How to go on the Trainer Tower? (PPE)

[Etto]

Hello everyone.
At the seventh Island, there's a Trainer Tower, but I can't acess it, a door block the entrance.
There's a solution to go inside, cause I would like to try this Tower ^^
Thanks

If I had to guess, it may be blocked intentionally. As in, the romhacker had no intention of finishing Trainer Tower. I haven't played PPE (or Fire Red) in a long time so if someone can confirm or deny that I know what I'm talking about, that'd be awesome.

Unfortunately, I never got to the Battle Tower in Puppet Play, but I'm pretty sure in Fire Red, the trainer tower is accessible as soon as you get to it.

...Not really much better than Shanks' answer, unfortunately, but his guess sounds good to me is what I'm saying.

It's intentionally blocked off as the data structures are different from regular trainers and thus was not easy to edit at the time.

The only purpose the tower serves now is to sell all TMs.
