Magic Dragon is a side-scrolling shoot-em-up by Magicseries. It is heavily inspired by Irem's R-Type.
Here are Disch's original notes:

Example Game:
--------------------------
Magic Dragon
Registers:
---------------------------
I do not know whether or not this mapper suffers from bus conflicts. Use caution!
$8000-FFFF: [PPPP PPP.]
[CCCC CCCC]
P = Selects 32k PRG @ $8000
C = Selects 8k CHR @ $0000
This is very strange. Bits 1-7 seem to be used by both CHR and PRG.
FCEUX implements only the bottom 3 bits of the unified register.
