| Hi,
I was wondering if any one knew of a project whereby one could build a
writeable mega drive cartridge - a 16bit equivelent of SMS reader
(http://www.smspower.org/smsreader/)
Thanks

how would you do a homemade writeable genesis cart ?
i m interested in it ^^

My suggestion would be to use a flash to store the programs, and build a
programmer around it. That will be for the PC side of things and on the MD
side, if you want to handle large images or large number of images, I'd
recommend implementing a memory mapper and bootloader in a cpld. I'd do
this myself but I don't know much about the MD/Genesis. If someone out
there is willing to explain how memory mapping works in the MD/Genesis,
I'd be happy to design something. I guess-timate it will cost about
$50-60AUD($35-45USD) if I was to manufacture it.
BTW I don't actually have a Megadrive anymore so anything I do is purely
working off specs, so be warned.

I should add that you can also use a Super Magic Drive (SMD) with an adapter
for the Genesis/MegaDrive.

How did I get *that* wrong? The SMD works natively with the Genesis. An
adapter lets you use it with the SNES too!

Thanks for that Mark, not that I would've minded duplicating work but I'd
rather not have to if I don't. Although its a little useless for me
personally since I don't have a Megadrive anymore. I had a look at the mcc
and I think it could benefit from some integration by way of implementing
much of the logic in a cpld. And for permanace it should be using eeprom
or flash. It would reduce power consumption and decrease part count.
If I have time during this summer( its summer here in Australia) I'll
prolly take the mcc as a starting point and optimise it.
And to the original poster, there you have it the mcc.
There you have it I've already done it without lifting a finger

Hehehe, I guess there is little left for me to do in this area. :P
And Mark, I just noticed the iinet in your email, so I guess there is
little point in giving a local weather report. 
Oh well, back to hacking my C64.
