
||||
to be).
|
||||
There are no set bits in the TC0100SCN ctrl regs which might be
|
||||
causing this. So I'm mystified. (Maybe it's related to game being
|
||||
ORIENTATION_FLIP_X ??)
