MacOsX Build of Desmume

Hi,

I made a new build of Desmume for MacOsX, with the latest CVS. Unfortunately, the Intel build does'nt work (I do not have any Intel Mac). So, for Intel mac, launch Desmume under Rosetta.

Re: MacOsX Build of Desmume

Hi,

Bad news... My latest build, from the CVS sources doesn't run any commercial ROM, even those marqued as "playable" in the compatibility list. I tried with WarioWare Touched.

But it can run my little "homebrew démo"...

It was working better before. Any help ?

Re: MacOsX Build of Desmume

Define "before" with a CVS revision time, else it's quite futile to search

Re: MacOsX Build of Desmume

Well, it was working for some ROM the last time I build Desmume (circa, 02/2008). Since, some change was made, and I cannot play any ROM, except the little demo I made.

It seems that the CPU emulator hang. Nothing happen, except a blank screen.

Re: MacOsX Build of Desmume

Could you please check out a few older CVS versions and be a bit more exact. Remember I can't debug neither "see" that bug, so try to be 100% concise about which commit is the culprit smile

Re: MacOsX Build of Desmume

The culprit is the revision 1.36 of NDSSystem.c, 1.35 is working fine.

Re: MacOsX Build of Desmume

Oh, thanks for the patch. I wrote the problematic piece of code, but, obviously, I didn't remember to use the endian safe memory functions tongue I've just committed it to the official CVS

Re: MacOsX Build of Desmume

Yesss !!! It's working, now. Nearly usable on my iBook G4 1.33 Mhz wink

I will try some ROM, from the compatibility list.

Re: MacOsX Build of Desmume

I guess it's 1.33 Ghz and not Mhz, else you've got a singular piece of hardware there tongue

Re: MacOsX Build of Desmume

wink I didn't tried to build Desmume on my Apple IIgs.

We still experience some graphical glitch, like this on Warioware on the PPC build:

More over, I will see how I can enable Opengl with the Cocoa build.

Re: MacOsX Build of Desmume

Well, probably some stuff isn't still endianess safe. If some active developer with a Mac could work on that, we'd probably get those bugs fixed quite easily: if I had access to any type of Mac hardware, I would do myself tongue

If I knew, I'd fix it myself. It's just a matter of looking for memory read/writes that don't use the endian safe functions, which is quite a lot of work considering desmume's size.

Re: MacOsX Build of Desmume

I'm looking for every MMU_WRITE32 to see if there an other example of what Phazz found, but cannot find  the same  thing.

Does thing like that:
MMU_write32(1, 0x00, 0xE25EF002);
MMU_write32(1, dst, T1ReadLong(MMU.CART_ROM, src));
MMU_write8(cpu->proc_ID, 0x4000300+cpu->proc_ID, cpu->R[0]);

need LE_TO_LOCAL ?

Re: MacOsX Build of Desmume

No, it's a matter of direct memory reading or writing, there's none there.

I fixed the particular Wario sprites problem, but there is a lot of discoloration, so I'm working on that.
