As promised, here's the thread where I asked stupid questions: OK, so I have my M3, and successfully (thanks TheSpade) flashed without bricking my Lite. I'm current with the new releases (by the way, what utility can I use to keep track of them?). Now there's a bunch of stuff I need to understand. What does the M3 game manager do, exactly? I think it copies the ROM, and patches it or not according to the options... and creates an initial save file? is that needed? I'm not sure I understand all the options and don't know where to read abou them (the "help" file really doesn't). For DS roms, the manager software lets me choose if I want a software reset (why wouldn't I always want it?), if I want to trim the rom (again, why not always do it?) and read method/DMA speed (what are these and which should I choose?). If I understand correctly, whenever the game thinks it's saving to cart, it's actually saving to the M3's SRAM - does that sound about right? Also, what happens to SRAM when you turn the unit off? Is it possible to lose the save, and how I can I make sure it doesn't happen to me? Does all this rely on naming the ROM to a certain filename, so that the program knows what patch to apply to it? For GBA, the game manager software lets me specify a GBA patch method (SW/HW+SW/HW) - what's that? The other option is whether I want a realtime save. * Why would I ever not want realtime saves? * Do these go exactly where the non-realtime saves go? I mean, are these the same type of files, and the only difference is when it happens? * Again, can I do anything wrong and think a game saves but find out later it didn't? The only time I lost saves was with the dreamcast - it had two types of memory card, VMU(memory card+tiny mono display) and non-VMU, and one capcom title (resident evil 2, or was it 3?) decided any card without a display was faulty and should be reformatted - without asking first, of course. I really don't want to go through that again - ever. (By the way, I don't have my DS now anyway - a friend comandeered it once he found out I had NSMB. Should get it back in a couple of days).
