Final Note

8.5

To the League
Pokémon! 🏆

Explore time fractures and the dark Shadow Realm dimension in this ambitious Hack ROM. Featuring Pokémon up to Gen 9, multi-region and Dark Pokémon, it offers an epic adventure with great ambition and upgrades.

✨ Super Effective (Pros).

Original and innovative story with temporal fractures and the Shadow Realm dimension.
Extensive content integration: 1st to 9th Gen Pokémon, multi-region exploration and return of Dark Pokémon.
Numerous quality of life improvements: MO removal, visible Pokémon, DexNav, expanded storage and rebalanced difficulty.

🔻 Not very effective.... (Cons)

Limited content as it is a demo that only goes up to the second medal.
The English language can be a barrier for non-English speaking players.
Although polished, being a ROM hack, it could have bugs or instability inherent to an unofficial project.
