hi all new here Right I’m new to this rom thing I’ve got a flash card with the Pokemon 10 anniversary preloaded on it but I would also like the berry update and mew on there but would not know were to start and was hoping maybe if I pay post each way that the guy that posted the Pokemon YouTube videos could do it for me please as It was originally the purple cart
What flashcard do you have? some have an SD card in them so its just a case of copying the rom on to the flash card. Others have to be re flashed by software on a PC.
I'm pretty sure that just has a Micro SD card in it. Use a PC / Laptop with a card reader and copy the rom on to the Micro SD card. You might need to patch the rom first as per this video, however i'd try copying a new rom on to it first and see what happens:
