I think a feature like this could be useful as a cross reference when testing on real hardware.

I personally have some weird sprite issues when running my project on one of my machines. Being able to emulate various hardware failures would be a nice tool to track down where things are going wrong.

That looks like a lot of work! What's it for? Are you planning on making some sort of frankenstein all-consoles-in-the-same-box project?

Glad to see you managed to fix it and that nothing was broken! The solder pads to the PPU can be very fragile in my experience, at least if you desolder by hand without advanced tools like a Hakko.

Your famicom and NES PPU are interchangable (if not identical). I would very carefully desolder the famicom PPU and reinstall it with a 40 pin DIP socket to make sure it still works properly. Then I would try swapping it with the NES PPU as you already suggested, being very careful not to damage any...

Retro-access? You may have to look under the SNES section for a multi-out one.

Unfortunately the french NES rgb out is not the same as Nintendo's later consoles. I think the connector is mechanically the same as the FDS, unfortunately.

Very nice mod, but why didn't you use the existing rgb out instead of putting in that scart port? I live in sweden but bought a french nes just so that I wouldn't have to alter the case...

Well anyways, glad it worked out for you!

I also have a PAL NES with the NESRGB installed and I remember not having a 100% pixel perfect image when playing through an upscaler. Now I've been playing it exclusively on a CRT for years, though, and I don't notice any issues there. I'm not very knowledgeable about video interferance like this, ...

Those updated background tiles look great!

How about flagging the bank swap routine as "locked" until it's done and then skipping sections of NMI that would compromise any of those registers? Or perhaps have have flag set to indicate whether NMI is running and then check that at the start and end of the bankswap routine? If NMI happened duri...

Not saying this to be an ass, but while you wait for someone to take you up on your offer, you should try to see if you can fix it yourself. This particular rom sounds quite obscure and I think it might be hard to find someone willing to dig through the rom, figure out what's going on, play through ...

Don't try to mod the cart, just get a flash cart or an NTSC console. I have both a pal and ntsc NES modded with NESRGB hooked up to a CRT TV. No messing about with upscalers or modding game carts, just buy whatever region game and play. You could also buy a cheap flash cart for the right mapper from...

Or do you keep a buffer of collision boxes that gets updated with every nametable change? I'm not sure what you mean, but I'm guessing that the answer is no. Perhaps buffer wasn't the right word. What I meant was if you were keeping a representation of all the collision boxes in RAM and then update...

It took me around one month to come-up with this algorithm and make it work fast in the NES. Normally I would use sin(), cos() and atan2(), but since the <math.h> is not really available in this context, I had to wrap my head around it and come up with an entirely different solution. I'm attaching ...

This looks really cool! Have you found any issues in performance or rom space developing in C as opposed to assembly? How do you do your collision detection? With so many objects and platforms on screen, the fact that it stays at 60 fps is what I find most impressive. :) BTW, How do you even debug y...

Is this usable on its own to edit an INES file's tiles? Or do I need to do my own import/export from an INES file? These tools are meant to be used for making graphics from scratch for new projects, using it's own specific formats. I think you would have little luck using it for any hacking of an e...
