There's a high res die photo of Mickey & Donald done by digshadow: http://siliconpr0n.org/map/nintendo/dm-53/

I transcribed this ROM, too:

Oh! I'm sorry I didn't mention it before, dm-53 was already transcribed by Segher and O.Galibert.

*edit* I don't know if it's OK to publicize the link to segher's stuff, hold on a sec and I'll compare the 2 to see if there's differences.
I verified Top Gun with my usual doublecheck method btw =)

Yeah, it supports 63 steps per page, program will get stuck at $3f unless it has a jump instruction.

int feed = ((m_pc >> 1 ^ m_pc) & 1) ? 0 : 0x20;
m_pc = feed | (m_pc >> 1 & 0x1f) | (m_pc & ~0x3f);

I posted the Contra ROM dump from the patent:
http://www.seanriddle.com/contra.html

The scan is much better than the other 2 Konami patents, but there are still a few ambiguous bytes.

Regarding the current vectorized VFD Artwork, I've noticed that, compared side-to-side, they sometimes are not very accurate to their source.

This is specially noticeable when looking at certain cartoony figures, which sometimes look like they've been drawn by using tracing paper over the original art (kind of how other artwork in MAME would look if it was replicated by hand, I guess).

I ignore how these are being made, but perhaps there may be some alternative way of creating more accurate vector files out of the originals?


I fear that this could be a problem that will be carried over to all future supported handhelds, and will be specially noticeable in those with more elaborate graphics, licensed characters, etc, so now that the ball is just starting to roll, it may be a good time to look into it...
