Combine Trainer escape glitch and bad NPC routes for non Level|roster 1-7 Pokémon and Trainers

In using a bad NPC route (available by talking to Pewter Museum and Pewter Gym NPCs from the wrong coordinates, and theoretically from Professor Oak stopping you at Route 1 with bad coordinates), we can corrupt CD2D/CD2E; the addresses that control the Pokémon/Trainer and Level/Roster you receive from Trainer escape glitch respectively. These depend on the type of 'bad NPC route' you use (i.e. your coordinates; the path pointer that follows the coordinates).

You must ensure a) that you can open the Start menu (change boxes before using the bad route) b) that you use a good route after performing the bad route, before flashing the Start menu and returning to the Trainer escape glitch route to get your encounter.

Thanks to the research of TheZZAZZGlitch, we can also reliably customise this to encounter almost whatever Pokémon/Trainers you want; such as Mew Level 254 by talking to the Pewter Museum guy from a certain position in Red/Blue with a specific item 3 and item 4, with item 4 controlling the path pointer. When this is in RAM, you can use a RAM address of your choice for the species/level etc. as long as no 0xFF appear on the way.
