The AI for enemies in the overworld is controlled by predetermined spawn points which can also have paths they follow walking around. They notice the player and can break from that path. To my knowledge, we don't know enough about the pathing files to actually make that work.

Due to the way the mod.cpk patch works, you can only replace files, not delete them.
However, mostly empty files usually do the trick.

The navi is special however, and the methods I know of are:
Manually the bitflags via flowscript
Setting the navi bit on every encounter ID
p5_DisableNaviLines

Well, actually, that's a relatively early proof of concept mod.
The actual mod, called the Mod Menu, is now an essential part for modding p5.

I'd recommend going to the main page, the guides can help you install the mod menu

Ironically I've been working on the very same thing. It's not as easy as with TTYD See, one major problem is the fact that it's completely inconsistent how/where the story bf/msg's are placed. Another huge problem is the fact that all messages are stored like: [dlg MSG_001_0_0 [Sojiro]] [s][bup 0 10...

I'm amazed you went through the entire process of making loop points for THIRTY-FOUR SONGS

Mad props

IIRC, the section of code the random music mod is trying to change conflicts with some read-only code in RPCS3, which is why CheatEngine is needed to change RPCS3's behavior to accept the patch.

With this restriction, the hacky method is the only RPCS3 method currently.

Technically you could get a invite link, but it turns out that if you make enough posts on this forum, a link for the server'll appear on the main page, so I'd say that's the best bet

Not exactly.
The mod menu's source is open to modify, it'd be pretty easy to put in the code for that yourself.
I've got several custom functions in my mod menu, and just repeating the time slot seems easy enough, if i'm not missing the point.

It's not currently something in the mod menu, but it's not particularly challenging to implement. However, why anyone would need that is still up to question.

Sorry for the necropost, but surprisingly there might be some good developments for this question as of recent. Been working on transparent DDS support, and I do have a proof of concept proving that the battle menu can be replaced with a 2d image. If it's just the battle menu your looking to replace...
