SOLVED!! The great Genesis Model 1 comparison list

[Dimitri]

My Genny doesn't have the "High Definition Graphics" verbiage, but it does have the DB9 EXT port on the back. (I don't think anyone's mentioned having one like that yet) Model number is 1601, and it has the license screen.

I don't have any old EA games to test with it, but I'd assume that they wouldn't play without a Genie since the license screen is there.

Serial: 020039833

It can play my copies of Master of Weapon and Japanese Herzog Zwei with no problem.

The region check is unrelated to the license check. They are both licensed games without a region lockout, thus they should play on any Genesis/Mega Drive system.

Here's a summary of the data so far:

Genesis
39W28536 - 160? - "Hi Def" text - EXT port - No license check
39U92969 - 1601 - "Hi Def" text - EXT port - No license check

020058252 - 160? - "Hi Def" text - EXT port - License check

110000266 - 1600-05 - "Hi Def" text - EXT port - No license check

Hmm... so far no confirmed Genesis #1600's?
YoshiM & chrisbid - are your units model no. #1600 or #1601 ?

More data needed!

[qbertandernie]

dont know if this matters cuz i havent tested them yet, but i have teo 'high def' 'ext port' '1601 systems...one has paper labels on back, one has plastic like labels.

guessing one or the other may denote lockout or not? like maybe they switched to paper labels to offset the cost of the chip install?

maybe not...upon further checking, the paper label ones made in japan, the other in taiwan

Oops-forgot to mention that my Genny has the license check.

Ok, this is interesting: I have 2 genesis model 1's, both have Hi Def text, and ext ports, both are model 1601.
Serial number B20332121--license screen
Serial number 39V24870-- NO license screen

It seems to me so far that the ones with serial #'s starting with a 3 are non-chipped, since none of them have had the license screen.

Couple more thanks to folks at Sega Dreams:

Found the other Genesis 1 systems i had sitting around:


130019602 -1601 -no text -no EXT port - license check - ports on right -made in China

020850171 -1601 - no text - no EXT port - license check - ports on right -made in Taiwan

My sound distortion system had its ports on the left and it was made in Japan

Here's some more:

Genesis

020973516 - 1601 - no text - no EXT port - License Check
B10212057 - 1601 - "Hi Def" text - EXT port - License Check

It seems to me so far that the ones with serial #'s starting with a 3 are non-chipped, since none of them have had the license screen.

Not just a "39" but the third character was also a letter and the serial numbers are only 8 characters long. Definitely seeing a pattern here, but we won't know for sure until we get some more entries.

Good job everyone!

[Evil E]

Surely there are tons more Genesis owners on this site that can chime in and help the cause!!! I am now curious about this as well!!

Indeed, it'd be great to be able to tell them without hooking them up. I'd also like to know if anyone else has a a system like mine -- with the EXT port but no text on the top...

[goatdan]

Hmmm...

There is some an easy, easy way to tell. Unfortunately, I don't remember what it is now. I know that it has worked for 50+ Geni 1 systems that the GOAT Store has had though flawlessly.

I'll see if I can figure it out soon and post back here.

[goatdan]

I figured it out.

It has nothing to do with serial numbers. Well, I guess it could have something to do with serial numbers, but I don't know what it is. The key that I have found is much simpler. Check the FCC ID in the sticker furthest to the left side of the console.

Does it say FJ8USASEGA? Then it is a TMSS version.

Does it say FJ846EUASEGA? Then it is a non-TMSS version.

If I'm incorrect, I have them backwards. Like I said in the post above, this has worked so far in identifying about the 10 non-TMSS consoles out of about 60-75 that we've had in stock. As of yet, it has never been wrong.

If anyone wants to confirm these for me, I'd appreciate it. We stupidly figured it out and then never wrote it down to actually remember what it was

On mine the non-chipped one is indeed FJ846EUSASEGA
and the chipped one is FJ8USASEGA. You are correct as far as my two genny's go.........

Okay, then I think that I can say that so far, this has been right in about 62 cases out of 62, if we include your consoles I really do believe it is true. I don't know why Sega had to apply for a new FCC code for the change...

I'm kind of tempted to take two of them apart and look at the guts carefully. I wonder how big of a change it truly was?
