This hack alters the behavior of the item “EXP.ALL” to be more consistent with later generations of Pokemon.

In the original game, holding the item “EXP.ALL” caused the acting Pokemon in battle to receive 50% of the experience points from battle. The remaining 50% is divided equally amongst all Pokemon in the party capable of getting EXP. Additionally, a text box would display the EXP gained for every single Pokemon.

This hack deletes the code responsible for dividing the experience equally amongst all Pokemon. As a result, the acting Pokemon receives the initial 50%, and every Pokemon (including the acting Pokemon) receives the remaining 50% without it being divided any further.

In addition, this hack deletes the code which displays the amount of experience points earned. All other battle text is displayed properly.

Finally, EXP.ALL is available for purchase in Viridian and Vermillion cities in place of another item at the Mart. Between both cities, all items from the original game are purchasable plus the EXP.ALL.

Before giving it a try, note that the original game’s EXP.ALL was bugged when calculating EXP for Pokemon in the party when the player switches Pokemon during a battle. This bug influences the EXP earned when switching Pokemon in battle, but the amount of EXP Pokemon receive is still increased by this hack.
