SNEmulDS v0.5 beta released

[Mooney]

SNES emulator for NDS

This version aims to improve in sound and graphics. As the emulation becomes more and more complex, it is more and more difficult to add new features without breaking the emulation overall, so some new feature will not be enabled by default for all games. The configuration file select which features are enabled or not, and becomes very important (so don’t forget to put it in the root directory!).

 

I tried very hard to improve sound, and i succeeded to get much better musics in some games, but there may still some “pops” or “cracks” sometimes, and the sound can slowdown or goes mad in some rare circumtances (the ARM7 seems not powerful enough).

 

A new menu has been added : the GFX config menu, this menu offer a simple way to change the GFX behaviour in real time. The emulation is not stopped like in the options menu, you can enable/disable several features and see which ones are better for the game. (See README for more informations)

Here is the list of changes

 

* Changed the Sound timers, now the timers should be a bit more accurate and removed the timers hacks

* Moved back the Sound RAM in the fast ARM7 RAM, removed unused code from ARM7 codes

* Now support sprite address change during frame (limited to two addresses by frame), this makes Ogre Battle much more playable

* Left handed people can now enjoy the SNES mouse option (right buttons can be used like left joypad).

* Options can now be saved in configuration file

* New SNES config menu

* Fixed some bugs

 

Optionnal feature (enabled by configuration file):

 

* Added sound synchronisation fixes, this is a set of flags that make ARM9 slowdown or make ARM9 wait for the ARM7. Those options make Square games (and other games) sound much better, but also break sound in other games. So this option is available through the configuration file. I only changed for the configuraiton file for Chrono Trigger, SOM1 and FFVI. You will have to modify the configuration and test the options for other games.

* Added priority per tile for BG3, by detecting if there are more low or high priority per tile at each line (see README)

* Added priority per tile for BG1 and BG2, by using the fourth DS layer. Low priority tiles go to fourth layer, and high priority per tiles (this idea was taken from SNESAdvance).

* Sprites priorities can now be changed. See configuraiton file for more informations. The default is 1123 but 1223 makes some games look better (like Castlevania IV first level for instance)
