(WIP) Nintendo 64 EMULATOR to XBOX360 Progress Report - 模擬器

2011.06.29

It's alive !

Sorry for the lack of updates, I was busy with other stuff for some
months.

As you can see on my github,
( https://github.com/gligli/libxenon/commits/master )
, I think libXenon has improved a lot lately, with lots of stuff added
from Xell (NAND access, lwip & network code,...), a new ELF loader, a
unified ATA driver (that can access both HDD and DVD), the return of
opendir/readdir/... functions and many bug fixes and smaller
improvements in almost all drivers.

The reason for many of those changes is to be able to make most of Xell
a regular libXenon app: Xell would be splitted into 2 stages, one stage
which recovers from exploit and then decompresses and launches a second
stage, which is a libXenon ELF. To maintain backwards compatibility,
both stages would have to fit in the 256KB limit for a Xell binary.

Last but not least, I'm working on mupen64-360, my Wii64 port these
days, I already added sound and done some optimisations to try to get
more speed.

I multithreaded a good part of sound processing so it's done almost
for free, and in fact anything that isn't multithreaded (RSP emulation)
was already running in my version from january. I might be able to
multithread RSP too, it would probably give a nice speed boost :)

I also redone the port of the Wii64 dynarec, I did my first port from
the ps3 branch and it seems it wasn't up to date with the trunk
speed-wise. Now it's using Wii64 1.1 code. I also changed the way
stores were handled in the dynarec, trying to generate more code and
rely less on a (slow) generic C function to do the job.

By the way, source code is now available on my github (
https://github.com/gligli/mupen64-360 ). Anybody that can compile it can
try it, but please don't distribute binaries ! It's not a good idea at
all to release unofficial versions of a work in progess of someone else
code so I hope You can be responsible on this.

Here's a new video showing the progress on Mario64, jerkiness is due to
the video capture card, trust me that game runs smooth :)
