What is .twl ?

Hello there. I am trying to recompile my homebrew with the latest devkitarm (r50, gcc-8.2.0)/libnds(1.7.3.1) I downloaded and I was surprised most of my tools inflated over 4MiB. My investigations point to a .twl section that has a physical address of 0x2400000 and gets effectively mapped at 0x400xx...

Re: devkitARM release 50

I note that devkitARM_r50 contains a curious warning message about use of __sync_synchronize(). It's a gcc built-in memory barrier which only emits a call to __sync_synchronize on platforms which don't have memory barrier instructions. In your case you can compile your code with -fno-threadsafe-sta...

Re: devkitARM release 50

I note that devkitARM_r50 contains a curious warning message about use of __sync_synchronize(). Do you know of any context that lead to that line to be present? Is there any multi-thread-capable platform that makes it meaningful ? Would I be safe for NDS to redefine __sync_synchronize() as an empty ...

Re: devkitARM release 47

ah ? apparently, this could be a candidate. (found through the huge "instructions for installing the Tools" link on the home page, if you ask ^^")

Installer link

Hmm… The link to sourceforge seems to send me back at the forums home page.

Could it be possible to update the link towards the appropriate file in https://github.com/devkitPro, or has the .Exe installer/updated disappeared during the switch to pacman ?

Looks like the performance are now comparable to the one in the "good old" implementation. Great job.

I've got some time to give that performance issue a look again. I'll grab the libfat 1.0.9 and keep you updated.
(looks like I'll also check the "notify new posts" box ^^")

Re: Which version supports touchscreen in emulators?

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 ?

Re: Faster writes for libFAT 1.0.7

There are also some changes which will probably make your patch fail. I suppose you refer to the "GEKKO" modification that decides whether a "write-through" of a whole set of sector should leave a copy in the cache when there was no previous entry in the cache for them. I will ensure that I don't g...
