Some story events rely on precise timing. If you sprint past a trigger point at 6x speed, the game might not register that you entered an area. This can break quests.
Pokémon Solar Light and Lunar Dark run on the Pokémon Essentials script pack for RPG Maker XP. Unlike standard Game Boy Advance (GBA) or Nintendo DS (NDS) ROMs, these are native Windows executable ( .exe ) files.
Best practices for using Speed Up safely
This is the most common method for RPG Maker fan games. By attaching Cheat Engine to the game's .exe process, you can enable a "Speedhack" and set a custom multiplier (e.g., 2.0x or 5.0x) to speed up everything from walking to battle animations.
