Hacking Homebrew How's the support for homebrew apps after Switch fw 19.0.x and 20.0.x? Is fw 19 safe for heavy modding and use of overlays?

I am currently on firmware 17.0 and everything is fine. As the fragile being made of flesh and bone that I am, I want to update at least to 19.0 (or 20.0 if there's no escape) so I can play Pokémon ZA without the frame drops and flickering.

However, there's a change that deeply concerns me:

Please note: As a result of changes made to nintendo's software in 20.0.0, there is roughly 10MB less memory available for custom system modules.We can only steal a maximum of 14MB from the applet pool, down from 40MB.

• To compensate for this, ams.mitm's heap usage has been reduced by 20MB.
  • To facilitate this, a new helper module (memlet) was added, so that memory may be temporarily stolen during the romfs building process.
  • Hopefully, this results in relatively little breakage, however it is possible that user mods which replace extremely large numbers of files in The Legend of Zelda: Tears of the Kingdom may no longer function.

How's the community and homebrew devs dealing with this change? I use cheats, mods and Ultrahand overlays (Edizon, CaptureSight, etc) a lot, and I'd hate to have it all stop working due to memory constraints or the dev not updating the app.

For example, would a mod such as this one for Pokémon SwSh run fine? Did the memory change affect it?

Did any of you have to stop using/to uninstall any homebrew app after these changes? Which firmware would you recommend for me?

AFAIK, the issue with battery drain already has a fix, and there's this listing slowdown issue that hopefully is not that harmful (was it fixed already?).

Anything else I should know before considering an update?

If you want to play Pokemon Legends ZA you needs to be on firmware 20.3.0, firmware 20.x.x only 14MB memory, depending what sysmodules you are running you might run into problem running pokemon games while sysmodules are running. In addition the listing slowdown you mentioned, there is a battery draining problem that can be fixed with a config file.

Can be worked around with a config file. Fixing it involves recreating the emuMMC from an updated system.

Things are not looking so good lol
If anyone who plays using mods wants to share their experience here, I'd appreciate!

I'm on 19.0.1 firmware and am playing PLZA with the update fine. Don't have any issues with my modded TOTK or Skyrim either. I can't load Silksong or Hades II though, so those definitely need a firmware update to run. Unfortunately, don't know what the experience is like on 20 and up. Kind of in the same boat as you there lol
