What's up with the IDs on 0x10^c hardware?

[azertyfun]

Old 0x10^c hardware has two IDs documented, one for "older models" and one for "newer models" (see LEM1802.txt). Is it to comply with ID specs? Or is it something else? Which one is in use in game?

Yes, this is in fact related to getting these items to match up with the Device-ID method. The game and emulators are currently using the "older models" ID, in which the attribute bits are "wrong". I didn't want to replace the full IDs outright because that would break things quite a bit.

Depending on how impractical the idea of attribute bits is, it might make sense to drop them and revert this. This maybe requires a bit of discussion, although I am more in favor of keeping it, in which case software can AND the high word of the ID with 0xFFF0 before comparing to a fixed list (ignoring the bits that are different in this).

What's our status here @Meisaka ?

I was hoping to get #16 merged, and change one of the bits to indicate the presence of an EEPROM, at which point these kind of changes would be more finalized.
