Which version supports touchscreen in emulators?

[Oranj]

I want to use an emulator for debugging but with latest libnds touchscreen doesn't work on any!
But there was a version of libnds that didn't have this problem since there are homebrews that work properly in emlators.
Emulators I tried: iDeaS, DeSmuME.
NO$GBA works but it doesn't support FAT which I also need.
By doesn't work I mean touchRead(&touchXY) returns zeroes.

The most recent release announcements for libnds include a link to a working DeSmuME build. http://devkitpro.org/viewtopic.php?f=13&t=2389

This is an emulator problem, not a libnds problem. Please report the issue to the emulator authors and do not attempt to use old versions of libnds to avoid emulator bugs.

If you're using FAT to load files you could consider using nitroFS via libfilesystem instead. The latest builds work just fine with DeSmuME.

Iirc, this problem was due to an incomplete support of FIFO in the older versions of desmume and an increased use of FIFO in later versions of libnds. Correct ?

Not paticularly no, it was incomplete emulation of FIFO related interrupts. You're about 2 or 3 years behind the times :p

Problem solved, works fine in latest desmume svn3904
