Re: Do you miss any NES-related software on Windows?

You could make a desktop/offline version of NEScartdb. I know you said windows but that would also be a really cool offline phone app. So many times I was at thrift shops and I see NES carts but the website is down and I can’t check it. This is something that can work very well offline and not depen...

Re: Do you miss any NES-related software on Windows?

How about adding VT03 support in Mesen or FCEUx?

Re: Do you miss any NES-related software on Windows?

Does it have to be windows? There is lots of existing windows stuff that could be ported to Mac.

Re: Name of this game?

Won’t that just burn out the latch chips in the cartridge? It seems it just connects the conflicting outputs of the latches together in your drawing. When the latches burn out, everything should be fine/unprotected as long as the 7805 in the console didn’t burn out?

Re: SMB1 Working but not SMB3

Also, I believe /IRQ should be always high when you turn on the NES with no cartridge inserted, or when running SMB1. If you don’t see 5V, you may be missing a resistor from /IRQ to 5V, or may have the incorrect resistor, etc. You can safely add a 10k resistor from /IRQ to 5V at the cartridge connec...

Re: SMB1 Working but not SMB3

The only things I can think of:

- Dirty connector/games
- problem with /IRQ signal. The older games might not enable IRQ. This signal may need a pull-up resistor or something.

Re: completing iNES mappers

I made my own reset based carts years ago. I also made carts with dip switches. The reset based ones just eliminate the physical switches but have the same function. These carts can have any base mapper. I was collecting different mapper carts and making the applicable games selectable this way. I d...

Re: Need advice buying a NES-101 and a flash cart

If you use 6-character codes, the same codes will work on any cart. How about the NMI/v-blank vector? It may create unique challenges to not be able to use that. That will be 4 codes to replace both vectors. You might actually be better off changing the NMI vector only, then when the original game h...

Thank you org, I will do anything I can to help with MMC5/A. I have been very lucky to come across plenty of both revisions to share and keep for testing now.

You may be able to use a Game Genie to prevent initializing the SRAM.

Re: Creating NSF from scratch problems

Does your music replayer + song run in an emulator when you compile it? Or does that not work either? I haven’t played with NSFs in a while so I don’t immediately know what could be wrong. If you post a non-working, compiled NSF file, I can help debug it, which can then point us to what you did wron...

Re: NES PRG or CHR ROM Piggybacker adapters

After being confused by what you just said, I realize each tile is more than 1 byte... I am pretty sure it 2 pairs of 8 bytes (16-byte chunks) for each tile's pattern data. So A3/A4 makes more sense and A0 couldn't make sense based on your image. I am glad you were able to figure it out and nothing ...
