Is there a way to extract the .mb files from .gba roms?
I've become rather addicted to Panel de Pon, but could easily go without this flashy intro/menu...I haven't tested this, but I think you could try to find a pointer table in the rom with a hex editor and find out where the start address of the game you're looking for is located, and then just strip the file, and add a header.. The thing is, it might be more complicated than that if they had to modify each multiboot game for the compilation...
Not that easy, unfortunately, since the Eurasia guys have compressed the games in their ROM. They also were hacked to work with the Menu. Here's how to extract NES ROMs from that ROM (doesn't work for Panel de Pon, though):
1. Fire up VBA
2. Load GameCube_Multiboot_Games_Internal_GBA-EURASIA / EUR-MBGC.GBA
3. Start the game you want to have as single file
4. Start the Memory Viewer ("Tools" -> "Memory viewer...")
5. Click "Save"
6. Enter following values: Address = 02000000, Size = 40000
7. Save as whatever you want (it'll get *.dmp extension anyways)
8. Fire up your favourite Hex-Editor
9. Search for "04 F0 1F E5 C0 00 00 08"
10. Replace with "01 C3 A0 E3 00 22 9C E5"
11. Save with *.mb extension
é voila, you got a working Multiboot image now which you can load with Flash 2 Advance Writer, Pogoshell or whatever you prefer. You may want to truncate useless 0s with your favourite util now, as "Size = 40000" from step 6 always generates a 256 kByte ROM with lots of overhead.
Yeah, I know, this is kind of useless since it only works with the games you can play with PocketNES anyways and not with Panel de Pon, but maybe there are one or two people here who find that info helpful... I really couldn't care less if you don't.
