I would us Tilemolester as it has a lot of benefits when hacking compared to YYCHR. Like
- bookmark what you find.
- Add pallets from ROM and save them too.
- Share resources.
- More codecs to view tiles as YYCHR.
Navigation is the same as YYCHR.
+ and - key: Shifting bits to align graphics pit plains.
arrow/tab: Navigating page.
CTRL+Arrow Key: Align Window size.
- When viewing sprites you like to view it row interleaved. This is because the nes uses 2x16 sprite assembly for OAM.
- Tile can be viewed normal. I am aware that this looks puzzling but most tilesets make enough sense to work with it.
- If you like to add a palette just look up the values of the colors in a emulator like Mesen or FCEUX and search the ROM for that value.
Palettes are mostly stored in a table so you find multiple palettes after earch other. Add the offset under Tab: Palette>ImportFromFile>ThisFile
If you like to arrange it you probably need tools like pyxeledit or Pro Motion NG what are tools for graphic editing and tile arrangment.
You could also use Tiled if you just like to arrange tiles and edit graphics elsewhere (probably a poor choice for this task).
I would recommend Pyxeledit:https://www.pyxeledit.com/
As it was worth the 10 bugs for me many times. I like that it is small and just has the stuff I need. Read try Demo and decide yourself if you like to have it too. It is not needed for the task.
I forget the topic and to mention how to share your resources haha.. sry
Well TM has a resource folder and it does save the bookmarks with the same name as the ROM you work on. Just copy my files into your resource folder and rename the ROM or the XML file. You said you use pal version and I named that one Legend of Zelda, The (E) (PRG1) [!]. (may be you did not use revision A and you need to add things yourself..) Not really worth sharing as I only added one palette and the picture I worked on ^^ Also added pyxel edit file for fast editing if you have it.https://www.dropbox.com/s/mt278c080q5nney/Zelda%20Pal%20Revision%20A%20Resources.zip?dl=0
