Yes, you can use an existing save file on a new GBA ROM as long as they share the same title and are for the same game.
You just go to the right link and click download and run or save both side and it will start downloading the rom you need the NO$gba to play it not only no$gba and you click in rom and click extract here then you open no$gba and click on the rom that is the rom not the one you download its the file of the rom you just click the file that is the other side of it right and start play enjoy :)
No, but you can go to romulation.net and search for a flipnote.nds (rom file) and then download it. But inorder to use the rom file you must download a no$gba emulator or a DeSmuMe emulator and then open the rom file from there. Best of wishes to you to get to play around with flipnote on your PC. *If you have a Macintosh or Linux computer, you may google or yahoo search "flipnote .nds rom for mac" and "DesSmuMe emulator for mac" [or] "no$gba emulator for mac" or "flipnote .nds rom for linux" and "DeSmuMe emulator for Linux" and "no$gba emulator for linux".
The only way that I know of is to check in the ROM file name (if it has (U) in it, it would be USA, and (J) for Japan).
turn it off, take the GBA game out and make sure Pokemon platinum is in. Turn it on and select Pokemon platinum and - VOILA! it starts.
You can't.
copy the Pokemon ROM file, go to no$gba and find the battery file, then paste the Pokemon game into the battery file. start the game like you normally would then save like you normally would then start it back up again and bam! it should be right there. this works for every Pokemon game.
go to doperoms.com and search for the game you want to download then extract the file using winrar and you have a gba rom!
download a Pokemon gba ROM and no$gba
you download the randomizer, download an emerald ROM and an GBA emulator for mac, then you run the randomizer and go to File, Open, then select the emerald ROM, set the settings you want, and then file, save as. Play the new ROM you made with your emulator and you'll be good to go.
To play it, all you have to do is on the emulator, go to file > open > choose your ROM (Gold) and start playing. If you have VBA, you can choose your controls from Options> Joypad > Configure > 1.
The game system it is for. The gba ROM is for Game BoyAdvance. The Nds is for Nintendo ds,dsi,ds light .The programs used to play them also differs
You have to buy an adapter. Also giving the rom to others is a crime. It is legal ( in some countries) to keep a copy for your own personal use as a backup.
