Puzzle Bobble

Some Power Spikes II MVS cartridges were converted to Puzzle Bobble by SNK by doing the following:
 * Replaced the Power Spikes II P1 ROM by the Puzzle Bobble "d96-07" P1 ROM in the EP1 spot.
 * Replaced the Power Spikes II V3 ROM by the Puzzle Bobble "d96-01" V3 ROM, also added the "d96-05" V4 ROM.
 * Replaced the Power Spikes II C5 and C6 ROMs by the Puzzle Bobble "d96-02" C5 ROM and "d96-03" C6 ROM.
 * Replaced the Power Spikes II S1 ROM by the Puzzle Bobble "d96-04" S1 ROM.
 * Replaced the Power Spikes II M1 ROM by the Puzzle Bobble "d96-06" M1 ROM.

To probably save on manual labor, the unused Power Spikes II V1, V2, C1, C2, C3 and C4 ROMs were not removed.
