So you have to go into sysNAND each time you want to play DSiWare? That sounds annoying, I can just play them from the home menu.
So you either leave your DSTwo inserted all the time and have your battery drain really fast, or have to take it in and out when you want to play a GBA game? That sounds annoying, I can just play them from the home menu.
I don't know what this means.
That sounds annoying - I don't need scripts. If you have Gateway it is different - if you don't mind going through all that trouble just for the cheat menu. But that is the only upside. It would be ridiculous to have an emuNAND if you weren't using Gateway's cheats. I have a Gateway and was using it to cheat on Badge Arcade when it came out, but stopped using it when Gateway didn't update for the latest firmware for too long.
Considering I boot into SysNAND by default most of the time, why is having to do so a big deal? Besides, it's not like there's that many great DSiWare titles.
Actually, I tend to prefer my GBA expansion pack on my DS Lite until I can get an ED GBA sometime. I'm not usually one to take the emu side on anything, but those injects just look awful.
My point was, if the NAND's just backed up on your card, you can't run it when you need it for something. You have to install it over your current one, and then your SysNAND is no longer on the latest version, could be missing titles if it's using a different ID, etc.
And there's one other really good reason to use GW. I have hundreds of ROMs, and I'm not going to waste my time converting most of them (just the ones with online features I might actually use), because there's no point. They play the same regardless. Besides, I don't have space for two copies of everything, and if I just keep the CIAs then they'll never work with my Sky+ again. And it's not annoying at all. You just have to sync after installing new titles and before you use the the other NAND. It's not like I install CIAs every day. Maybe once or twice a week. So, once a week, restart, tap left, tap home, select scripts, pick the "Synchronize Tickets" one, and done. Takes all of 5 seconds. It's nothing, especially compared to the alternative -- having to install the same games twice, and having them take twice as much space.
That's not even my only EmuNAND. I've got a second one on 9.2. Simply because it's the most exploitable system version ever. I've even got a Cubic Ninja CIA on there for running Ninjhax 1.1 still. I'm fully prepared for the fact there are some things Rosalina will just never run. Sure, there are CIAs for ctrHexenII and eDuke3D, but not Spectre3DS or 3DSCraft (not that I even play 3DSCraft, but Spectre's a Quake port by elhobbs in full stereoscopic 3D, and with music support).
And no one technically needs scripts. But they are handy. You can manage your activity log (thoroughly). That whole incognito thing where you backup your PTM and restore it later? Automated. And I've got a couple more that can wipe AL by itself or AL+PTM. We all know it has nothing to do with the bans, but I put it together anyway for those who obsess about such things. You can also sync the latest Luma update to CTRNAND. You can switch your chainloader's default payload, your current chainloader, even switch exploits (granted, there are already some scripts out there that let you switch between A9LH and B9S, but mine also swaps out the payloads and configuration files for you so you can still get into GM9, Decrypt9, etc.).
