Yes you are spamming :
- you ask again and again without reading answers to your previous questions.
- you ask several time in
http://neo-source.com/index.php?topic=3227.0 and were totally off-topic.
- you open several topic to ask the same
That's the very definition of spamming.
So :
- the libretro guys have been working on the X360 port of retroarch for months, there is no ETA, i guess you can follow them on twitter, and avoid spamming them too, thanks.
- if you want to patreon them for the xbox360 retroarch port, i'm sure they will be delighted.
- if you want an update to play killer instinct or mortal kombat, you'll be disappointed : they are buggy in fba standalone and totally disabled in the libretro port. Even if it was fixed and enabled in the libretro port, it wouldn't be available to platforms not compatible with c++11, and i'm pretty sure the xbox360 is one of those platforms.
