[PC Emulator] No$GBA Emulator

Updated my gba/nds/dsi emulator/debugger: http://problemkaputt.de/gba.htm
It's just a bunch of small details/bugfixes.
The sd/mmc/i2c related ones might be useful for developing & testing new DSi exploits.

23 Jul 2017 - version 2.8f

- nds/3d/emu: matrix stack in mode1 behaves like mode2 (fixes light directions)

Strangely nocash posted on gbatemp, but not on ngemu where he normally dose.Maybe not a lot going on at ngemu..

He's probably no longer active there?

Replying to #3

maybe his last post was nocash, May 26, 2016.

That might explain it. We got members like Jimmsu who hasn't return in years.
