if I'm not wrong, R3k is a 5-stage pipeline (IF/ID/EX/MEM/WB). RA is read at ID stage and written at WB stage. The delay slot starts at ID stage of the branch-and-link instruction, so I guess RA in delay slot would be read BEFORE the branch-and-link instruction modifies it at its WB-stage. If...

@Notaz did you take into account the special case of "load delay-slot" (the instruction after a LW) in this emulator? Since ARI64's dynarec was for MIPS R4k and not for MIPS R3k, it may lead to some issues if some games are relying upon this special case.

From what I'm experiencing with developing PCSP (let us say it is a C++ version of JPCSP), I think multi-core is a real necessity to keep a good responsiveness even if it may be because I am taking a very different road regarding the usual way an emulator does. You'll need to run in parallel ...

He does know about Pandora since I already spoke with him about it. But I don't think he's interested as far as I remember.

And you need a PSP to : 1) dump your UMD into an ISO 2) decrypt modules as more and more games are encrypted and the only viable option is to make it through a real PSP.

recompiler3 is found to be used in all makefiles. recompiler4 appears not to be used. A small glimpse on its source shows it is a recompiler for a 64-bit MIPS (N64 ?) to ARM/X86/AMD64.

So the current situation is there are many ports based on an outdated source because Zodttd had never committed his real work to the public GIT and so all the forks cannot be updated ? PS: thanks

I noticed the latest psx4all source are unvailable (the GIT one is outdated and never has never been updated for a long time). Any success ?

you know what ? what DOES suck is your education. You may not understand about hardware and software requirements for ps2 emulation but your unlicked remarks are enough to call you a douchebag.

you can use "awk script" to retrieve the way it issues words to do the same with gcc : #define VADD16(dd1, dd0, ds1, ds0, dt1, dt0) __asm__ __volatile__ (".word (0xXXXXXXXX|%0|%1|%2|%3|%4|%5)", , "i"(DD0(dd0)), "i"(DD1(dd1)), "i"(DS0(ds0)), "i"(DS1(ds1), "i"(DT0(dt0)), "i"(DT1(dt1))) and...

Scary !

Just for info, psx4all uses recompiler and there is no such load delay slot handling in the recompiler. I didn't remember to handle it when I worked with Zodttd on GP2x version. And rereading its source, there is no such handling. Now, should it be worthy while handling this load delay slot to...

Reading SPIM code, their approach seems closer to the real implementation : the next instruction to run after a load delay slot is not necessarily the contiguous instruction in address. If the previous instruction of a load instruction is a branch/jump instruction so the next instruction having...

Hummm, let us say they need to do so. - Is it possible to find a branch instruction in the load delay slot ? if so, nighmare in sight for emulation, i agree. - Is it possible to find a load instruction in the load delay slot ? if so, what about the delay slot of the loading instruction ...

Sure but : All I was saying is : such a possibility to have such a N64 emulator on Wiz running decently is like dreaming of a beetle car trying to compete with F1 cars in a race.

As far as i saw in most PSX emulator source, there is no specific thing to do for a load delay slot. You seem to imply a load delay slot may work as a delay branch slot, which I'm not sure about it. Normally games will add a NOP just after if they need to read the target register of the load...

"the one-eyed are kings". There were a similar case in PSP scene with PSXP (ot whatever its name). Exophase does know what I mean. EDIT: ok, the other thread makes things quite clear : this guy (CR) is totally dumb and Devil64 a fake. Sorry to "up" this topic.

Do you think you can win a F1 race with a beetle car ?

that's an open source alternative for non-linux and proprietary firmwares in mp3 player/recorder. As an OS, it's pretty poor so there is no point for making a port to Pandora as it would never be much more capable than any linux port.

if i'm not wrong, the native OS is running in kernel mode - which means you can control everything, which may be very kewl. But i see uCos II sources and its Jz implementation : this latter is rather crappy. For instance, request_irq has an int return in its signature, but when the function...
