emus3ds VS open_agb_firm

Here's the readme for TemperPCE.

Also, I'll add to your list. There's also PicoDrive for SMS/GG/Genesis/MD and TemperPCE for TurboGrafx-16/PC Engine, both by the same dev, bubble2k16.

It can be done. Have you already followed the 3ds hacking guide to install Luma3ds? If so, I believe you can simply just use a homebrew emulator for Mother 1 and 2 (Virtuanes and Snes9x3ds). You can also use NSUI to essentially install them as games to the home screen. Ask r/3dshacks if you need help or have any questions.

CFW also allows you to have better GBA (open_agb_firm, VC injects, or mGBA) and NES (VirtuaNES) emulation and everything else is possible with CFW too, an R4 isn't really needed on 3DS unless you want to play one of the few games that don't work with TWiLight Menu++.

Don't forget about emulators! Especially if you have a "new" system - you can even play some (mostly 2D) PS1 games, and some N64 games on it, and everything older. On an "old" system you are more limited though - SNES games that use a SuperFX chip (such as SM RPG, Yoshi's Island, Star Fox, and some other ones) will run slow, but Genesis and 8-bit systems will run no problems. And you can run GBA games - on "new" you can even use the system's gyroscope for games like WarioWare Twisted or Yoshi Topsy-Turvy through mGBA, and on any system you can use injects or open_agb_firm - they both run games natively using the ARM7 CPU - the same one GBA uses, carried over into the DS, and it's still included in the 3DS.

Use open_agb_firm. It's a firm, so it's activated in the same way as GodMode9, hold START while turning on the 3DS. You should be able to download it via Universal Updater. open_agb_firm uses the 3DS hardware to give you the same experience as playing on a real GBA.

That depends on how you are running the game on your 3DS. The best way is with open_agb_firm, in which case you will probably need to convert it with https://exelotl.github.io/gba-eeprom-save-fix/ (as linked from https://github.com/profi200/open_agb_firm ).

If you're playing a GBA game, open_agb_firm or a VC inject are your best bets.

You could use open_agb_firm to play your GBA games instead.

Because unfortunately mGBA is a little bit laggy on the 3DS. It’s terrific for game boy and game boy color games, but I digress. You could use something like open agb firm which runs games using the 3DS’ built in gba hardware natively without any lag or slowdowns.
