On 2nd december is started to build a MD cartridge R/W device whis is 100% designed by me. Today (5th) I got it working correctly, I dumped my Sonic & Knuckles cartridge. It took 45 seconds and the result was a perfect bit accurate copy of the ROM image. If I ASM optimize my QB45 code (I love QB45) I believe it would take 30 seconds.
Some pics of it are on my site's MD section, documentation, schematics, software are being prepared and soon available.

Wow, that looks rough.TmEE co.(TM) wrote: Some pics of it are on my site's MD section, documentation, schematics, software are being prepared and soon available.
Can't wait until it's finished though.
If I replaced the rom, in a sega cartridge, with the flash chip, would it be able to program it?

Its rough indeed...
It is rough, but it works !!! I dumped most my cartridges, messed with backup RAM on Sonic3 cart and
even BURNED an EPROM !!! Man, EPROMs program easy. I started to write the documentation and some instructions.

Re: Its rough indeed...
A friend a I were discussing that last night. Is the eprom programming pin on the edge connector? Would it be able to erase a flash rom?TmEE co.(TM) wrote:...and even BURNED an EPROM !!! Man, EPROMs program easy.

The VPP (12V programming voltage) pin is not on the cart slot, but it could be if you like (use some unused pin). I used a wire for that. I'm working on EPROM stuff as all EPROMs are not programmed the same way. There are lots of Flashes out there, if its industry standard and 5V it can be used with MPCP. Erasing is possible. I need to build some adapters to support more memories and downloads datasheets aswell.
