DeSmuME-PSP is an open-source experimental Nintendo DS emulator for PlayStation Portable DSonPSP source code by yoshihiro, which dev used to make some changes in this one. This project uses psplib, oslib mod V2 and MElib. Currently most of games are not playable, working on 10~15 fps.

Overview[edit]

DeSmuME PSP is a port of modern stable DeSmuME based on the initial port by HCFcoder. It is completely unoptimised in its current state.


The plan is to use a dynamic rebalancing system to emulate both the ARM9 and ARM7 processors on the main CPU and Media Engine, depending on which CPU has more resources available at any given point. It is hoped that with both the main CPU and ME working in tandem, many games will run well.


Currently, the port is very basic. Everything is done on the main CPU (including all graphics and rendering) so it is very slow, and SDL is used as an abstraction layer for many parts (eg. input) rather than native PSP calls.

Usage[edit]

Create a folder "DeSmuME" in /PSP/GAME/, so the structure is as follows: /PSP/GAME/DeSmuME/. Place the EBOOT.PBP in this folder, and within this folder create another folder called /ROMS/.


Place any legally obtained DS backups into this folder. Now you can simply boot DeSmuME from your PSP and the ROMs will show up automatically.

Old ports[edit]

DSonPSP: Proof of concept DS emulator for PSP by Yoshihiro. It was based on what is now ancient 2006/2007 Desmume code, and as a result it is very slow and most titles don't work very well. A few versions were released, up to beta 0.7 Kayliah Edition; this repository is based on the last publicly available source code, for 0.7 revision 7.

DeSmuME: Proof-of-concept port of the Nintendo DS emulator by SofiyaCat (aka NekoMimi)(2007). It has no menu, and will only open a rom named test.nds
