Hello, all.

I've played a little bit with C64 ROMs in an emulator. I'm interested
in putting a custom ROM into a real C64. I'm not very interested in
buying the burning hardware and learning the process, so I'm wondering
if there's a way to have one burned for me. Does anybody know of a way
to get a single ROM chip burned by someone?

Also, is the ROM in a breadbox C64 easy to change?

Thanks in advance,

- Kertis

Yes but this is distinctly non-pointful. What happens when you realize
the code you emailed out contains a mistake? $30 will buy you the
hardware on eBay.

Yes.

If you don't wanna do the burning, are you sure you want to do the
soldering?

Usually you need to desolder the ROMs (which is equal to destroying them)
and then you can either solder a socket there or solder the new ROM
itself.

Huh? How is this equal to destroying them? They're DIPs, it's less than
five minutes work to desolder one, and it's nondestructive (though I
wouldn't like to do it more than once to the same PCB). Plus they are
often socketed already; in fact, always so in the breadboxes I've
opened.

Good point. I guess what would make it more comfortable for me is a
nice guide to burners. What chips to use? Which burners work best? I
think Google is my friend here.

The original idea was that if there existed a web site that would burn
and ship the ROM for $10, it would be worth it to me. How many chips
will I waste while learning to use the burner properly? All the chips
that I've done this sort of thing with have been field-programmable and
pretty well-documented. (PICs, AVRs, etc.)

(De)Soldering doesn't bother me at all. Aquiring hardware, compatible
software, the right serial port, compatible chips, and then figuring
out how to make it all work together *does* bother me. I'd rather
spend the time writing the kernel code and playing with my C64.

I'd like to see a nice all-in-one guide to doing this. Any
suggestions?

Thanks for your replies!
