Hello SwiftSnips. I have deleted link for the engine from your post because engine was without the source code.

Any kind of the engines, which doesn't include the source code, not allowed -> http://outskirts.altervista.org/forum/viewtopic.php?f=4&t=1784

Thank's for the Engine SwiftShips..
But there's one problem with this build, I'm affraid..
It always crashed ( frezzed ) in the middle of it's games..
Perhaps u should recheck once more what could possibly wrong with this compiled..

Thank's in advance

A large majority of the changes were made using my phone so there probably are some improvements to be made.

Ive narrowed it down to one of the last 2 or 3 patches I added. Should be fixed soon.

I figured out 1 error when repatching Cfish, only to come up with another. Im at an impasse. Mr. RdM is going to have to do his thing.

Hi Alex, I see lots of spider tests, but no specific topic for all spider versions. Could you tell where to find last version? Thanks

Your latest compil with new Clang compiler is very fast ! Spider 1.1dT is the best Cfish compil for Android to me.
