Yet another crap?

All of the games are Mapper1 (SLROM)
The menu code was originally Mapper 4 and I had to convert it to Mapper 1
Special thanks to Master Oliveira for his great idea of generating clock signal by using WRAM CE and CPU R/W, without his help I would get stuck on using address lines for clock signal!

By the way any idea on how to run this rom with emulator?
What mapper number should I use?

I think you'd need to get the spec onto the wiki, claim an NES 2.0 mapper number through the registry on the wiki, and file feature requests in emulators' bug trackers.

Hey, I like hearing about the things you've assembled!

Unfortunately, there are almost no MMC1-based multicarts. Mapper 105 (NWC) is the closest we can get, and it's basically one SGROM plus three NROM games.

Excellent work as usual. Maybe you or someone else can test it with an original mmc1 and on an original nes.

Good job!

You can use a unif board to support this mapper!
I can help you support this mapper on my vnes plus!

I'd be down to build it after finals in mid December

nice cart farid!

May I try to use a gal16v8d replace the two 74!
And how to write the cupl sourcecode?

Yes, this is really a great idea.
I found these, but they are not free :
GAL16V8 Data Sheet
ISP Engineering Kit Model 300 Data Sheet
Lattice Diamond Programmer Software

Lets find a free project to use

Edit 1 :
And here is a very neat programmer : Uprog LITE / LPT

Edit 2 :
Oh,well it seems Uprog is not free, is it?!
But don't worry here is another FREE one, YES! :

GALBlast Version 1.6

I have the programmer
So I need a guide to write the abel or cupl code.

Maybe you can use this tutorial :
Schematic and ABEL-HDL Design Tutorial

Check out WinCUPL. It's very simple to use, and has a built-in waveform Simulator.

FARID, please upload a picture in the first post they do not appear

There you are, I reuploaded them and added a cover, have fun

thank you!

There is a possibility for a future version 4 in 1 for 27C040 users?

I'm pretty certain you should be able to just take the first halves of the resultant images and have it work: the 74'174 has been wired to boot the cartridge into the first 128KiB.

You'll need to modify the menu to only offer the first four. (otherwise 5-8 will map to 1-4)

There is no need for 74HC238, WRAM CE can do the job alone as a clock signal for 74HC161.
Also I have a clone MMC1 which don't have WRAM CE at all (it is NC), for this kind of MMC1 the clock signal can be generated by decoding STA $8010 with 74HC139 :
CPU R/W = 0
/ROMSEL = 0
PRG A4 = 1

This should work (From the first post) : Menu Patch


Yes, they also work


It should work, check everything again.

Soldered this scheme. Rechecked. Menu filled from the first post. Cartridge menu starts - games does not change.

Does it work with the schematic from the first post?

From the first post I did not. I want to do that this would work. I'll collect the cartridge MMC1 and MMC3 on the same board. I need that to one scheme worked with two mappers.

Check the following:
* Make sure you've wired the resistor/capacitor/diode correctly. The voltage on pin 1, while the famiclone is powered and reset is pressed, should be 0V. It should then go to 5V once you release reset.
* Make sure pin 2 is connected correctly.
* Make sure pins 7, 8, 10 are grounded.

Also, try changing the capacitor to be connected to ground instead of +5V.

There is a menu for MMC3 mapper for games 256 kb.?

Farid had previously made this one for 128 KiB MMC3 games, but it could easily be modified to support 256 KiB PRG instead.

This scheme does not work with the menu 8 in 1 but it works with the menu under MMC 3 mapper for games ninja gaiden 3 in 1

Posting some pictures may make me passionate

I do not understand
