Whee ?

Wii hacked (using bannerbomb) ! This is actually old news, but my laptop’s hdd died so it got delayed :p.
Also, i recieved the beagleboard from ZeZu and got Ångström working nicely.

So expect wii and arm updates soon ;)

Finaly some progress !

May 4th, 2009

After many many many many many months of inactivity i finaly started some real work on the dynarec.It now features a basic IL with a working decoder frontend and backends for x86/arm/mips-allegrex.Work is currently done to port the code to Wii/ps3/ps2 ( only if libstdc++ worked …)/xbox.Anyway i don’t feel like writing atm maby i’l edit this post later

*edit #1*

Note that the arm videos are much older than the psp, the arm rec misses MANY opcodes at that point.When ZeZu brings arm on par/i get the beagleboard he mailed speeds should be ~ 3x of what psp gets :)

*edit #2*

To give some PSP numbers, bios (menu) is up from ~ 1.5 fps to ~9, Doa2 ingame from ~0.8 to ~4.5 , PoP3d from ~ 1.2 to ~9.Only 4x more to get PoP fullspeed :p

*edit #3*
Added more PSP videos !

Q: What the heck is a “beagle board”?
A: “The BeagleBoard is an ultra-low cost, high performance, low power OMAP3 based platform”.Its a ‘devkit’ for omap3(Arm Cortex-A8, PowerVR SGX) and it is/will be very similar with next generation of non intel based mobile devices.More on http://beagleboard.org.Pandora is a very similar target to BeagleBoard (and will be mostly compatible).

Forgot to say, if someone could donate a copy of The Legend of Zelda: Twilight Princess (PAL) i’l be really happy.I spent all of this month’s money to buy the wii and developing with dolphin sucks ><.Anyone interested can email me (drkiiraziel@gmail.com) or come over on #nullDC @EFnet.Keep in mind that i live in Greece and shipping to here can be quite expensive from outside EU.

Clarifications about nullDC/psp

July 29th, 2008

nullDC/psp will only be for psp lite. The old(’fat’) psp just doesnt have the ram space needed, nothing i can do about that.

The current speeds are very low, but that is expected. There is no dynarec, no optimisation, not even a single mips assembly line on the current source. Most of the current code (everything, apart from 3d rendering) is based on the pc version of nullDC, and most of this code will be replaced. So yeah, IT WILL TAKE QUITE SOME TIME BEFORE THE PROJECT IS ANYTHING NEAR USEABLE.

The current speed (as stated by the on screen couters) is around 10%. THIS IS WRONG, IT IS ACTUALY LOWER. The interpreter runs underclocked (to make the speed bearable). This also happens on the pc build of nullDC when using interpreter (for the same reasons). The rps field (renders per second) is accurate.

After the code is cleaned up/rewriten there are plans to port to pandora ( www.openpandora.org, realy cool stuff ) and possibly other consoles (wii seems like a nice target, ps3 if theres a way to get 3D access). ALL THIS MAY(OR MAY NOT) COME AFTER THE CODE IS REWRITEN, SO DONT ASK ABOUT IT NOW(you’l just waste your time, realy). The code will be open sourced as soon as it gets stable.

While i think it is possible to get fullspeed on psp it is quite likely that i will be proven wrong. I CAN NOT MAKE ANY PROMISSES ABOUT THE SPEED, I ONLY PROMISE I WILL TRY  TO GET IT FAST.

If you somehow think this project is wasted time, then dont waste any more commenting/thinking about it. My time is .. mine, i can do whatever i want with it. Seriusly, if you want to say something bad just save your time, it wont realy change anything ;) .

 

There, i hope this clears up some things. If for some reason you’re still confused read over the bold parts, that will help :p

nullDC/PSP update #2++

July 27th, 2008

So yeah, some fixes here and there, gdrom code added, gdrom selection and ..

Too bad the game crashes with some invalid stuff on TA ingame … i realy need to use *stable* versions while porting, and not experimental drkpvr stuff :p

PS. Oh yeah, the game is DOA2LE

*edit*

Aparently SOTB works fine too :)

*edit #2*

Fixed the ta problems, doa2le ingame works :)

nullDC for psp update

July 26th, 2008

I finaly got the psp port/rewrite of nullDC running bios with texturing!

Many thanks to PSPdemon for recording and uploading the video :)

First Post !

June 23rd, 2007

So after a long time i got around setting up a blog.I’l post coding related stuff mostly, usualy about emulators/compilers :) .Lets see how this turns out…
