MMC3 on FPGA?

Post by Online »

Hello everybody. Recently, I came across the fact that I saw such an adapter on the board for an FPGA unknown to me. Tell me. please, what this the microcontroller and how can you implement mmc3 on FPGA? Can I dump this mmc3 firmware with it? Found also on verlog nes mappers
MMC3.v download here
https://github.com/ClusterM/nes_mappers ... 4%20(MMC3)
I'm new to this question, can you please tell me what is needed, in addition to the firmware, to use this FPGA instead of ax5202p (dip40)?
I will be very grateful for any information :)

What you see there is almost certainly the COOLBOY or MINDKIDS MMC3 clones "SMD132" or "SMD133", instead of programmable logic.

Do you have a link to any inexpensive sample where the ASIC data is located?

Try looking at an FPGA NES project, it would have an implementation of the MMC3 as part of supporting mappers. Also make sure the author is okay with you using their Verilog code, check the software license, etc...

Hello, friend, I need this ASIС itself, where there is mms 3, to make a cartridge on which I can change games/ I'm wondering where i can buy it To move on other pcb. (so that connect this asic instead of 5202p on DIP40)
Or a link to these asic and some programmer to sew the mmc3 configuration yourself, can you advise?

No sir. Unfortunately, I did not find such a chip there. Maybe you have a verified link where exactly this ASIC is found (QFP-package)?

That is the chip-on-board version of the SMD133. Here is the QFP version:

I will try to do MMC3 on CPLD soon when I have extra time after work. That will be in this thread:

To get a board with the COOLBOY or MINDKIDS MMC3 clones "SMD132" or "SMD133" chip (not a blob) from AliExpress, search for 150 in 1 cartridges with save, usually it's have Kirby's Adventure in the game list and the seller guarantees that it has the save function.

Do we know if that MMC3 clone chip can be run directly on 5V? Or is it a 3.3V chip like the ROM and RAM in those cartridges?

We know nothing about it, but it doesn't instantly die when supplied 5V.
