Re: Standardizing symbols for PCB mirroring pads

The topic New Famicom Shells (Available Now) by muramasa shows a board with "H" and "V" pads for nametable mapping without making it clear whether that means arrangement (as on Nintendo boards) or mirroring (as on some other modern unlicensed boards). Is it time to standardize less ambiguous symbol...

New Famicom Shells (Available Now)

Brand new Famicom shells are finally available! The shells are inspired by the shells commonly used by Koei games. We picked this style for a couple of reasons. First is the shell is secured together with four screws. One of the big challenges with making any Famicom games is dealing with the snaps ...

Re: AX5904 MM1 clone incompatibility, or RAM issue?

I have ran into issues with certain games not liking faster sram. Final Fantasy III and Sweet Home are good examples of having this problem. It would be interesting to have you try to switch the SRAM between your boards as well. I found 120ns seems to work fine.

GameGenie for the Famicom.

I debated whether I wanted to show off this project. Not sure this will ever become an actual product. It came about after harvesting the chips off of some FDS Ram adapters and wondering what the base could be used for. After thinking for a bit the Famicom Game Genie was born! https://www.muramasaen...

Re: What reproduction carts are available?

There is also Muramasa , but they don't have any donor-less non-discrete mappers yet I think. Haven't tried them yet. I hope to try the Famicom repro carts when they come out. Thanks for the shout out. Right now most of our boards are DIY. We do have a MMC1 and MMC3 board that include the mapper ch...

Can anyone help me identify the diodes on these? I can see they have stripes but am partially color blind and am struggling to identify them.

Re: FDS RAM Adapter - NES Version

I remember playing with that FDS RAM adapter on a Famicom with CPU (UA6527P), PPU (UA6538) and crystal (26.601712MHz) replaced from a Dendy and it immediatelly hang out after showing the loading screen, so be prepared that it might not work on PAL console without modification of the FDS Bios.

Re: FDS RAM Adapter - NES Version

Looks like you did the transplant I'd expect. How did you choose to map EXP pins to 2C33 signals? Yeah more then a transplant is a bit out side of my skill range at the moment. I went ahead and made the board with footprints for the 4 dram version or the single dram version. That way no matter whic...

Re: Famicom Disk System power board schematic

Nice! This is on my list of things to do at some point as well. One thing you may want to do is make a version that is compatible with rewriting disks.

Re: 5V->3.3V converter

This is great! I've considered doing something similar but an NES version that you could put the game inside a new shell at the proper voltage.
