This page is a list of glitches that appear in Mega Man Battle Network 2.
Major glitches
Folder2/Folder3 NetBattle glitch
In the initial release of Battle Network Rockman EXE 2, a glitch appears where chips in the second or third Folder can be lost in a linked NetBattle.
When a NetBattle is lost, the game picks a random chip out of all chips the player has, excluding the ones in their Folders. However, in the original version of Rockman EXE 2, does not exclude the chips in Folder2 and Folder3, only excluding the ones in Folder1. Due to this, a chip in either of those Folders has a chance of being forfeit to the opponent. If the player has no other copies of that particular chip in their Pack, the chip will remain in the Folder until it is taken out, at which point it will vanish after closing the Folder editor.
This glitch was fixed in the Japanese 1.1 version of Battle Network Rockman EXE 2.

Minor glitches
Flappy AI glitch
In the final version, Flappy almost always does a ground pound after its second jump. However, its AI is bugged; the amount of times Flappy jumps before doing a ground pound was actually supposed to be much more variable. The game stores the ground pound chances in an 8-bit array, but due to a mistake on the programmer's part, this chance is loaded as a 32-bit integer. This causes it to overflow and always be 100% after the second jump.
| What should be happening: | Jumps | Chance to ground pound | |
|---|---|---|---|
| 1 | 1/8 (12.5%) | ||
| 2 | 1/8 (12.5%) | ||
| 3 | 5/8 (62.5%) | ||
| 4 | 7/8 (87.5%) | ||
| 5 | 8/8 (100%) | ||
| What is actually happening: | |||
| 1 | 1/8 (12.5%) | ||
| 2 | 263688/8 (32961%) | ||
Flappy appears again in Mega Man Battle Network 5 with the new name Powie. In that game, this bug was "fixed" by simply never letting Powie jump more than twice; however, it introduces another bug which reduces the chance of it only jumping once to near zero!
