Yeah, would be extra great to eliminate the 6502 emulation in FPGA, and put a 14Mhz 65816 on the board. There would be a ton of extra gates left (that the 6502 emu took) to add extra hardware, like clock card, echo card, parallel port, serial port, Z80 card, extra RAM, RGB output, etc etc.
I expect that the 6502 implementation on the FPGA uses a very minor part of the chips resources. There is no reason to use a slow, big, expensive, separate chip to do what can easily fit in a corner of an FPGA. -michael 8-voice music synthesizer using NadaNet networking!
