Thanks for the reply Okay, I will definitely report this bug.

Gba Slot In Desmume

While inserting a cartridge into a DS Lite's GBA Slot. You may notice that it sticks out slightly. Do not try to push it in completely, as it may damage your console. The ds has the possibility to play gamboyadvance and nintendo ds games (duh) the slot wherin you insert the ds game is called slot 1. Slot 2 is on the bottum part of the ds and thats where you insert your gba games Slot 1- Nintendo ds games. If you have other Slot-2 cards, you usually run nds.gba. Slot 2 Flash Carts are GBA cartridges that have Removable Storage inputs, such as micro or miniSD (Image 3). But if you boot it from the main DS menu, it will boot as a GBA game. So you need a PassKey, which makes your DS think it's a DS game but really just boots from the GBA Cartridge.

Well, after googling alot, I stumbled upon this info -

I've figured out how to make the migration option to appear when using DeSmuME (current v0.9.4). As you probably know this emulator supports GBA-NDS linkage since some builds ago. However it was not working for Pokemon D/P/Pt so far. Migration is still NOT possible though (save corruption message), but you get the benefits of 'dongle method' (depending on 'inserted' GBA ROM you get additional pokemon in-game).

I look forward for cory1492 comments/suggestions. It seems just a matter of a better/proper FLASH save access support on the emulator itself to be able to interact with the GBA sav on the HD. But I lack the required tech knowledge to 'describe the problem'.

I've only tested with Pokemon D/P ENG (ADAE/APAE, US or EUR, it doesn't matter)

Requirements:

1. NDS BIOSes (both ARM7 and ARM9 dumps)

2. NDS save which allows migration (you have the National Pokédex and are able to enter Pal Park)

3. NDS ROM patched with Pokepatch v4.2 by cory1492 -->OR<-- clean D/P/Pt ENG ROM + 'Dongle Method Only' AR code by cory1492 (see below)

How to:

1. Go to 'Config->Emulation Settings'. Enable 'Use external BIOS images' and browse for your ARM7 and ARM9 dumps. Enable 'Emulate SWIs using BIOS images' (not strictly required, but it won't harm).

2. Go to 'Emulation->GBA slot'. Select 'GBA game' and browse for your clean GBA ROM of choice (R/S/E/FR/LG). Remember that: migration requires that GBA ROM language matches that of the NDS ROM. However dongle method works for any language combo. Ideally you should also have a proper GBA save (128 kB) named like the GBA ROM, but as I've said, on accesing the migration option you get a save error anyway (lack of proper GBA FLASH save access emulation).

3a. Load your patched NDS ROM -->OR<--
3b. Load clean D/P/Pt ENG ROM, wait for the titlescreen, pause emulation, go to 'Emulation->Cheats->List' and enter the following AR code

020DC50C E3A000C2 020DC500 E3A00009 (for D/P ENG)
020D1564 E3A000C2 020D1558 E3A00009 (for Pt ENG, NOT tested)

After entering the AR code you have to *reset* and unpause emulation.

The 'Migrate from R/S/E/FR/LG' should appear now. As I said you can't migrate yet (GBA corruption error), but corresponding dongle pokemon are now available.

More Dongle-Only AR codes are required for JPN/FRA/GER/ESP/ITA/KOR versions, so Pokepatch should be the way for them (maybe cory can disclose those AR codes). However from the emulation point of view the save access patching applied by Pokepatch should not be required, but only better/proper emulation support for GBA FLASH save access on DeSmuME.

It is not possible to migrate pokemon from LeafGreen/FireRed/Emerald/Ruby/Sapphire to D/P/Platinum:
