I am using CHR Ram, indeed, which was why this was funky, and as soon as he noticed the chr bank switching, i knew right where to look (since I'm not doing that! haha).

Using INL's *mapper 30*...essentially an UnRom with 512.

Brian Parker for the win. This one was hiding in plain sight. It took him 4 minutes to find with just the ROM, and took me three to fix once I knew *where* the problem was. Found it instantly. And it was certainly user error. I'll tell you how the problem manifested for anyone who is interested. My ...

Thanks - I did try something similar to this...from my understanding it would've had essentially the same effect... I set up a breakpoint on writes to 2000-2007 from the start. Just let it catch the writes during the screen loading nonsense (skipped passed them) and then ran it during normal game pl...

Punch - yes, and info will be forthcoming about that when the game is done...that's our first priority. Honestly, some info about it will likely be hitting as early as next week. If you're unfamiliar with the project - http://www.thenew8bitheroes.com/ a ton of people here are featured and were integ...

Dustmop - that occurred to me too, though I can pretty definitely rule it out (the 16 thing). It is sort of variable depending on objects being loaded. So for instance, the first time this happened, i'd loaded the monsters first, whereas this time, the NPCs...i think it manifested on the 18th object...

This is sort of what I thought too - but if you watch the video, and how it doesn't happen with object, but does with the copy, and the copy copy, and does with the copy copy copy, but NOT with the copy copy copy copy of the object....it tends to lend more credence that it is in some way memory rela...

Ok - so I'm working up a theory here based on things I think I once saw somewhere. I have a graphic glitch that I can not explain. Certain objects are drawn accompanied by bizarre glitched out horizontal lines. This seems to have nothing to do with the object data itself, as duplicates of the object...

I'll keep an eye, but this is happening when screen is off - fade out -> screen off -> new screen load (including this function) -> screen on -> fade up.

Huh - thanks for the suggestions. Oddly enough, it was the matter of rendering not being turned off...strange. Tracing it through, it SHOULD be off at this point, but sure enough when I sandwiched a write between a render off - on, worked fine. This problem didn't manifest when using the first namet...

So this is a strange one... I'm using horizontal mirroring. Originally, I'd used my main nametable (at $2000) pretty much exclusively. I've since decided to use the nametable at $2800 to handle my sub-menu so that I can easily preserve things like destructable terrain on a screen (don't have to relo...

Thanks for checking in Koitsu - yeah, everything is definitely pushed and pulled for the NMI. And every time I *think* I worked this issue out, it manifests again. This has not been an issue at all to this point, and it manifests at the strangest places. Whenever it does manifest, it seems that when...

Using ASM6 with FCEUX. Generally, I'll do a write to, say, $07ff of where I think the problem value my be, and then in debugger check writes to that address. This method, and just using JMP RESET to see if portions of code are being reached, has managed to get me pretty far. This one still stumps me...

Thanks - I thought about the stack, but I'm not touching it in those instances...literally, if I have LDA temp followed by LDA temp it crashes. Temp isn't using that variable space, it's on the zero page. Checking in FCEUX, nothing is showing up in the stack register. Now, it is completely possible ...

I have no idea what could be causing this as an issue. I've gone back to futz with my nametable loading routine just a bit. Everything is working as I'd expect; essentially, I'm making a few case scenarios where of a flag is set, load this, if not, load that sort of thing. Standard. Got the case don...
