[Cho Aniki] Broken game behavior with RetroPie and RetroArch

[Spoofer451]

I just decided to load this PCE-CD game using this core and the game has broken behavior that I have not seen in emulators such as Ootake.

In the game you collect these floating guys that follow your character like an option in Gradius that shoots bullets alongside the player character.

In this core that does not seem to work and according to one post I found in the official Mednafen forums, here:
https://forum.fobby.net/index.php?t=msg&goto=4263&#msg_4263

It seems to be related to the Multitap emulation according to that but it seems like the core does not emulate the multitap so I am at a bit of a loss of what is wrong.

Here is a video of what the issue is that I just recorded so anyone reading this can get an idea of what is going on:

The muscle guy in the video SHOULD be shooting projectiles.

With the pce accurate core you have an option to disable the multitap and then the macho guys shoot.

Late response, but is there any way to access this core within RetroPie? I can't seem to find it in its current version.

took me awhile to realize Ai Chou Aniki was a different game than Cho Aniki. Thought you need to finish a stage or something.

Got the right game got it fixed (or at least have it working)

Is there a way to get this going on the current version of RetroPie? I would love to get it going there. I tried installing from the source but nothing really changed.

here is a fun "hack" you can use to play the game properly while waiting for the PR:

1: have someone on player port 2 press the attack button :D
or 2: just use the same controller (Settings > Input > Port n Controls > Device Index) from por 1 on port 2 with both the same button binds and play that way. this still works.

long story short, with multiTap disbled, your inputs are getting sent to a all 5 ports instead of each port having its own controller.

But yeah, ill be sending a pr and have this as a core option soon.

let me know it this trick works.
