Dual Stick (SCPH-1110) on multitap - not working :-(

[Darth Nuno]

Hello,

I'm trying to play Galaxian3 on epsx, with 4 (FOUR) Dual Stick (SCPH-1110).

Here's what I've done :

- Configured pad 1 to 4 as 'SCPH-1150' Dual Analogue

I've started the game without the multitap option in order to verify the pads are well configured. It works, yesss! ->



As you can see, port 1 and port 2 recognize the dual stick and it plays great.

Now, let's set the multitap on port 1 and 2... because the goal here is to play at four players!

It works when I select FOUR non analogue pad, see ->



But as soon as I trying the analogue (red or green) mode, the pads disappear :-( ->



...and since here, impossible for the emulator to recognize any dual stick on any of the four ports :-(
Tried F5/F6 in every way possible, impossible for the game to recognize at last one dual stick when multitap is set :-(

(Oh, and please note that the game Galaxian3 works with 4 dual stick on the original hardware, I had that setup working fine! But for a specific project, I need to use the emulation way...)

Do you have any suggestion to help me on this?

Thanks in advance.
