You get a choice of like 18 different playable trainer skins and 80+ different starters
Then you learn that you can have all 6 of your party pokemon following you around on the overworld
Then you got the fact that you encounter pokemon via pokemon walking around in the grass, including visibly distinct shinies.
Oh and it has the full 1000+whatever pokedex so every different route has 20 pokemon walking around so as someone trying a Nuzlocke I'm just standing there struggling to decide which one to take
Oh and also since it's a romhack so I'm playing it on my 3DS
GBA era romhackers are something else
I think I actually have MegaMan X on mine. So what people do is they'll make a .CIA file (basically the equivalent of a rom) with the emulator built in.
IDK if this is allowed here, please if it's not let me know and I'll edit it out... But let's say you've installed your CFW on your 3DS. A step of that will be to install the file manager FBI.
You'll want to open FBI and go to the bottom option (it's install or download or something I don't have mine with me right now). Choose remote install, and from QR code.
Now on your phone or PC or whatever you can go to hshop.erista.me for example, here's their MegaMan X page and you'll scan that QR code. Couple seconds to minutes later (about 30-45 for the 1+gb giant 3ds games), you're playing your game!
Now I absolutely hate recommending reddit for really anything.. but their r/3dsqrcodes is a great resource for rom hacks. Almost all the bigger Pokemon ROM hacks are on there, I've got Super Mario that's been turned into The Call of Cthulhu...
Oh fuck yes!
Yeah man it's insanely easy to pirate the games you want on the 3DS lmao! Great console for data hoarding.
