Armored core - no split screen option

SIO1API

Thank you very much for quick response, I will try just that.
If I understand correctly, by enabling link cable support, the game will, in theory detect that there is no link,
and switch to split screen instead?

That's my theory

Unfortunately, it didn't work. But I wonder, if support for cable link plugin exists, where is said plugin and how to configure it?
Plugins directory reveals nothing related to SIO1, and in libpcsxcore directory, sio classes are responsible for memory cards.
By searching for SIO1API, I have found thread, where plugin named bladesio1 is mentioned.
Further searching for that, there is iCatButler's fork of pcsxr, where we have plugins bladesio1 and nullsio1.
So far any additional poking with the code has resulted in emulator crashing, but not giving up yet ;)

@matcr you might want to open an issue about this on https://github.com/libretro/pcsx_rearmed/issues

@barbudreadmon Thank you, I will.

Update:
Split screen works on Windows10 with pcsxr - 1.9.93, bladesio1 plugin is present, then disabled. Without it at all, game behaves like on pi. Unfortunately, I have no idea how to include it into complie path for raspberry build.
Here is source for pcsxr with bladesio1 plugin included:

@matcr you should add this information to the issue you opened, it might help fixing it.

WOAW incredible if it is possible to play with it one day <3
Like i dream to use this option from many years on all the portable consoles, GB, GBA, GG ... to play games in two player mode on one TV ... but no one never add this to these emulators ... :(
I'm sure it is possible on PI3 to play with two GB at same time, and if you say it is possible for PSX too it is incredible ???

lr-tgbdual allows this.

You misunderstood the topic, actually the OP want to use the split screen mode on 1 console available for this game.

It is possible for any emulator to do this, the main principle is to run 2 instances of the machine, and emulating the link cable between those 2 instances, however :

most of the time, the emulator will need heavy rewriting to isolate both instances from each other (or the 2 instances would interfere with each other)
that means you emulate the machine twice, so gba or psx with link cable support is a no-go on rpi3 performance-wise.
it needs an accurate documentation on the link cable, which is not something you'll find easily for all systems (actually i looked into this for neogeo pocket some time ago, but couldn't find any documentation)

Thanks for your answer :)

Yes i know this, it's logic :)

Ok yes, it is a hard work :(

Yes it's what i think, maybe GB can work fine ... or on Odroid ...

Yes it's always the same problem. Or you must make some reverse engineering, but it is really a hard work :(

Its not hard. You just have to hold R2 at the title screen, and the link word will go away. Making it possible to play split screen. Have 2 controllers setup. Hold R2 with player 1 controller at title screen. Link will disappear. I just did it.
