Well, that's nice. At least it looks like the clone FPGA is in fact a copy of the real thing, in as much the one in the older Fnirsi-1013D is the real thing..!? Most probably a development for the original Altera (Intel) FPGA will work on the Chinese clone.
Reversing the FPGA? AFAIK that is impossible.
Now I have to figure out how to get OpenOCD talking to the clone, since Quartus is not. Or maybe Quartus can be tricked?
Results so far with OpenOCD, calling the chip "sesame":

Warn : Adapter driver 'usb_blaster' did not declare which transports it allows; assuming legacy JTAG-only
Info : only one transport option; autoselect 'jtag'
Info : No lowlevel driver configured, will try them all
Info : usb blaster interface using libftdi

Warn : Bypassing JTAG setup events due to errors
Warn : gdb services need one or more targets defined
It comes up with the same chip identifier as Quartus IDE programmer, and also sees a manufacturer. Have to look further to get the chip config file for openocd working. OpenOCD is all new stuff for me.
Attached some pictures of front- and backside of my board with JTAG and ICSP connectors. I added also a RESET jumper and jumpers to freeze the FPGA nCONFIG (low) and nCE (high).
