DW:DELUXE! Perfect Playthrough!: Day 15

Battle Megadramon and learn DG Dimension (if not, RESET and try again). NOTE: He'll officially join the city after you defeat Analogman. Get HP Chip.
Auto Pilot back
Quicksave.
Pick up newly grown Rain Plant.
Head over to Tropical Jungle to find Vegiemon (the wilting plant!) and use Rain Plant on him. RECRUIT (+ 2 PP, total: 73)
Auto Pilot back
Quicksave.
Now head over to Factorial Town. Talk to Andromon. RECRUIT (+ 3 PP, total: 76).
Next, go back to Giromon. He has regained his senses. RECRUIT (+ 3 PP, total: 79).
Auto Pilot back.
Quicksave.
Now fly over to Gear Savanna to visit the Card Shop (yes, AGAIN). Purchase all individual Cards and spend about 100,000 Bits on 3-Card Packs.
TIP: If you didn't save 1 Gian Meat at the Item as I told you earlier, then you should get a Gian Meat from the Item Shop here now.
Next, head over to Volume Villa and trade every single one of your Cards for Merit Points. You should have made around 8000-9000 points by now.
Auto Pilot back.
Quicksave.
Now, let's do the most TEDIOUS part in the entire walkthrough! You wanna repeat the previous process 3-4 more times (that is, spend 100,000 Bits on 2-Card Packs, go to Volume Villa and trade them for Merit Points) - this is to DOUBLE your Merit Points from about 9000 to roughly 18,000 and thus acquire 22 Chips! [HP Chip x 4, MP Chip x 4, Off Chip x 3, Def Chip x 3, Quick Chip x 3, Brain Chip x 5].
NOTE: YOU CANNOT MAX OUT PARAMETERS ANY OTHER WAY.
Once that is finally done, Quicksave!
Then feed all of the Chips to your MetalGreymon.
Next, go get 3 pieces (or 5 if lucky!) of Sirloin from Vegiemon's upgraded Meat Farm - these will come in handy to reduce Tiredness while training.
Now you'll need the following items for the next quest (some of them you may already have, others you'll need to obtain quickly): Supercarrot (buy from Vegiemon), HiSpeed Disk (Item Shop), HappyMushroom (you should already have one by now), Giant Meat (alread have it), DigiAnchovy and Black Trout (you should already have these too).
Next, fly to Freezeland and visit the Mojyamon Trio.
Trade all your Items with them, but leave the middle Mojyamon for last (the one who trades Auto Pilot, Restore and Medicine) - this will be the one you want to recruit since he's the least profitable of the three.
The last Mojyamon will join the City. RECRUIT (+ 2 PP, total: 81).
Auto Pilot back.
Quicksave.
Now it's finally time to train your MetalGreymon!
But before that, buy about 20 Hawk Radishes and 20 Super Carrots from Vegiemon to optimize the training.
Then head over to Green Gym start with the training. The idea is to reach 7000/700, then boost each Parameter by 50; and keep following this pattern until you reach 9000/900 on everything EXCEPT Def - which should be 50 less (you'll boost this with the Def Chip you'll get from MetalGreymon at Mt. Infinity).
TIP: When hungry, feed Sirloin.
TIP: Depending on what training you're doing, feed (even when not hungry) Hawk Radish or Super Carrot. REMEMBER that the effect WEARS OFF when your Digimon eats something else. So when this occurs, feed Hawk Radish or Super Carrot again to re-gain the training bonus.
TIP: Remember, Super Carrot enhances training in MP, Off and Brains while Hawk Radish enhances HP, Def and Speed.
So train for the rest of the day (which shouldn't be much).
TIP: When your Digimon get sleepy, DO ONE EXTRA TRAINING and when hitting triangle, keep the button pressed! This way you wont risk getting tired or asking for food or going potty or anything - as the menu screen will pop up FIRST!
Then, Sleep and Save.
