FireRed and LeafGreen Freeze at "This Pokémon is really energetic"

[Someguy1519]

Pokémon FireRed and LeafGreen V1.1/Rev 1 ROMs freeze at "This Pokémon is really quite energetic" at 1 in 64 odds and 1 in 128 odds.

A short pause can still happen with canonical rerolls, but 1/64 and 1/128 should not hard-freeze at the Oak starter line anymore.

If it still happens on the current 2.0.0 build, please open a new issue with:

• exact ROM revision / CRC32
• selected odds
• whether it happens on fresh boot or savestate
• the patch log

To add to this, it unfreezes after a while at 1/256, and the resulting starter Pokémon seems to always be shiny. Convenient, but not if your goal was to hunt for it.

Thanks for the feedback ~

That behavior is definitely not intended.
At 1/256, a short stall can happen, but the starter should not always come out shiny.
So this sounds like a real starter-path bug in the current public 2.0.0 build, not normal odds behavior.
The ROM details help, and the fact that it happens on mGBA/Linux doesn’t really change the conclusion here; this looks more like a patch-path issue than an emulator-specific one.
I’m currently hardening the starter generation paths locally before the next release, so I’m treating this as a valid report for the current public version~
