X-Plan is an unusual shoot'em up / poker combo by Subsino that uses ariplaines in place of cards. The shooter is little more than a playable mock-up, and can be swapped in at the press of a button by the operator, "for urgent operation" as the manual states. "Please install those buttons at the secret area, where is most safe and operate easily" .

On the left are screen shots from the shooter, on the right from the gambling game:









It runs on bishjan.c hardware, i.e. uses the second installment of Subsino's tilemap chips. But I had to add support for dynamic tile sizes, and slightly fix the row scroll handling. There are some issues with the graphics still, as some rogue tiles are left on screen from time to time. The weird mirroring of video RAM, or the hacky IRQ emulation of the AM188-EM CPU may be the cause.

Thanks to Bicycle Repair Man.
