As you may have seen from the other forums, I've been working on a NES emulator though I think I've gotten most of what I wanted out of that now. I still want to work on actual NES games. As for mapper hacks, I have no current plans. I was thinking about trying to do some Konami VRC series games.
I also was hoping to build cartridges for the hacks mentioned in this topic, but the EPROM programmer I bought didn't work and I don't have the money to spend on a USB EPROM Programmer right now.

To make a TKROM into TKSROM you just need to rewire CIRAM A10. Cut the CIRAM A10 wire that connects the mmc3 pin 10 to nes connector pin 22. Then solder a wire from nes connector pin 22 to mmc3 pin 12 (chr a17). You may have to cut the chr a17 trace that goes to the chr rom, but it should be unused on the 128KB chip anyways.
The wiki seems to be wrong in saying A16 is used for mapper 118. Bootgods site shows Play Action Football uses TLSROM (no wram) so modifying a TKROM should be much easier.
has anyone tested this to see if it will work on a live cart? thank you[/quote]
So let me make sure I have this before I break out the ol burner and give her a shot. Wire it just like any normal TKROM board, PLUS add what is above?

Yes Tormenter, I believe you have it right. Basically the game is a TKROM game except that Buzz & Waldog uses Single Screen Mirroring, which MMC3 can't normally do, so it TKSROM which you can convert TKROM into by doing the steps mentioned. So do it as a TKROM reproduction, and then do the CIRAM A10 stuff to convert it to TKSROM.

According to Kevtris, the CIRAM A10 is on the image, the bottom of the mmc3 chip, 2nd from the right, correct? I do not see this leading anywhere on the front, and you turn it over and it does not lead anywhere either?

I found two server-side problems with that image URL:
- The img tag in phpBB appears to work with only a few URL extensions. To work around this, use URL rewriting, or use AcceptPathInfo = On and $_SERVER['PATH_INFO'].
- The server isn't sending out the right MIME type. It's sending text/html, not the correct image/jpeg.

Sorry guys, a while back I had to implement a number of things to keep image leechers from bringing my site to a standstill. No hot-linking and the images are embedded into the document (hence the MIME type).
You can view the image by going to its profile page first:

I believe you are looking at the chip upside down. The pins are at the top in the image and it should be the second from the left.
