The main drawback to going with an ASIC is the initial costs are much higher than an FPGA. If you can sell high volumes of a chip, this initial cost can be spread out without damaging the affordability of the chip, so what works out as cheapest depends on the number of units you can sell. Just in case you weren't aware, there's already a C64 SoC (a C64 in a single ASIC), that was designed by Jeri Ellsworth for the C64DTV. It's not got the processing power of the C65 but it does have the capability to run most/all C64 software. https://en.m.wikipedia.org/wiki/C64_Direct-to-TV https://en.m.wikipedia.org/wiki/C64_Direct-to-TV
