cs-topics VS CTRMap

Here you go, here are starting points: https://teachyourselfcs.com/ https://learncodethehardway.org/ https://projecteuler.net/ https://exercism.org/ https://www.freecodecamp.org/

And since we’re here: https://teachyourselfcs.com

Doesn't change my answer. Any engineering/math/CS degree looks good on a resume. You're still responsible for the knowledge outlined at teachyourselfcs.com, whether you pick that up from classes or your own self-study. Employers don't know the difference.

If you had a degree, but not in CS, then that's workable so long as you acquire the knowledge found at teachyourselfcs.com and build some nice personal projects to show off on your resume. It's easier just to do the CS degree.

https://teachyourselfcs.com is also good for self-learning what you would’ve learned in college.

If you want to look beyond programming proper, there's the field of Computer Science as a whole which goes well beyond programming. A great resource for computer science is https://teachyourselfcs.com/ if you prefer to stick with just programming, a great resource is https://www.theodinproject.com/ but there's obviously a lot more to both programming and computer science than what is covered by these two websites.

CTR Map - a map and NPC editor (basically the 3DS equivalent to Advance Map)

you should also consider if you want to make a 3DS hack. you wouldn't have to program pokemon-amie from scratch, since it's already in the game. basic functions of 3DS hacks are behind those of DS and GBA hacks, but there are mapping tools, and there are scripting tools as well, so... you probably have enough to actually make something in gen 6? it'll be more work than hacking for a different gen, but if you're willing to program a new feature from scratch in a DS game, you must be willing to put in more work than the average romhacker anyway :p
