It hasn't even been a week since Archeide rolled out SNEmulDS v0.4 Alpha, and yet he's back once again to bring us the v0.4 Beta release for his SNES emulator for the DS, SNEmulDS.

As you know, you're gonna need to patch this release with DLDI drivers because SNES games are loaded from SNES directory. And as with Archeide's other SNEmulDS releases, this version also packs in tons of changes and fixes, the full list of which you can check out below.

Changelog:

* Fixed the broken BREAK and COP instructions
* Fixed the ROM write protection by using the protection unit of the ARM9 (thanks to bubble2k for pointing me that)
* Fixed the Emulation flag at startup (problem with DKC3)
* Stupid again, SNES’s RAM was not in the cached memory, speed up games (10-20%)
* Reduced memory consumption, now ROM memory is static (no more malloced), should remove ROM overflow and RAM overwriten problems
* Added an experimental “line by line” engine (buggy, slow, unstable, uncomplete… maybe useful for a few games)
* Added a manual background priority selector (can be choosen in options or with START+LEFT+RIGHT+UP or START+LEFT+RIGHT+DOWN for automatic)
* Added another speed hack option : “Interrupt speed hacks” that should be better than “Full speed hacks” for some games. “Middle speed hacks” is now “Cycles speed hacks”

Installation and usage instructions are in the all-important readme file, so if this is your first time to try out SNEmulDS, we highly recommend you check it out.
