NanoMig 020 + cache + rom loader

[Manger74]

Have manually merged NanoMig 020 + cache + rom loader but could not build the core... place & route fails... the FPGA might be full already!?

I could remove the Stereo Mix, if it helps.
Are there tricks to optimize the place & route?
Chances to free up some LE?

I guess with 020 + cache + rom loader, the NanoMig 20K will be feature complete, if it fit's at all...

Have changed the Route Option 1 > 0 and it worked... but the chip is full...
