Weak rumble in numerous titles

[mackieks]

Description:
Some games exhibit weak/faint rumble during gameplay. None seem to be WinCE games.

• Maybe a bug in the vibeHandler function? (unlikely)
• Or these games use continuous vibration, and the incomplete implementation is only generating one pulse and ending, instead of repeating the pulse until AST is hit (more likely)

To-do:
Capture logic traces with HKT-7700+Performance TremorPak and MaplePad to compare behavior.

Affected titles:
(tested on 1.4b)

• Fighting Vipers 2
• Looney Tunes Space Race
• Macross
• Marvel vs Capcom
• Mr. Driller
• Powerstone 2
• Sega Marine Fishing
• Soul Calibur
