Yes let me know what your email is via PM and I'll zip the stuff and send it over. Karsten, why would you prefer the cart? Just curious. For my uses, I always found the traditional backup device like the GDSF to be a much better fit. Even if your Flash ROM can be Flashed 10,000+ times, it still takes alot longer to change or load up a game than it does for me to click twice on my PC to send a ROM. But ya, for the sake of discussion make your argument.
it's faster than floppy IMHO, "cleaner" in not needing YET ANOTHER power adapter, easier to bring along to friends. no need to save to floppy disc during you RPG sessions. for me space/cable around is a really great factor.
I didn't think about the power adapter though I did think about the portability of taking it to another system is nice. As for the floppy, yes it's faster than loading from a floppy and more convient than having to save to a floppy, though the FlashCart can only support one SRAM game at a time as I remember reading. Meanwhile the disk can save nearly an unlimited amount. Not to mention if you leave a GDSF plugged in it will retain the SRAM. But my main point would be that since most people have a PC at their fingertips, you'll want to use the Parallel Port on the backup unit which sends as fast as the Flash Cart's base as they are both parallel but probably faster since I'm sure the flashing protocal is slower than just loading DRAM. It's very nice, but you're right you have to route a Parallel cable from your PC to the back of your system then. Not exactly portable, unless you use Floppy Disks which are slow. ='( So each certainly have their perks and I certainly wouldn't mind having both. But for now it's just the GDSF7 which I'm quite happy with.
I have an old backup unit for my SNES. The design makes it resemble a real SNES(PAL)/SFC peripheral, it does not require any additional power for the floppy drive (draws from the system itself) and it maintains the SRAM while being turned off (only deletes it if you load a new game with SRAM support). Supports DSP through donor cart, but does not support more than 16mbits of memory (detects higher numbers but is unable to handle it when loading stuff to it. Same goes for dumping, dumping is limited to memory size) It's a clone or something of a Pro Fighter or something. There is someone mentioning one here, but that one seems to have a different BIOS than mine, as his says Pro Fighter on while mine says Hyper Effect Pro. 9 in the BIOS menu. (Different production run or a re-flash, I guess). Added a bit more than planned here... Originally just wanted to add that there are backup units that does not require any additional AC adapter(s).
