i have it set for vertical according to this page http://bootgod.dyndns.org:7777/profile.php?id=523, but i dont see how something like that would cause the pause menu to appear over the main menu Looks like they must be pre-loading the pause screen into the other nametable. So when it pauses, they ...

Possibly the mirroring jumper has the wrong setting, there's not much else that can go wrong with NROM.

Are they the note lengths? Since it's 1 through 4, I would guess it may be 1/8th, 1/4, 1/2, whole notes. Or could be 1/16th through 1/2, I don't know. If you change the first one, it should desync the timing between channels for that song, try it. Or maybe it's the channel select for the note? There...

Thanks for checking it out. To be clear, it can't go on any multicart, the way it is now. While the ROMs are freely downloadable, they're not public domain, and have the caveat that only mame.net can distribute them. The copyright holder has since died, so there's no simple way to ask for permission...

This is far from complete, and not really playable, thought I would dump it out here anyways in case anyone is interested in the technical side of it. It was fun as hell to make, but I don't know if/when I'll ever have the time to get back to it. https://github.com/Memblers/nesxidy (description copi...

I'm loving this thread, good stuff. Regarding OAM DMA, if your mapper is watching the bus and is fully in control of CHR-RAM (big IFs, I know), there's no need to hijack the CPU bus. Other than for palette setup, you'll not need to touch $2006/$2007 when you have a VRAM port in the mapper. Do the DM...

Im here for arpoths too. What up memblers!? Also, do you still have ass-raping Vikings on the high seas anywhere? It was a sequel I made in the early aughts. I think I sent it to drew. Hey man, it's been a while! I do have that. There was another XM with it, both are really fun tracks. I was meanin...

You might want to look at the NSF rips instead of the full games. NSF files have INIT and PLAY routines. The init routine basically is how you "load" the song or sound effect. Play routine simply plays it, called 60 times a second. Usually the person ripping an NSF file has to insert their own code ...

The dual 6502 processors, by sharing $6000 - $7fff. The cart carries a noac (umc6561). The two systems run different codes respectively, and shake hands through IRQ. All buses need level shifters for separation. It looks like the VS system? Now that is a fun idea. If the cart also had A/V output an...

I am affraid I dont know how to add coins tracking, nor change the logo.. I could probably design a new board and get that working but the palette and coin acceptance things would be out of my league :( If you do take on this project, you might want to consider supporting the PC10 version. It's the...

What would make the Squeedo Jr. design cheap is what it lacks, not needing a PRG ROM, CHR RAM, or WRAM chips. The board itself is NROM-sized. Well, technically there is a PRG-ROM (made from a level translator chip) but it's only 1 byte - $4C. So it sits in a JMP $4C4C loop during configuration. Whic...

I have a project that I call Squeedo Jr. that sort of is like the SA-1. Sadly, it's been idle for a few years, far too long. Most likely when I do try to make another NES cart board, it's likely to be that one because it's the one I've been most excited about, by far. It's fairly ambitious and would...

I found a video of somebody recording off of a SMB arcade machine, and although he does have a brown shirt, it's a much darker shade of brown than what I typically see in emulators. https://www.youtube.com/watch?v=mKk2TkKRAC0 Other than the different PPU, I think Nintendo's VS and PC10 cabinets nor...

Oddly, SMB does something like that, too. It ramps it up to $30 when you're playing, then ramps it down to $00 when you die. But why, it's a mystery.

For a debugger you might try NESICIDE. 8bitworkshop might work for that, too (it's a little tricky to link with it, there's info on the forum about it though). Looking at the source, I'm not sure where the NMI gets enabled. It is calling the audio update from NMI, which is correct. There's potential...
