Just came across this this morning and it's something the whole community should know. While I do not know the EXACT number, I have found out that there is indeed a limit to how many titles can be installed on either the O3DS OR the N3DS. I found some Genesis injects off another site and decided to install them to my N3DS. When I went to the Home menu to organize and then to try the new Smash DLC, I noticed that a lot of my CIA games have disappeared. Rebooted, updated to 3.4.1(even though it's more of an O3DS update anyway), and the games were still missing. Searched for answers and a user here suggested there might be a limit of 333 as far as installable titles. So, I deleted the Genesis injects and a few other games that I didn't really play, got kicked back to SysNAND, went BACK into Gateway, and low and behold, the missing games were back as gift wrapped packages. I unwrapped them and put them back in their proper places and turned the system off. Rebooted back to Gateway, played one of the games involved in that whole mess, and my save data was still there(thank GOD as I have 83 stickers in Disney's Magical World and all of the eShop and QR code DLC). So, the game isn't GONE per say, the icon just disappears if you have too many titles installed. I have a 64GB Sandisk Ultra MicroSD and a lot of the games on there are NES, Game Boy, Game Boy Color, and Game Gear injects, so I was definitely at that limit. Hopefully, someone can figure out how to bypass that and make it so that you can have MORE titles on the ticket, especially since the menu is clean on mine since I organize into folders. But, I'm here to PERSONALLY confirm that there IS a limit on how many CIA's you can install and that will show up on the Home menu whether in a folder or not. Also, since RXTools and Pasta's EmuNAND is based on Gateway's, we should definitely have those users look into it as well as I read a LOT of people's games disappearing from those firmwares. On a side note, can anyone recommend a good NES and GB/GBC emulator with save states that I can use on Gateway to clear some of these now seemingly precious slots?
