Summary 05832: batrider, batriderj: A portion of the boss's ('Gob-Robo') face is missing
Description After arriving at the boss a graphic is missing from his face and appears black. Attached is a picture displaying the problem.

Here is how it should appear (japanese ver. B PCB):
Steps To Reproduce Nothing is necessary to reproduce, simply arrive at the boss to see the error.

This can be done by following this guide (

1. Select 'normal' or 'advance' course
2. Choose at least 1 Mahou character for your team
3. Completely destroy the turret at the back of the plane in the airport stage.

It is located about in the middle of the plane, where the scrolling stops. Try to take out the side parts first, then once you destroyed the main gun in the middle, the scrolling continues.

After beating Bazzcok, the regular 'Airport' boss, you will face 'Gob-Robo' (Goblin Robot), another well known boss from Mahou Daisakusen.

an inp file would help here, showing the trigger procedure (without any cheats used obviously)
(remember, must be recorded without any nvram file present, even a default one will break the recording / playback)

Attached is an input playback that gets to the problem area. I verified playback on mame 0.157 64-bit windows build.

 It is necessary to have the following dip switches enabled because you need the secret characters to unlock him and the stage edit to guarantee the airport is the 2nd stage:

"Stage Edit" - ON
"Guest Players" - ON
"Player Select" - ON

Your changes seems to have fixed the problem. I haven't encountered any other issues associated with the fix, but I've only tried batriderj and no other toaplan2 games. Thank you for your work.
