GBA Flash, Linkers, Carts, ROMs etc

I've been reading about these gba carts & linkers and emulators etc. It's all kind of confusing if you haven't been following the development from the beginning. I have a gba sp and want to be able to backup my games and to consolidate these games onto 1 cart. You guys are the experts, what would you recommend today? I see 512, 1gb, 2gb etc carts and link cables, readers, emulators etc. Man it's a mess trying to figure out what I could or should use and these carts are expensive. It looks like, with the right emulator, I could play the gb games on my pc, that would be cool and also that I could down load home grown gb game, that to would be cool. I don't want to invest my hard earned $ on the wrong stuff. Any help would be apprecitated.
Thanks

You've got a distinction here that you may want to make first: NAND based or NOR based. Carts that use NOR flash are slow to write to, have limited capacity, and are very expensive. In addition, you cannot delete entries off the cart - you have to reflash the entire cartridge if you want to make changes (though you can add more games to the end without reflashing if you have room). However, they function almost exactly like an actual GBA cartridge once flashed. NAND based carts use either built-in flash or removable storage like CF or SD cards, which gives you a lot more space for less money. However, they usually have a few features missing, like the real-time clock and advanced savegame management. I personally have both, because I bought the NOR-based one several years ago for the GBA and then bought a NAND-based one later for advanced usage on the DS.

Popular NOR-based cartridges are the Flash2Advance Ultra and the EZ-Flash line, among others. They are expensive though. A 1 Gigabit (128 Megabyte) F2AU cart cost me $125, though it's at about $100 now. At the time, I was sorely tempted by the $70 XROM, which was 512 Mbits (64 Mbytes), as it was a good deal. However, for GBA gaming, it serves its purpose very well. These carts usually connect to your computer via a linker, with one end with USB and the other end with a serial port that plugs into your GBA's link port. These linkers usually also allow you to dump official games (I think I'm allowed to mention that).

NAND-based media cards like CF and SD are too slow for GBA gaming by design, so NAND-based adapters copy the games into fast RAM and execute them from there. While this shortens the battery life, it gives you the advantage of using a CF or SD card to begin with, which is much more convenient, as you can freely add, delete, edit, and move files to and from the card using a card reader. This means you can't dump your own games though, but you can purchase a linker cable on the side for $15 or so if you want to do that.

Popular NAND-based devices are the Supercard and M3, but since you're going to be using it for GBA gaming mostly, I'd suggest the M3, as the Supercard has slower RAM that makes some games slow down or simply crash. Get the M3 Perfect, not Pro (the Pro has very little RAM and therefore supports only very small GBA binaries), and I'd suggest the miniSD version (not the same as Slim SD) if you don't want it to stick out of the GBA. While the M3 is fairly expensive, you end up paying much less for the same amount of storage, and you can always increase your storage capacity by buying another cheap miniSD card rather than buying a whole new $100 cart like you would have to with a NOR-based cart.

I would use NAND if I were you as it will save you a lot of money and Flash memory is really cheap. But I would also like to add that some of these carts can be illigal to import so I would check them first. just to be on the safe side I would get an M3/G6 or EZFlash.

Well, you guys have given more new information that I wasn't expecting to get.. If I got the M3 cart I would also have to get a miniSD card to go in it right? How then, do I back up the games that I own? The last I heard it is still legal to backup what you own. Once I got the game backed up, I can see then how you could use the M3 to restore the game if my original got damaged. This sounds like what I want but the original backup has me confused. thanks

Yes, you'd need both the M3 and a miniSD card. If you want to use it in a DS for launching DS code, you'll also need a NoPass device like the Passcard 3, but this is not needed for launching GBA code.

There is no way to use the M3 alone to backup games, but you can use one of those linker cables to do it. Something like http://linker4u.com/pp/item_detail.asp?itemID={AB02EC20-5BE6-4EE6-9EC9-E225FD3C0BB6} would work, as you could use the shareware FlashManager program to dump the games (the official PowerWriter software can dump games but only after it has linked up with the F2A Ultra cart in the first place, while FlashManager can skip this step). You would insert the game, start the software, turn on the GBA with Start and Select held, and then select what you want to do from the menu that appears on your PC screen.

The only place I can find a usb linker cable is at linker4u. Is that a safe site to make purchases from? Also, looking for a good miniSD I found this: Transcend 4GB mini SDHC Card

4G High Density .. you think this will work okay in the M3. (I've purchased and received my M3 by the way).. Thanks

I purchased a few items from Linker4U without trouble, though I've heard others that didn't have such good service. I think it mostly pertains to people ordering items listed as being in stock on the website only to find that they are sold out.

I'm not sure if the SDHC cards will work on an M3. I know they most likely won't work on a Supercard, but I'm not sure about the M3.

Okay, I'll stay away from the High Density/Capacity chip.

I can't find that linker cable in stock anywhere else, (except another Chinese site).

Any other sites? let me know..

Picked up a 1Gb miniSD today from Best Buy, about $30.00 plugged it into my usb attached reader. Installed M3 Game Manager V32B and began copying some of the freebe gba_homebrew games to the memory. Plugged it into the M3 and the M3 into my GBA and I was off and running. Need to get some music and movies to load next. Still looking form a linker cable.. thanks for the help.

For music, you can either use the M3's converters to convert the music to GBM audio, or you could use the GBA GSM Player by Tepples, in which you first convert to high-quality WAV and then put the wave files in a folder and hit go.bat to get the output "gsm.gba" file.
