Meet some tough problems about GC Pokemon Box RS emulation and connection to GBA

[Test!ng]

Hi everyone! Actually I really appreciate Dolphin team's effort on the development of this excellent emulator, and thanks to your good work we can emulate the GameCube Pokemon series better than ever on PC, like Pokemon Box Ruby & Sapphire the USA version, Pokemon Colosseum and so on. Especially Pokemon Box USA version can now be emulated nearly perfectly on Dolphin, with normal gameplay and connection to GBA (via VBA-M). 
Unfortunately, I meet some difficulties in running the Japanese version Pokemon Box on Dolphin, which doesn't work well in even normal gameplay (can't enter storage system without special Memory Card 59) or connection to GBA (stop on the step launching the GBA bios unlike the USA version). It's a regret that JPN version of GEN3 Pokemon series (RSE/FRLG) thus can't link to Pokemon Box on Dolphin ... I'm looking for your help and below are the details of the problems about the JPN version Pokemon Box emulation on Dolphin:

----Problems----

1. To normally play the JPN version of Pokemon Box RS on GameCube, a special memory card with 59 blocks called "Ruby and Sapphire Memory Card 59" is required just unlike the USA version, and without it we can't start the storage system gameplay (pic 1).

However, I haven't figured out any Dolphin's function to produce this special memory file, which the USA version doesn't require (pic 2).


2. Dolphin works well on connection to VBA-M using Pokemon Box USA version with Ruby/Sapphire USA version, and we can see the introduction part of Ruby/Sapphire will play normally after the GBA bios finishes its launching on the GC screen (pic 3&4).


But Pokemon Box JPN version doesn't work with JPN version of Ruby/Sapphire, because the GBA bios running screen will stuck and lack the "Nintendo" logo below (pic 5). 

I try to enable the Panic Handlers (go to "Options" -> "Configuration" -> "Interface", and leave "Use Panic Handlers" checked), finding it generate error logs continuously like "Invalid read from 0x900000b4, PC = 0x800b6084" the instance you close it (pic 6). 

Same situation takes place in the Europe version of Pokemon Box and Ruby/Sapphire too. Similarly, someone with the same problems had also posted his question, and more details can be found on this link.

Additionally, the dolphin version I'm using is 5.0-2510 x64, and the VBA-M version is 2.1.4-36e61d76, both of which works well and stably with the USA version of Pokemon Box and Pokemon Ruby/Sapphire, but doesn't with the JPN version. In the end, I look forward to your reply.
