Btw, if i remember correctly, you have to change the evolution data for eevee. In GSC, there is a byte that determined how they can evolve. Eevee have 5 evolution data, the first data goes like this:
1st byte - determined the evolution by stone/item, trade, level-up, happiness, etc
2nd - etc :P
3rd - etc :P
Not really, until I learn ASM to get the extra two evoloution shards for Eevee working, Redux is stalled.(Unless I alter the 'code' to have Lunaeon evolve with the Moon Stone and Solareon with the Mist Stone.) The Mist Stone would just replace the Sun Stone but any other item edited to act like an evo item doesn't work.
