Hii I want Rng For A Wild Pokemon In The Grass On HGSS How do i go about it ?
1) Find a spread you want to use.
2) Input the seed into RNG Reporter and choose the method/Synchronize nature/IVs/any other information to narrow down your results. Hit the generate button.
3) Right click on the frame (spread) and click "Calculate Encounter Slots..." Note the number next to "Sweet Scent (Grass/Cave)" and then click the HG/SS Encounter Tables link.
4) Look for the correct area and find the encounter slot. That's the Pokemon you'll end up finding. (So, if you get an encounter slot of 0 and are trying for Route 1, you'll get a Pidgey.)
5) If you don't find the Pokemon you want, look for another instance of the same spread and repeat steps 3 and 4. Using a Synchronizer will increase the amount of frames in which your desired result will appear.
6) Start the game, put a Pokemon with Sweet Scent in your party, get on the bike, then save the game.
7) Start resetting for your seed. When you hit the right delay, do the required amount of frame advances, then use Sweet Scent. Using Sweet Scent takes up 1 frame, so you'll want to advance to the correct frame number - 1.
That should be about it, unless I forgot something.
For HGSS calibration, can I use a code to see a level 42+ pokemon? Just for calibration.
You mean like using a code to modify the level of the Pokemon you find? It might work, but it depends on the code. I can't imagine any level modifier code affecting the PID or anything, but it's hard to say for certain. Either way, it should probably work, so give it a try.
