EZ Flash works off a Micro SD card, correct?

If so, have you tried to re-format the SD Card?

If you print out your own board, you might as well emulate the MBC chip as well with a CLPD.

What would be the benefit of doing this? I've also toyed with the idea of converting it to a non-volatile board as well, based off of this: http://forums.benheck.com/viewtopic.php … mp;t=38664

I would have mentioned it earlier, but I wasn't sure how you guys would have felt about such a project.

10. We do not condone piracy in any form. Anyone posting links to illegal torrents and/or "warez" will be making an offense worthy of a ban from Chipmusic.org by its staff.

Regardless, I don't see why the subject of my project has anything to do with it? I still, would like, a drop in chip. I have no real background in electronics at all, and I was unaware that there was such an immense variety of chip that potentially could be used. I just assumed that there were a known dozen to pick from, and someone already found one that would fit.

Though this does not seem to be the case, which is quite obvious now guys, I guess I will go with the 49F040 chip that was mentioned by Jazzmarazz earlier in this thread, and try to make a redesigned PCB. In an effort to continue the discussion, if anyone chooses to, feel free to comment with any other suggestions. If in turn the admins, and or mod feel that this topic now violates any rules they may have in place, then feel free to remove this topic.

3-year project and no knowledge of flash rom chips??? Are you sure?!

My project incorporates many things, a programmable cartridge is only a small part of it.

Print your own PCB and you can drop in whatever chip you want.

I'd still like it to look somewhat factory. Which chip would require the least amount of re-routing?

how much for the rumble cart

Sorry, my carts are not for sale, they took me ages to accumulate.

Are you serious?

You have to pretty much re-wire all but maybe 4 or 5 pins depending on which cart pcb you use.


It seems like you want to DIY this yourself, but you don't want to put any work into it.

Grab yourself by the balls and be about that life or buy a flash cart.

I already have several flash carts, which I use to test my project.

If I wanted just a flash cart, I'd follow one of the many guides online to build one. What I'm looking for is something specific, which is why it was brought up in the first place.

I have a project, for my own interested, and it requires the cartridge to look as factory original as possible. If necessary, I can redesign the PCB, however is isn't ideal. This isn't a cry for my laziness. My project has been on going for over 3 years now, and incorporates way more then just a programmable GameBoy cartridge. This is merely 1 aspect of it. That is why I have come to this community for some suggestions and tips.

There is no programmable chip (that I am aware of) that is a drop in replacement pin for pin with the standard IC

Thanks, but I'm trying to replace the existing rom chip, with a new one (that I programmed) in the exact same footprint as the original rom.


why not just remove the original rom chip, and then solder the new one in?  if the footprint/pinout are the same, this would be the most straightforward way to do this

This is exactly what I am trying to do, but I don't know what chips would work as a drop in chip.

Thanks, but I'm trying to replace the existing rom chip, with a new one (that I programmed) in the exact same footprint as the original rom.

I'm looking to create a flash cart of sorts using a OTP chip. However, what I'm looking for, if possible, is a chip that is the same footprint as a factory Nintendo chip.

Does anything like this exist? I'd ideally like to have the original Nintendo board as original as possible, without all the additional wiring.

If this isn't the correct place to post this question, or even the right forum at all, please let me know.

Thanks!
