1: it looks like your game still has a space.
probably because the loader kept the names in the titlecache file.
either disable the titlecache option and reboot, then reenable it (not sure if it will not re-use it with the space)
or edit the title manually in the loader to edit the titlecache file
or edit the titlecache manually
or delete the titlecache file (probably the easiest solution)
2: known issue.
I haven't look at it yet.
Other settings doesn't work with channels (like ocarina)
3: why would you like a different aspect ratio than your global one?
Currently, it's displayed is widescreen by default? it probably use the wii settings.
I would understand that VC would be better in 4:3, but WiiWare are designed and developed with widescreen format, no?
4: would be nice, but don't think it's that useful.
I'd prefer users to update the cheat txt for the game they want to play instead of flooding geckocodes with requests (DDOS?) for games that they won't even play.
Some users have less than 100 games and that's fine, others have 3000 games. that's not a good idea to me to add this feature.
It would even download cheats (or don't find any when you use that feature), which will need an update when you play a game because there were new codes posted since you downloaded them all.
You want to have the code ready when you open the ocarina menu, but it's automatically downloading it if missing when you open that menu. I don't see what's wrong here.
ocarina > (download) > see the cheat list.
There is a pack with all txt somewhere on gbatemp if you want all the games at once.

2014, but it's a start, not a lot of games had updates since then.
I think there's another thread with all cheats.
the Global ocarina option shouldn't be available, I don't understand users who set the global to ON while there's no code selected, or no cheat downloaded, or don't even know which code are available but WANT to cheats without knowing the game.
well, users are free to do what they want, but I just find it absurd to enable cheat for all games without selecting any cheats first.
What I would see as a better option is this:
When you go to ocarina menu and generate a gct, have the loader asks you if you want to enable the ocarina option/use that gct for that game if you don't want to go to the game settings to enable it manually.
