Second Cheat:Melnorme Credits

If you followed this guide, you have plenty of RU, but the starting equipment you can buy is not very much. The only way you can buy better is to do business with Melnorme (go to biggest stars on starmap and they'll be there), but they don't trade with RU. They trade with special credits, that you can earn via killing creatures or by finding rainbow worlds.
It is impossible to hack credits directly. However, it is possible to hack biological data. Here's how to do it the easiest way.

1) In your base, buy all thrusters and engines, with some weapons and at least two fuel tanks (unless you use this unlimited fuel cheat) and at least two crew quarters. Two extra landers won't come amiss, as well as some more ships. Fill the fuel and crew to the max. You'll do some space travel soon, so yes, this is needed.
2) Fly your ship to Pluto (unless you already have. Hope you were nice to the alien there :) ), land, talk to alien and be nice to him :) until he gives you password (Fluffy-Wuffy-Muffy or something) and joins you.
3)Go to starmap, and find Epsilon Gruis (241.6:368.7) and go to first planet (that's Spathiwa, Spathi homeworld). Be nice to any enemy of Spathi species, use "This is embarrassing, just let me go." or similar option to get there without fighting.
4)Go to moon of the planet, the leading guys are there. Give them password, be nice and accept to rid them of their problems.
5) Go to planet, scan it and land (not too close to green blobs). Do First/New scan in CheatEngine for 0 (zero), shoot the creature in Ur Quan Mastersand pick up the grey/green residue that stays behind them. Do Next scan for 1. It will usually be more than one address, so keep repeating this (shoot the next one, pick up residue and search for 2, 3, 4, 5,6 etc) until you get single address.
6) Double click on address until it goes to lower part of Cheat Engine window. Change the value to some big number (has to be less than 100.000 and you mustn't have more than 150.000 biological data in ship. I'll explain why later.) Shoot another creature, pick up and press shift to get lander back to ship. Dispatch lander again and shoot the rest of the creatures. Once done, go back to the big guys on the moon and tell them you did it. They'll ask you to get back later. Go back immediately, threaten them and force them into alliance with you.
7) Now, fly back to Sol, buy some more fuel then fly to Alpha Centaury. Find Melnorme ship in the system and talk to them. Don't ask them why their bridge turned purple. They'll offer you to sell and buy things. Sell biological data. You'll get a lot of credits. Buy all upgrades from Melnorme you can get your hands on.

That's it.

Notice: Now, the reason why you shouldn't have more than 150.000 (sometimes 250.000) biological data is this: Melnorme credits go only to 500.000, and you usually get 3 or 2 for each unit of data. Once your credits go over 500.000 they start again and sometimes Melnorme will accuse you of cheating ;) when that happens. The reason for this is because you'll never need more than 140.000 credits during game and the response why their bridge turned purple is not programmed. Albeit they ask for 12 million credits, there's no way you can ever get as much. So don't try, because I already did and failed :).
