List of Mega Man Battle Network 3 upgrades

This page is for all the upgrades in MegaMan Battle Network 3 and their locations.

HP Memory
Attaining an HP Memory increases your Maximum HP by 20 each in all Battle Network games. HP Memories are often found in net merchants. Net Merchants often sell 3 HP memories. The first merchant in ACDC Area 2 sells the very first buyable HP Memory for 1000 Zenny. Some are found as mystery data as well as in special hiding spots in the real world. They can also be found as a reward for a Job.

Regular Memory Upgrades
Also known as Reg Up, the Regular Memory Upgrades increase the memory space as to which you can select a specific battlechip from your folder to use at the beginning of every battle. The number you will look for is labelled MB. Reg Ups can be found in many places throughout the net in mystery data. They can also be found in hiding places as well as be given as a reward from a Job.

For example : The Cannon battle chip has a 12 MB. If you have 12 MB or more collected, you may go into your folder, go to the cannon battle chip (assuming you have the chip in your folder), and press select. A red box will surround the name and information of the chip. From now on, every battle you start will have that same cannon as the first chip to appear in your folder.

Remember : It is still a regular battle chip. It does not have any special properties.

Expansion Memory
Expansion memories expand the size of your navi customizer (Navi Cust). There are only 2.
 * The first one is obtained before the N1 from an e-mail from dad.
 * The second one is obtained by completing the gang members side quest.

SubChip Memory
