internal flash ( i can use it with other devices using another pins as SS ) and another one on pins 12,13,14,15.

Honestly I don't know enough about it. I did think that a SD card in 4 bit mode might work (what I was interested in) but the information I read about it eliminated that possibility. https://github.com/esp8266/Arduino/issues/4298

Do some searches on HSPI and see what you find.

article on freeing gpio9/10 this ofcourse works on ESP-12 also once cap is removed...

Sweet, I didn't know that; thanks @schufti, I'll keep that in mind when struggling with not having enough I/O again.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
