Quoted from Aurich:

I haven't used the software yet, so someone correct me if I'm mistaken, but I believe it's technically 15 colors, and the 16th slot is used to store the pallet pointer.

It's 16 colors / pallet

Quoted from Dmod:

There appears to be confusion about the role of the Pinball Browser and SmartDMD

There are 2 threads on Pinside dedicated to Pinball Browser and SmartDmd, the differences and relationships between them are very clear.

Quoted from Dmod:

The Pinball Browser is being used to modify Stern's copyrighted game ROMs to substitute color indexes in place of the original 4-bit dot intensities, resulting in data loss and flattened artwork

A ROM is just a component like any other part of a pinball machine and the end users have the right to modify their games as they see fit. Btw, that's what they do when they install a ColorDMD (the cabinet design is also IP).
Some even think that displaying the original copyrighted artwork (the IP of the actual license holders) with added colors, like ColorDMD or SmartDmd do, is not allowed...

Quoted from Dmod:

...resulting in data loss and flattened artwork

This is just your opinion

Quoted from Dmod:

The SmartDMD display device implements a limited subset of ColorDMD's protected IP (US 8,773,452 B2) to generate a tag from the first eight dots (in this case, a palette identifier), and retrieve color information for the frame.

This statement is wrong : SmartDmd does not need to identify the frames like ColorDMD does. SmartDmd is just using the color information that is sent by the pinball machine.
The key point here is that ColorDMD uses a "frame tag" which SmartDmd does not.

Quoted from Dmod:

The ColorDMD display utilizes custom hardware that is also capable of more complex algorithms to extract a tag without the need to modify any manufacturer IP.

Yet you are still modifying the way the original artwork looks

Quoted from Dmod:

Olivier and I have corresponded several times in the past about ColorDMD support for modified game ROMs.

This is correct and you never mentionned anything about the fact that SmartDmd was using any subset of ColorDMD's protected IP.


This kind of discussion has nothing positive to add to the pinball community and I will not argue here any further. I will never criticize your product like you’ve done with ours; it is just a question of respect.

Well, I have heard the criticism about the 8 lost pixels and I have added a new mode in SmartDmd
See here for more details

Quoted from flynnibus:

Why would it need to be configurable unless there is some trade-off??

No trade-off, just backward compatibility

Quoted from kapsreiter:

@Mike
how will you define mix mode mode
so that some scenes will be upscaled and others not ?!?
i thought this could only be a global setting for all ??
thx
tom

You can define the upscaling mode for each palette.
For example, Anti-Aliasing for concert videos, 16x for cartoon animations and 2x for the other ones.
