Anyone can point out:

1. What are the main good/recommended tools used to make romhacks without coding. To modify overworld, side views, etc...

2. Documentation about the Zelda II rom and learn the quirks and ways to hack in your own asm scripts. I'm able to understand technical docs, code, asm, etc... without much issue.

3. Any website more dedicated to Zelda II romhacking that romhacking.net?

Thanks in advance
