Yea, Channel B should be soldered; Pin 2, the NC doesn't matter. Looking at the photo, it kind of looks like Pin 22 is also not soldered (?). Thats the clock so if its not, solder it.

I'm guessing some of the reason is the manufacturing infrastructure at the time. Most assembly lines were setup for through hole till the mid 90s and by then there was no point to switching over to a SMT design (re-design cost for a system reaching end-of-life). Re-tooling pick an place bots and mov...

To be fair, NOACs are not "awful". They are infact a very accurate clone of the NES/Famicom hardware. Most we find these days do have the mixed up APU duty cycle setting, and tend to have the cartridge port wired wrong leading to the incorrect sound and compatibility issues. But other tha...

It doesn't sound like a triangle kick, and they're obviously samples to some degree. They remind me of Ultimate Stuntman's samples, which were actually 7-bit samples. If it was made with Chip Maestro, then there are no samples; it can't do samples. Not entirely sure but I think the CM does have sof...

EDIT- Yea I figured it out!! The fixed 8K bank at the end of the Bin did the trick. :) OK so vegaplay has been in my lab for a couple weeks and I have mutated it a bit. But I'm at a stumbling block. I have things setup like so: iNES Header .BASE $7ff0 .DB "NES", $1a .DB $04 ; size of PRG R...

OHHH.Now it makes sense!

Thank you that clears things up for me somewhat. With the wiki example again $070: 05 05 05 05 05 05 05 05 This NSF has 6 4k banks in it, numbered 0 through 5. It specifies that each of the 8 memory regions should be switched to bank 5," Would this imply that 'bank 5' is >24K? or are all the 65...

There are two different cases: 1. Not bankswitched. - You have a 40k block of RAM mapped to $6000. - Copy the data from the NSF to the LOAD address in this block. - Write protect $8000 to $FFFF, or if FDS expansion is used write protect only $E000-$FFFF. 2. Bankswitched. - You have a 1MB block of R...

Hi guys and gals I need to confirm a question regarding the NSF header and banking control. I think I understand When the song is loaded into RAM, it is loaded into the banks and not the 6502's address space. Once this is done, then the bank control registers are written to set up the inital bank va...

If you assemble the FT driver at $E000-$F7FF and the NSF player at $F800-$FFFF, everything should fit. Then you can bankswitch songs into $8000-$BFFF and samples into $C000-$DFFF. Thanks tepples. The more I think about the export asm/bin the better it sounds. Thinking of a build tool to target a la...

The FamiTracker driver is about 5.5k of data, as I recall. You can locate it anywhere you like if you build it from source. If you need to bankswitch DPCM, you probably want to keep it out of $C000-DFFF, but other than that there's no good or bad place for it; just depends on your other needs. The ...

Something that may make this easier: FamiTracker has an ASM export option in the NSF export dialog. You can use this in combination with the FamiTracker NSF driver source to rebuild your music at whatever address you need. (You can also make any necessary modifications for banking, etc. this way.) ...

Good to hear, glad you got it worked out. They DO cut corners with Laptops, run into the same sort of issues with the USB

I guess I should finally make a new version of that Vegaplay special chip package, even if I don't really need it anymore since I implemented NSF support in my own emulator. That would be cool. Just re built my test ROM, works great. Thank you again! A Plus for the insight on setting the VRC7 mappe...
