no$gba v2.8a released

May 3, 2015

Just released no$gba v2.8a. I've been planning to release updates more frequently, but as usually, it took three months to get everything polished, so here comes another new hardcore update - http://problemkaputt.de/gba.htm

There are some general GBA/NDS emulation fixes, and some GUI fixes. But the main focus is on DSi, especially on the eMMC filesystem. As with the previous DSi updates, the whole thing will probably appear to be totally useless to most people; most of the DSi hardware is documented & emulated, but the DSi memory initialization is still unknown, so the emulation won't work with commercial games. At it's best, it may be useful for stuff like debugging/developing homebrew DSi code.

Anyways, it's now possible to decrypt the DSi bootcode, so it should be possible to figure out the DSi memory initialization, and there's a quite good chance that the NEXT no$gba version will be actually able to run official DSi software.

Hey, I see he fixed the SWI CPUFastSet length Definitely an edge case, but I've seen it affect a couple of GBA games (Guilty Gear on the GBA iirc).
