SO, here it is! The mighty location list!
https://spreadsheets.google.com/spreadsheet/ccc?key=0AuFWDSHDcYsrdGw5WWViR0dwaDEtSjdPc2J3WWpjX1E&hl=en_US&authkey=CKnxkcAE
Roland should be posting the downloadable file to the main page sometime soon, but since this is already here, I'll give you the deets:
-This spreadsheet is a direct transcription of the pokemon location file that's used in this hack. I did my best, but spreadsheeting is kind of mind-numbing, so there may be the occasional error. Let me know if you find one and I'll fix it.
-Next to each pokemon I've noted the locations that include them.
-There are even handily color-coded (see legend at top of spreadsheet).
-If a pokemon could be encountered in multiple ways at a single location (e.g., both Walking Anytime and Walking Night, or Walking Anytime and Surfing, or Old Rod and Super Rod) I only bothered to note the first method. If you're looking that hard for a single pokemon in a single location, it might be worth trying different methods/times.
-I only bothered to note down a maximum of eight locations per pokemon. I mean, do you really need to know every single place you can find a magikarp? If you're having that much trouble finding one, you may need more help than I can give you.
-This list does not take into account pokemon that you can get through the underground, mass outbreaks, or the trophy garden. Almost all of those are available in the wild anyway.
-For all of the legendaries that you get either through the plot or event items, I just made a note of that.
-I've noticed that there are some inaccuracies in the location file's documentation. For example, Iron Island Cave B2F Left and Right should be reversed. The spreadsheet does not reflect this. Also, some pokemon that SHOULD be able to be encountered at anytime only show up in the morning (bastiodon is the only such one I can confirm, but I suspect others). If you're having trouble finding a pokemon at the location/time noted on the spreadsheet, it may be worth trying other methods/times.
-The following pokemon are not available in the wild and must be bred, evolved, mined, or trophy gardened:
Ivysaur
Charmeleon
Wartortle
Blastoise
Weedle
Wigglytuff
Persian
Alakazam
Exeggutor

Aaaaaaand I think that's it. Whew! I hope that this is of some help to future Perfect Platinum players.
