===Hall of Fame entry bootstrap===

If the player views a Level 211 [[GlitchDex/RB:195|h POKé (0xC3)]] (getting one at this high of a level is possible with [[Rival LOL glitch]]) in the Hall of Fame, it will write C3 18 D3 to (jp D318) at CD3D, so using the item will execute Pokédex flags (from seen 113, and then the player's inventory data). Certain combinations of Pokédex flags will make this region unsafe, so to prevent issues it's a good idea that Pokédex entries 113-152 are not seen at all.

Certain combinations of Pokédex flags will make this region unsafe, so to prevent issues it's a good idea that Pokédex entries 113-152 are not seen at all.

Using another level for the h POKé is also an option, such as 219 to execute DB18 (current PC box Pokémon 5 PP of Move 3). It may also be possible to use a different glitch Pokémon representing a conditional variation of the jp opcode (C2 (jp nz), CA (jp z), D2 (jp nc), or DA (jp c)) depending on the state of CD38-CD3C (all flags are reset by default, in which case CA and DA wouldn't work).
