Here are a few more I made. Each team gets two colors + white.

This is not a game that making it MMC5 makes any sense. It just means you never want it on real hardware, honestly. But good luck anyway. I think someone someday will figure out how to manufacture something for MMC5 homebrews. It's not like I can legally profit from this. I just want to make the be...

Creating more fields while developing the basic scrolling field. Many more to come.

I am building an NFL game from scratch. It is obviously influenced by Tecmo Super Bowl. I will try to use the full power of the MMC5 to maximize the quality of the game by using 1024 PRG ROM and 1024 CHR ROM. Many of my graphics choices are expensive but I assure you they are worth it. My initial es...

Still can't figure out how to properly select the proper tiles to place in the nametable for MMC5. I am hoping to use the extended RAM so that I can select from any of the 16384 tiles plus having custom attributes for each individual tile. I tried doing writes to the nametable at the beginning of VB...

I think it's nice that the mapper provides a way for you to tell whether the PPU is rendering or not, but that's not what worries me about the extended attribute mode, since there are other ways to detect the start of rendering. It's that you're changing the data as it's being used to render the pi...

Since MMC5 allows me to pick any tile from a 256K super bank, then I must have to make an additional write somewhere because writing a single value to $2007 won't be enough. What do I do? The MMC5 has 1KB of RAM mapped at $5C00-$5FFF, which is where the extended attributes go. The lower 8 bits go t...

I think it's pretty clear that OP is unconcerned with the NFL trademark issue. They've already been doing it for years at: http://tecmobowl.org/ I always wondered how the Tecmo fans could legally sell Tecmo Super Bowl carts with updated rosters. They've been doing it for years. I have been experime...

There are four sets of tiles: Left end zone Right end zone Midfield logo Field graphics that are not left end zone, right end zone, or midfield logo, such as lines and yard numbering Sets a-c fill 4K, leaving no room for d unless a, b, and c are swapped in on demand. You are correct but I am going ...
