mame not recognizing simultaneous button presses

[h0gg1e]

It seems pressing buttons simultaneously is not working in multiple systems (seems to be a retroarch bug thats been fixed in later versions, see link below). Not being able to simultaneously press buttons makes numerous games unplayable.

I tested this with multiple roms mame 2010 using wrestlefest and gba using astro boy.
I tested with my gpd-xd as well as my IPEGA PG-9023 gamepad and both have the same issue.

It seems the bug has been addressed and fixed in retroarch ... is it possible to update retrox with a fixed retroarch version?

skip to the end of the thread to see that this has been fixed.

Nice! This may help me save a lot of time finding the root cause.

I've applied the latest patch in that issue track. Can you try this version to see if that fixes the issue?

I tried installing this on the two android devices I have Galaxy S8 (android 7.0) and GPD XD (android 4.4.4 can't upgrade past this version). Both failed the installation. I simply downloaded the package from chrome and installed it from the downloads folder (allowing installation from alternate sources of course)

Galaxy S8 - install gives error
"App not installed the package appears to be corrupt"

GPDXD - install gives error
X App not installed

it looks like a corrupt download or upload. I re-uploaded it again, please try again from the same URL.
