EXECUTE.

[TwilightStarocean]

yes

[smashbro596]

yes

i dont expect everything to be made at once, but over time.

[Casu Consulto]

I'm excited for the Steam release of the MMBN collection! I hope someone creates a table quickly!

[Mizu]

I've been looking at this myself now the Steam release is out, and thus far can only modify Zeni in BN1. Timer and rank for netbattling eludes me, and I haven't bothered with battlechip number modification yet. I imagine you could also tweak HP & PowerUP count for Megaman, alongside how many chips show up each turn during battle? Plus having the turn gauge fill instantly.

The game speed modification feature in Cheat Engine also doesn't seem to be playing nice, failing to work at all. Unsure if that's due to something on my end or from the game having Denovo security.

  Update 6: Added Subchips, BugFrags, Style, and P.A Notes code address for MMBN 2 & 3. Also added Navi Customizer Blocks for MMBN3.
  

  Previous Updates

  Update 5: Updated Drop code for MMBN4. Now includes section for second possible drop, number of drops, and values for Bug Frags and Zenny's. Just make sure to freeze the values before battle ends.
  
  Update 4: Added Chip List of MMBN6. Changes only work when you are NOT in any menus or battle. Saving any changes will also update the library.
  
  Update 3: Added Chip List of MMBN5. Changes only work when you are NOT in any menus or battle. Saving any changes will also update the library.
  
  Update 2:Added something for MMBN4. This game seems to have some very severe CRC checks so the best method I could find to add Chips is by modifying what chip drops at the end of battle.
  
  This needs to be tested by other people as it seems like the Emulator the game runs on seems to always grab the same set of addresses for the game. Trying to find pointers for the address seems to return 0 results for me, so hopefully someone has better luck finding it. Otherwise if the address or the way the emulator works changes, the code will stop working.
  
  Update 1:Added Chip List for MMBN 3.
  To update library changes you will need to get a new Chip. A
  Any changes to qty for chips not in your Library will cause the savefile to Break, so make sure to update the Library first
  
  Here's some stuff for the Chip Library for MMBN1 & 2.
  MMBN3 will take some time as the game keeps crashing and breaking when I play with the code.

  Spoiler

  Sorry for the machine English. I got Beast Link Gate mark in Japanese version Gregar and Falzar.
  
  Gregar
  80205abe:F800
  
  Falzar
  80205abe:0700
  80205ac0:00c0
  
  After entering these cheat codes in the cheat engine, save and return to the title, and the mark will appear.Based on the cheat code for the Japanese GBA version, you can easily find it by varying the memory address.This is the cheat code site I referred to.All BN cheat codes are listed.
  
  raid.s500.xrea.com/code/gba
  
  And I will upload some cheat codes I have searched.
  IDK name of "１００人斬り" in English version, so I hope someone translate them.
  Please look up the internal ID from that URL.
  BN6 is still in the process of researching. More codes may still be added.

  Here's my table, I added a pointer for the custom gauge so you can get instant turns, total chips in battle so you can always have 15, and infinite health. Let me know if there's anything weird happening with the health script. I'll see if there's anything else that catches my eye as I play.

Niihiiliist, Here is a updated table that included more items.

This is completely your list, I take no credit for it.

Each item is Byte and not 2 Byte which is why you weren't able to see them when searching.

[smashbro596]

can we at least find the health, zenny, and bugfrags for all games before we worry about the chip amount?

yes very much yes

It seems like if you add 10 to each address, it will give you the next type of chip. If you add 1 to that first chip's address you will get the different letters of the same chip(up to 5 total)

ex: Cannon A = 80204250, Cannon B = 80204251, HiCannon F = 80204260, HiCannon G = 80204261

Nah, I don't care about credit, the more people contribute to the cheat for this game, the better. Also, you're a lifesaver with the addition of the chip cheats, now I won't need to waste my time hunting those pesky V2/V3 Navi chips.

Here's a quick have all chips script. Note that this also gives you the debug chips as well. Be careful with it and backup your saves, I used this on the GBA version of the game and don't recall it having any issues, but never hurts to be safe.

Building on the work Made by Niihiiliist and Made by KronosHelix, Here's an update with all the chips I've encountered so far. zachillios's script is probably more useful if you want quick and dirty all-chips, though.

Seemes Zachillos' code gives the Program Advance as part of the battlechips in your Sack, which surprised me; didn't know those were treated as chips internally. That said, while both battlechip codes give them to the sack, it doesn't affect the in-game library for chip data. Guess we'll need a different code for that.
