1942 Logo: Emulation vs Arcade/FPGA (Patreon)

Not many people noticed, certainly Sorgelig did, but the CAPCOM logo at the boot up screen of 1942 is different in MiSTer and MAME. MAME version shows two different boxes moving, whereas MiST(er) version shows just one long box whose length varies. I made that core using only schematics. I didn't have a real PCB and I couldn't find any video of that logo animation on YouTube. But the logo behaviour made sense to me from the schematics point of view as the sprite RAM space was divided in sections for all screen, only left and only right. Something that MAME driver does not take into account.

At last today there was a post in Jamma Arcade about a repair log of this board. On one of the videos the logo from the real arcade can be seen. And yes, the one you hold in your MiST(er) board is the right one :-)
