No there is no hack. I suggest you to download from here the Armjld Trainer, and go for "Fast Exp & Gold" (requires J6 saga complete until Datadisk 4 i guess). It will get you about 1000 exp and gold (in 1 minute, you get about 10k gold and exp). Or, with Le Bot, go with Banished Exp & Gold. 600 xp and gold.
Step 1: Spam this packet:%xt%zm%getMapItem%4%365% - Gold Boost.
Step 2: Spam this packet:%xt%zm%getMapItem%4%366% - EXP Boost.
After you have clicked accept. Stop Spamming the codes.. you cannot have more than one of each.
Step 3: Start Banished EXP + Gold.
Step 4: Activate Boosts.
***NOTE**** Le Bot 5.8 currently has the fixed version of Banished XP+Gold. Get Le Bot 5.8
