You'll need a trainer with a Map Spawn XY, but basically you go to your trainer and type in the X,Y coordinates I'll even give them to you.

I Already did the hard part for you. Make sure you put in the (-).
Stage1 Map ID.690000047 X -217 Y-1967

Stage2 Map ID.690000048 X 2869 Y 733

Stage3 Map ID.690000049 X -643 Y -1607

Bonus Map ID.690000050 X 25 Y 553

Go to old kerning, and do Shumi's Third(Final) Jump Quest, this quest can be repeated, I'm pretty sure a trainer on GK has a X,Y Map Spawner. With this method I collected 1Old Maple Coin+Fame within 10Seconds/faster! But basically these X,Y coordinates will spawn you on top of the portal to go to the next room.

Step by Step
1. Start up maple + Trainer(with an X,Y Spawn).
2. Go to old kering city.
3. Talk to Shumi, and you might have to do the two other jump quests before you can do the 3rd one.
4. Put the Coordinates in the X,Y Spawner.
5. Go through the JQ.
6.Repeat.

**Saving your settings tip, if your able to save your setting on your trainer, put in the X,Y Spawn Save, name the saved file anything you want, like Stage 1, then go to the next room put in the next X,Y Spawn then save it as Stage 2 , So on. So basically you just re-load the save settings. This is so you won't have to put in the X,Y code every time you have to enter the next room!!!

I have yet to be banned from this method, so I'm guessing it's safe! But I'm not responsible if you do get banned!!!!
