[Enhancement] Allow patching romfs for DLC #1887

Open DullPointer opened 1 year ago

Apologies if there is an existing story for this, but I couldn't find it. I discovered this was a known, current limitation from the wiki, after trying unsuccessfully to patch some DLC myself. Could DLC patching be implemented in a future release please?

"Note: DLC patching and HANS-style romfs binary files (instead of a folder) are not supported at this time."

Thanks for all the great work.

I've been trying to figure this out recently. From what I've read, official updates/DLC from the e-Shop could have their own files in the ROMFS, and it was entirely up to the game for how to handle this. I can imagine this makes patching on top of updates harder to implement.

Hopefully someone much smarter than me can figure out how to support dlc patching, but in the meantime, I've ended up just manually modifying the ROMFS of an updated game.
