Announcement: Cycle-accurate N64 development underway.
- Thread starter MarathonMan
- Start date
Yep, that's the idea, put the arcade pif in a n64 and the arcade cic in a cart that will be used by the backup/dev unit. I guess it should work fine.

I tested a handful of ROMs in Windows and never had a single issue after the last set of changes? Hmm... which ROMs are causing problems?
EDIT: You re-downloaded and replaced the ROM folder, right? That's where the fixes were, not in cen64-master...
EDIT2: Fixed another couple issues in the RSP. Found out that some ROMs are not booting or freezing after the intro because a corrupted audio list is sent to the RSP. The corrupted audio list destroys the contents of the RSP DMEM. The root cause of this is due to the fact that I don't properly implement the AI interface, so I guess I have to work on audio sooner than I wanted to... preliminary hacking with AI_LEN_REG permitted Super Mario 64 to boot, and kept the RSP alive for some other ROMs.

Yes, I downloaded and built from the source today. Your last commit was about 3 days ago, right?
Depending on where or in what kind of path I load cen64.exe in, I'm receiving mixed results whether I'm getting the 'Failed to load the ROM.' or not. I peeked in your source code and the code where you handle this is where the file directory is being mapped into memory. I'm also not sure if the filename is relevant, and whether quotes before and after the filename (when auto-complete a long filename using the tab key) have any influence how the file directory is mapped into memory.

Try changing the second argument from "r" to "rb" and see if that fixes it:
cen64/rom/Cart.c:119
Code:
if ((romFile = fopen(filename, "r")) == NULL) {
debug("Failed to open ROM image.");
return NULL;
}I don't thinkthe pathname needs to be escaped or anything fancy, but I could be wrong.

Compatibility 2013.8.25 - Test 2
Started out with a fresh clean ROM collection, all hopefully in the correct format. The dreaded 'Failed to load the ROM.' is gone now as far as I can see.
This gave me the opportunity to test more extensively.
Info:
- 'Running' means either it gives a black screen later on in the game, freezes or is unplayable due to too much corrupt graphics.
- 'in-game controller pak error' means I'm unable to progress any further into the game.
- 'in-game audio error' means I'm unable to progress any further into the game.
- Bolded titles are the last ones tested and might have been affected by changes.
Previously compatibility tests:
Compatibility 2013.8.21 - Test 1

Hmm... I don't see anything that stands out in that list (trying to look to see if all the ones that don't boot share a common ucode or something). Thanks again for doing this, and glad to hear it's working for you now.
I (think) I found a LWL/LWR/SWL/SWR bug last night and fixed it. These opcodes are frequently uesd by memcpy, so I'm not sure how it was stable before this.
EDIT: Neat, a few games that were not working from the list above are now fully functional.

Question regarding multi-threaded performance - just how much of a performance difference is there if you force CEN64 to only use 2 threads VS using 4 threads?

Oh, the multi-threaded thing isn't implemented at all yet? Well then, don't I look like a noodle?

Using MY software-renderer that angrylion optimized and fixed a few bugs in, you mean.

First of all, who are you? Second, if you want to be pissed, you should be so with Angrylion, he is the one who claims the RDP emulator to be his. MarathonMan only implemented it "as-is", there's no reason to attack him.

Nein.
He's "MooglyGuy" of MESS and (after looking through things) is indeed the original author of the plugin. He's definitely up there in the rankings of people who can be thanked for their contributions to N64 emulation in general and has assisted me in times of need before.
Consider this my public apology for referring to it as angrylion's; in reality, MooglyGuy/JustDesserts wrote the original plugin , to which angrylion has provided bugfixes. I've only seen it referred to as angrylion's plugin and only heard from angrylion, so I've assumed it was solely angrylion's creation up to this point in time. I understand how frustrating [EDIT: lack of recognizance] of others' works is, so I feel kinda bad here.

Sorry, I just get pissed when other people get pissed. Anyway, thanks for the (a bit harsh) clarification.

Apologies if that seemed a bit harsh; it certainly wasn't my intention. I was more trying to clarify the fact that I goofed up.

I wasn't talking about you. I was refering to JustDesserts original post. "MY work, you mean" does sound a bit harsh.

Speaking of MooglyGuy / Just Desserts, here we have two of his N64 test ROMs running:
(Unfortunately, I don't have any input controls when running these)
I wonder if there are more useful N64 testing ROMs out there so we can also test cen64 next to demos and commercial games.
PS: I do think Ville Linde was if not the first person with N64 development news on MAME/MESS.
