The bee items are hidden at certain locations in the stages, you can see their locations by shooting your bullets/laser towards them, they will glow when bullets/lasers pass through them. However they can only be revealed when they get hit by the front part of your laser.
Once being revealed, the item will change its color by the following order:
Green-->flashing-->yellow-->flashing-->green-->...(repeat)
In iPhone mode, green bee will move your SM gauge towards M, yellow bee will move the gauge towards S, flashing bee will fill your hit counter instantly by 150 (very important for scoring!)
In arcade mode, green bee will fill your hyper gauge by 1/4, yellow bee will give you very high score points, which are also multipliable based on how many yellow ones you have already acquired. Getting the bee when it's flashing will grant you both merits from green and yellow ones. In arcade mode, when you collect all bees without dying or using any bomb in one stage, the score you earned from the last bee will be doubled (e.g. if you get the last bee when it's green, on the screen you will see "100X2") with a significant larger font, so it's easy to tell whether you missed one or not.
For those people who are struggling to unlock Hibachi, I would recommend practicing collecting all bee items in arcade mode (as I said, it's easy to tell if you collect them all), and switch to iphone mode when you have remembered all the locations. Just remember that you have to play in NORMAL or HARD and collect all 45 bee items to enter the hidden 2nd loop (= fighting Hibachi)
In order to enter the hidden route in stage 1, you only need to meet the following conditions (Arcade mode):
1. destroy 3 silos (if the silos are destroyed by the tanks they don't count)
2. By the time that the third silo is destroyed, the hyper must be completely filled
3. no miss till you destroy the the third silo.
For iphone mode, you only need to meet 1 and 3, you don't have to fill the hyper.
You can also enter the hidden route when you successfully collect all bees with no miss in two consecutive stages. For example, if you failed to enter the hidden route in stage 1, but you've successfully collected all 2X7=14 bees in stage1 and 2, you will enter the hidden route from stage3.
When you successfully enter the hidden route, you WILL STAY in the hidden route unless you furfill BOTH of the following conditions:
1. fail to collect all bees in the stage
2. Die or use bomb(s) before you defeat the mid-boss
If BOTH of the conditions are met in one stage, you will be kicked out of hidden route from next stage. But as long as you can prevent either of them happens you'll be fine.
These pieces of information (except for the iphone mode part which is done by myself) are translated from CAVE Dodonpachi Resurrection Official Guide, so their reliability are guaranteed.
Trying to get the "Clear all modes with all ships" achievement, but even I all-cleared iphone mode with 4 ships and arcade mode with 3 ships X 3 modes=9 combinations (I even beat the 2nd loop with most of the ships), I still can't get the achievement. I hope it's not a bug or that you have to clear the 2nd loop with every ship/combination, that would be insane.
