Rewrote sbrkout driver based on schematics:
* XTAL-based timing
* Correct video timing
* Full memory map
* Correct memory usage ("zero page" RAM is shared with videoram)
* Removed all input hacks
* Fixed interrupt generation
* Connected coin counters
* Added save state support
Also fixed incorrect dependency in cdrom.c.

Note: I'm cheating a little bit with the paddle control. The original
|
||||
game handles the paddle control as following. The paddle is a potentiometer.
|
||||
Every VBlank signal triggers the start of a voltage ramp. Whenever the
|
||||
ramp has the same value as the potentiometer, an NMI is generated. In the
|
||||
NMI code, the current scanline value is used to calculate the value to
|
||||
put into location $1F in memory. I cheat in this driver by just putting
|
||||
the paddle value directly into $1F, which has the same net result.
|
||||
To do:

* Merge with Sprint 1
|
||||
|

If you have any questions about how this driver works, don't hesitate to
|
||||
ask. - Mike Balfour (mab22@po.cwru.edu)

MAB 05 MAR 99 - changed overlay support to use artwork functions

Stephh's notes (based on the games M6502 code and some tests) :
|
||||
|
||||
- Each time the game is reset, it is set to "Cavity".
|
||||
I can't remember if it's the correct behaviour or not,
|
||||
but the VBLANK interruption is not called in "demo mode".
|
||||
- You can only select the game after 1st coin is inserted
|
||||
and before you press BUTTON1 to launch the first ball,
|
||||
then the VBLANK interruption is no more called.
|
||||
This means that player 2 plays the same game as player 1.
