Minimig Verilog sources should be ok from Your point of view - however notice that for perfect Paula emulation You must work with sampling freq approx 1.79MHz.
Also this can be useful

btw i strongly disagree with Sinc resampling - Sinc introduce ALWAYS pre and post ringing - even if this is optimal from mathematical point of view it is also not optimal from subjective quality point of view.
