A post was made long ago, on some Sonic board, I forget which. It identifies a way of telling which revision your cart is by using a Game Genie - I assume locked on to S2&K.
GNBT-BARN: rev. 00
GNBT-BAR4: rev. 01
GNBT-BASJ: rev. 02
The code that triggers the "NO WAY!" screen identifies your cartridge revision. For example, if you input GNBT-BAR4, and the "NO WAY!" screen comes up, your cart is a rev. 01. The game should start normally with the other two codes.
Let's find those other two revisions!
I did this, three out of four carts were rev 01, the other is.........Rev 00
I tested it a few times to make sure I did the code right,
I should be receiving a cord from MoD within the next few days, and I will dump this sucker!

Um, are there pigs?
I didn't see that post. Are you sure we didn't have 00 all along?

No pigs. This ROM is not dumped yet, just check the header. All we have is Rev. 01. (and presumingly Rev. 02 from Sonic Compilation)

I wonder if this will be another case of byte identical dumps? :P
Posted 29 July 2005 - 03:04 AM
Nope. The header, at the least, will be different. :P
Posted 29 July 2005 - 04:03 AM
My version's revision 01. =(
So has this cart always been yours, Rika? Bought on launch day? Stolen from Naka himself? =P

Wow that's pretty cool! Does the cart have a different serial on the label? Or are those meaningless?

Something kinda unlelated...
I've noticed how many of you guys use the term "rev. something" for the version number. Well, it was only used by GoodGen in the old days so I guess there's no need to use it anymore.

No, we're calling it that, because that's pretty much what it is:
6: Product code and Version number:
* The first 7 characters are the product code
* The 2 characters after the hiphen is the version number. This will
vary depending on the the type of ROM or software version

cool, however im not being optimistic that anything but the header will be different.
Posted 29 July 2005 - 02:42 PM
It cannot be to much different, as it is able to lock onto S&K.
Posted 29 July 2005 - 03:13 PM
Well I'm sure when the lock on technology was made, they had all revisions of Sonic 2 in mind. Besides that, the ROM would have to be shifted to not work, according to drx.

I imagine that any differences will be in the program code only.
I don't know if KiS2 uses hardcoded absolute offsets for Sonic 2, or if it changes based on the GM code. Since the UPMEM is only 256K, I can't imagine that there's that much room to account for art in different places.
Perhaps that's a reason Sonic 1 wasn't compatible with S&K - I'm pretty sure that the two revisions have stuff moved around quite a bit.
