A new update has been released for DSVita , currently the only emulator in development to emulate the Nintendo DS console on the PlayStation Vita and PlayStation TV .

This new update introduces numerous improvements, including improved memory management precision by changing WRAM validation to only when necessary, fixing issues with games like WarioWare: Touched !.

Additionally, frequently used objects have been allocated to fixed addresses to optimize performance, and a CPU frequency display has been added to the top right of the screen.

Fixed interrupt behavior to address bugs in the Pokémon Black/White and Pokémon Black/White 2 games , and disabled self-modifying code checks for the ARM7 core by default.

The handling of multiple word transfers in fastmem mode has also been improved, with a slight optimization of the emulated CPU speed. The slow SWB instruction patch has been fixed, addressing issues with titles like Luminous Arc .

Finally, sound stretching has been implemented and previously missing HLE audio commands have been added, making the emulation experience smoother and compatible with an ever-increasing number of games.

Current state of the emulator

Current features

The emulator is capable of running some DS games, but it is still in a very early stage with many missing features and significant limitations:

3D rendering is very broken.
The 2D rendering is almost complete.
ARM7 HLE will not work with most games:
- Disable it if some games no longer launch, freeze, crash, or have problems.

Installation

Download the latest version of the file .vpk.
Install libshacccg.suprxfollowing a specific guide .
It is recommended that you overclock your PlayStation Vita console, as the default settings are not changed.

Always set the IRQ flag when waiting for an interrupt (fixes Pokémon Black/White 1 and 2 ).
Self-modifying code checks are disabled by default for the ARM7 core.
Implemented edge cases of multiple word transfers with fastmem mode.
