i will be have one soon sold to me AS SPARES OR REPAIRS the guy has offered other one to me i dont know what to do
I finaly disassembled my unit. I make detailed pics for all of you. Hope you enjoy it. On the MCD controller pcb you can see an us-cdrom sticker. So what do you think whats wrong with the drive? Its an KSS-240A drive. Can i replace it? I like to get the cd-drive working... Hope you guys can help me. Here the pics i made for you :thumbsup:
hi guys got mine today i have black and white on pal 50hz 60hz is colour and i did have to change a fuse i did make the room dark just in case i erased any chips but i broken the pins on the mega drive part socket ordered new ones on ebay i will do a you tube video soon as i get a chance i have been busy today spend all day today on it i need a brake i put a new drive belt on my cd rom drive jackhead i can sort your drive out for £12 i will change the laser and drive belt i have done my own and i will guarantee you it will work pm me and let me know
well £12 is not the problem. I re your PM. Tell me what you need for fix. And maybe you tell more about the problem, i like to know.. I love to see the unit running. Well i try to connect the fan on the MD pcb. I got only an small support. Fan is running but very slow... :banghead:
other wise just send the hole unit and i will have a look and sort it out as i do have some broken mega cds bits around in my bedroom
Get a retail unit and swap the drive. FYI some dev models will only power up and eject if you have a cart in the slot. You should then get the bootup.
I never got an bios screen. The Unit allways boot on MD side with an cart. Without an cart nothing happens... I try different settings and constelations. I wonder that the light for the EMU/Drive button is very low :shrug:.
checked a fuse if not could be a ribbion cable i know its a nightmare to remove them like i said i could try the bios from mine unit if you want me to and if i get it working if you want me to change the battery and laser and anything else let me know it will be fixable even i if i am all day find this fault
@raylyd or Assembler: can you give me the dip switch setting for booting another region for the mcd please ? BTW I have scanned my board http://www.megadrive.org/~elbarto/mcd_dev/
update youtube video http://www.youtube.com/watch?v=pO6ry9kUKIs of it working to show that i got it working i did have to change all the caps on the mcd side
EIBARTO I CANT CHANGE THE REGION ON MY MCD PART I THINK SOMEONE HAS JUST PUT A JAP BIOS INSIDE HERES THE SEGA MPR-14088H-T LET ME KNOW IF THIS WHAT RETAIL CONSOLE ITS FROM I AM GETTING THE OTHE UNIT SOON AS NEXT WEEK I WILL SEE IF THAT HAS THE RIGHT BIOS SO I CAN GET A HEX/BIN TO FLASH A BLANK EPRROM SO I HAVE TWO WORKING UNITS WITH SWICHABLE BIOSES
If the rom on the mcd pcb have a MPR-XXXXX serial then yes it is a retail bios. I don't have jap mcd so I can't tell you which revision it was but you can test all the current dumped roms in a emulator and see which one is the same. (You have the revision at the boot screen on the top).
yes version 1.00 should it not have a retail bios i had the other unit today fix it was same fault as othe unit caps and fuse has japan bios 1.00 the drive had to changed due a broken plastic unitl i find a way of fixing it any way i thought this console was region free uk us jap they must have changed the bios chips to retail and the mega drive runs at 10MHZ not 8MHZ that could be other prob if it dont boot other than that i will have to wait to find some software to reflash the unit and hope to find some kind of instructions and one has a fan but dont work at all i will need a repalcement asap it uses 12v fan one of my unts did not have a fan but i will add one i will be putting more pictures up soon
My Unit is on the way to you. Hope you can fix it. I dont have replacement parts for fixing my problem(s). Thanks alot!
ok cheers mate will pm you soon as i get the unit and how its going and i will tell you if i get it to boot
jackhead has got the unit and he likes what i done if any one needs me let me know i can do a service for most segas most of the time there are repairable if not i will solve it no problem to big or small
