I'm still supporting this, but not actively working on new features. Gen 1/2 -> 3 Pokemon are legal for in-game purposes, but will never be competitively legal. What caught location should a Slowpoke caught in Slowpoke Well have in Gen 3? There is no 'legal' possibility in the Gen 3 location data. If you wish to hack the PID etc to be legal in the cases where you can find a legal catch location, feel free to do so but there's no point implementing any form of 'legal' generator when the Pokemon are not and cannot be legal.

Now deleting Gen 2-exclusive moves in the Gen 3 transfer could be possible, but were Nintendo to have supported Gen 2 to Gen 3, then as with every other bridge, the gen 2 moves would not have been deleted.

Perhaps a 'Make Legal for Gen 4 on' option could be viable. My first thoughts are to use a massive lookup table of [neutral] PIDs and caught locations, but getting that to match the trainer ID would be hard. It would be a huge task that wouldn't be worth the end result, whereas Gen 2 to 3 I feel is, since this has never been possible before. If someone would like to collate a huge collection of valid PIDs, or suggest an alternative I'm open to ideas and happy to share API and codebase, but it's not as easy as just saying 'Make it Work for Gen 4' as the program supports Gen 1, 2 and 3 exclusively and that's all I'm prepared to do for free lol.

Of course, any amount of programming done is really done because the programmer wants to see it done for his own purposes. The fact that you've shared is nice enough, and I'm not going to be demanding. For my own purposes, I probably would to like to have competitively legal mons, so I'll just figure out a way to do that with time.

In my own mind, I wonder if it possible to hack locations in Gen 3, because of Firered and Leafgreen. I was able to trade mons to Emerald back in the day without any problem whatsoever, so I was wondering if you wouldn't mind explaining to me how the location data works for that.

If not, then thanks anyways for what you've done with this.

If you are still working on this, would you consider making this so that transferred mons can be legal? This is something that could really come in handy for those doing runs through the various gens, although it is already helpful for that.
