themriron2 / desmume-psp

A Nintendo DS emulator for PlayStation Portable.

DeSmuME PSP

DeSmuME PSP is a port of modern stable DeSmuME based on the initial port by HCFcoder. It is completely unoptimised in its current state, but we hope to fix this and get games running respectably.

The plan, as described in the 2020 PSP Homebrew Dev Conference, 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. This will hopefully change in the near future.

Any questions, or want to talk to the devs? Come and talk to us on our discord server if you're interested!

desmume-psp's Issues

GPU acceleration

Currently, all rendering is done by the CPU in software. We want to offload this to the GPU as much as possible.

Crashes

The current DSonPSP code crashes, would be appreciated if someone can help me figure out why.

Integrating gPSP ARM7 code

Currently the ARM7 is being handled by the main CPU in software alongside everything else. We should replace the interpreter for ARM7 with Exophase's code. Ideally, we would want the ARM7 code running on the Media Engine and the ARM9 code running on the main CPU.

how do i build it?

well, i want to get a up-to-date experience on this emulator, but the only compiled release has 50 commits, the source has 72 commits, so i will not get the same experience, so i want to ask, how do i build the source code? thanks ^^
