/***************************************************************************
Zero Hour / Red Clash
runs on hardware similar to Lady Bug
initial driver by inkling
Notes:
- In the Tehkan set (redclashta) the ship doesn't move during attract mode.
Earlier version? Gameplay is different too.
TODO:
- redclash supports more background layer effects: white+mixed with other colors
scrolling at the same speed as the stars, it's used in canyon parts and during the
big ufo explosion
- redclash canyon level, a gap sometimes appears on the right side, maybe BTANB
- replace samples with netlist audio (schematics available for zerohour)
- zerohour should play a beep when an orange asteroid is shot (not sure if it's
worth simulating this, netlist would auto solve this problem)
- does redclash have more triggered sounds? according to a pcb video, it only
has the player shot sound, no explosions (not counting the beeper)
- redclash beeper frequency range should be higher, but it can't be solved with a
simple multiply calculation. Besides, anything more than right now and ears will
be destroyed, so maybe the sound is softer(filtered)
BTANB:
- redclash gameplay tempo is erratic (many slowdowns)
- redclash beeper sound stops abruptly at the canyon parts
- other than the pitch being inaccurate (see TODO), redclash beeper really does
sound like garbage, the only time it sounds pleasing is during the boss fight

// c4 was more damaged (lots of bytes replaced with 0x00) possibly UV exposed.
// I'm not sure where this rom is used by the game (wp 2000,800,r and bp 2000,800 catch nothing) for now I'm assuming it was meant to match.
// the game seems to be based off the 'zerohour' set but like many Inder sets it has some code inserted at the end of the last rom that is called by the game (bp 2fe0)
// Inder boards with the regular Universal code have also been seen.
