>>35866172Thanks, anon. Reporting back.
Took all night running the script to get shiny Entei. All night and then some, actually. Woke up to pic related this afternoon.
The script paused the emulator for me, too. Forgot to turn it off before I tried to catch it, so it threw a regular fucking Pokeball at it for me. Had to track it down again manually, but at least the shiny was already locked in.
With all that done, it's time for Suicune next.
