No, I actually meant 93C46, for high scores, savegames and such. I've got 27C160 down :)

Ah ok then.
Hmmm, I don't know if the higher numbers are compatible.🤔

They're not.

 

So, BSG has 2k EEPROM, and all the others (except some of CJ's ports) use the 128b ones?

Would someone be willing to burn the eproms and sell them?

That's when you start to get into a bit of a grey area around here.

I posted so everyone could make their own carts. While I'm sure there are people using this to make and sell, with this knowledge you don't need to be buying from them on ebay. Try making some yourself.

These would really be only for personal use. I'm just trying to see if there is a second option in case I can't accomplish this myself. I don't endorse anything that would degrade the hobby.

You should be able to figure it out but feel free to post questions if you run into trouble.  If you don't want to de-solder used boards to reuse I sell new Jag PCBs for $6.50 each.

Ok I need to post this.

 

Let me just say you are better off changing any .j64 extension to .rom, trust me it does make a difference!!

 

Take your .j64 file and rename it to .rom, split it and then program it. This information should be extremely helpful.

 

While some games will program and run as a .j64 some or at least one will NOT!

I had found that out a while ago when I wasn;t getting any of the roms to show up in Skunkgui to load onto a skunk. Changing from .j64 to .rom fixed all of them!

I finally purchased a Hakko FR-301 desoldering iron.  If you can afford it, I highly recommend you desolder using that rather than a Souldault.  Including time learning to use the tool, it took me about 45 minutes to remove chips from 40 pcbs.  You will save a lot of time and effort with the FR-301.

 

It is so easy to use and does such a good job, I had a lot of chips just falling out from the pcb.  Pics are example of how good it desolders.

Yep - I think that is the replacement for my discontinued Hakko 808.  I love the thing.  Desolder 40 in dips in under a minute, and like you said, they just fall out of the boards.
