Just running through a few games and stumbled on a theory and was looking to see if it hold water.
For years we have been tracking variants on Nintendo Games (for me it's GB). One thing I have always wondered why manuals are not following the revision ie label identity. Could it be as some suspect "easier/less expensive to update and print the a CIB" (as @RH suspects) or is it quite possibly a non documented revision (i.e. no version bump on label)
here is the data..
GB: Legend of Zelda, The: Links Awakening has 4 cart versions and 5 manuals the label are as follow
DMG-ZL-USA (Manual and cart)
DMG-ZL-USA-1 (Manual and cart)
DMG-ZL-USA-2 (Manual and cart)
USA-ZL-USA-3 (Manual and cart)
USA-ZL-USA-4 (Manual ONLY)
Here is where the theory changes the whole thing.
Some time during the first year of production the programmers did some sort of bug fix/ change. Causing Nintendo to change the CIBs but that did not trigger a label version bump i.e. going from DMG-LZ-USA to DMG-LZ-USA-1. Such label change might have been reserved for a major (graphic) release. However to keep up with the correct data in the manuals they did a manual version update along with a box version update (this is a hole other can of worm). This would increase the actually cart count to 5 versions thus matching the manual count.
So with that data applied you get this.
Manual Cart
5 manuals and 5 carts,
DMG-ZL-USA DMG-ZL-USA (Original ROM
DMG-ZL-USA-1 DMG-ZL-USA (ROM UPDATE)
DMG-ZL-USA-2 DMG-ZL-USA-1
USA-ZL-USA-3 DMG-ZL-USA-2
USA-ZL-USA-4 DMG-ZL-USA-3
the manuals and games are accounted for
Tennis
3 manuals and 3 carts,
Manual Cart
DMG-TN-USA DMG-TN-USA (Original ROM
DMG-TN-USA-1 DMG-TN-USA (label variant)
DMG-TN-USA-2 DMG-TN-USA-1
other examples.
Tetris( @RH theory works here) it is plausible that bundles can account for the manual changes
6 manuals and 5 carts,
DMG-TR-USA org with ROM A
DMG-TR-USA label variant 1
DMG-TR-USA label variant 2
DMG-TR-USA-1
DMG-TR-USA -2
Super Mario Land (SML)( @RH theory works here) it is plausible that bundles can account for the manual changes
8 manuals 4 carts
DMG-ML-USA = manual blank -1
DMG-ML-USA(rom) = manual 2-5
DMG-ML-USA-1 = manual 6-7
DMG-ML-USA-2 = manual 8
Dose this hold water? How dose this data compare to say NES or SNES or even DS?
Is it plausible that some games have variants that are not yet documented?
