Honestly, it's easier to edit the *.xml files to give you all the powerups you need than it is to use your cheatengine cheat.
D:\Games(or wherever it was installed)\Star Control Origins\Assets\Ships ~ShipComponents.xml you can alter your ship mods. Don't give yourself too many crew slots on your ship, or you'll dump your entire crew to zero every time you leave your command station. Most of what you want to alter is common sense. You still need to find/unlock equipment before you can use it. You can also change the prices and effectiveness of equipment in this file. Don't alter the "startEnabled=" because some equipment won't unlock.
D:\Games\Star Control Origins\Assets\WeaponList ~BasicLaser.weaponlist_xml Change the damage to 10000 and the range to 100 and everything dies in one hit, you don't even need to turn. Pretty much god weapon. It is the 1500 ru point defense laser you can buy from the start.
