Expected Behavior
the game should run normally and without excruciatingly long wait times when opening your bag, moving through items in your bag and exiting the bag, battles should be of normal speed.
Actual Behavior
the game has unusually long wait times when transitioning between menus and increased slowdowns in battles.
Steps to reproduce
Run the game in DSi Mode, in the main menu, when you are asked if you want to enable the "C-Gear" functionality select "Yes" (note: if you haven't obtained a C-Gear yet the prompt may not appear), once in-game, press 'X' to open a selection menu, select "Bag" and once loaded press 'Up' and 'Down' to move through the items in the Bag, then press 'B' to exit the Bag, you will notice and unusually long wait time.

Other notes
the cheat codes applied have no impact whatsoever on the issue. also, I'm not sure but the SD Card shouldn't be at fault here.
Will you be available for future issues and/or replies?
Yes
To add to this, it also prevents you from accesssing bootloader settings. This issue also appears in normal ds mode. Happens on v1.4.0 & 1.5.2 nds bootloader versions for the following systems *DSI XL *O3DS *O2DS
Is it way worse than it was on older versions of nds bootstrap? (1.2.1-1.3.2)

Fairly certain that would be intentional behavior; wireless and multiplayer need very strict timing to keep the connection in sync and functional, which originally is the reason why these games had slowdown when c-gear is enabled. Though it sounds like the slowdown got way worse in newer version of nds bootstrap?
Opening the in-game menu while wireless functionality is in use would desync and break it, so when wireless functionality is in use I guess they intentionally disable the in-game menu from opening.
It's just unfortunate that gen 5 pokemon keep a wireless connection open in the background when the c-gear is enabled, because it ends up making it so you can never use the in-game menu at all, and forces the entire game to slow itself down at all times.
I wonder if it would be possible to detect when a connection is being made to another ds, and only slowdown gameplay/block in-game menu when a connection actually exists between two or more players.
which originally is the reason why these games had slowdown when c-gear is enabled
@Ammako except that the original games DO NOT have a slowdown when the C-Gear is enabled; or if they do, it's so small that it's unnoticeable during normal gameplay. although i didn't specify it in the issue, this slowdown doesn't occur in DS Mode (or if it does happen, it's no way near the unforgivable slowness of DSi Mode) implying something is wrong with the DSi Mode, this problem should be carefully looked at because it probably affects other DSi Mode Software other than these specific games.

But you're not playing from a retail cartridge, are you?

Again: is this slowdown worse now on 1.5.0-1.5.2 than it was on older nds-bootstrap?
But you're not playing from a retail cartridge, are you?
i don't understand what this question is trying to achieve as the issue stands with the fact that there is a slowdown that shouldn't be there, because it doesn't exist on the retail cartridges.
that makes sense but it still doesn't justify the IMMENSE slowdown compared to retail cartridges.
Again: is this slowdown worse now on 1.5.0-1.5.2 than it was on older nds-bootstrap?
i just tested with nds-bootstrap v1.3.2 and the slowdown is the same as v1.5.0
I don't know what else to tell you. The slowdown is there on purpose because otherwise the wireless communications wouldn't be able to function. That the Gen 5 games behave like this is already known, and if it could be fixed without breaking the wireless functionality, it would have been.
Try 1.6.0, it should be 99.5% fixed

i just tested with this version, as the release information suggests, there appears to be a minor slowdown, only on B/W2 (not 1) main menu, at the end of the main menu cycle, the animation progresses past the intended stop where the animation of when you press a button to continue is shown, before going back to the cinematic intro, as for the main issue:
i'm happy to say that the slowdown is almost entirely gone, the worst offender right now is scrolling between items in your bag, as for the loading times, it looks solved, battles, also solved, i'd like to note that for some odd reason running the games in DS Mode is always faster, almost killing the slowdown entirely.
this issue should be looked into, but as for the "severe slowdown" the problem is solved.
