You should look at rxTools, which looks like it can boot into emuNAND as long as the system firmware is 9.2.
There's also MT Card's emuNAND, but I think that needs firmware 4.X, which may require a downgrade (which is a little dangerous).
Setting up emuNAND with either, and updating emuNAND should let you still use the eShop and the browser exploits, just make sure it's the emuNAND being updated (only done through system settings, ensuring the proper prefix in front of the system version, GW3D, MT, or RX-E.)
