RNG notes for Easy

GCM Easy RNG:
Memory address for RNG is the two bytes starting at 0x1BE8 (0x1BE8 and 0x1BE9)
RNG gets set to 195 when CAPCOM displays, and set to 62 at the start of the first level.  After that it uses the RNG calculation.

Links for information on the RNG calculation:

Here are my notes for the RNG-manip route I have used for Easy.
Most of those are my own findings, but credit goes to Yurisalgadin and Zekinoma for the new Level 2 route.

Speedrun Tutorial by Le Hulk

Tutorial Any% Easy em PT-BR

Neste video eu explico os detalhes para manipular o RNG, utilizando um recurso de emulador que mostra pra gente como é a interação de troca de variáveis.
Lembrando que não é permitido fazer sua speedrun utilizando este recurso. Use-o apenas para treinar.
