Hello, sorry if this is discussed in another thread, but I'm going crazy looking for information and I can't find anything.

I recently bought a GBA cartridge with a 118 in 1 multirom in which it seems that the first three games are GBA games and I think the rest of the games are NES bootleg (PocketNES as far as I understand). I have tried GBA Backup Tool for Nintendo DS trying to extract the ROM, just as I have used FlashGBX, but I always get the same result: I can get the ROM menu where only the first game (Pokémon) works but the rest cannot be played.

On the other hand, I have a 34 in 1 Game Boy game (although it says Advance on the sticker, it is for Game Boy Color) that I don't know how I can extract it either, I have also tried using FlashGBX where I can only extract the menu from the ROM but no game works.

I am attaching the failed ROMs and photos of the cartridges so you can see what they are (the GBA version is too big). How can I extract both ROMs from these physical games? Thank you very much, and sorry for my bad English.
