I know, didnt say so because the machine in question was the Dreamcast. The Saturn ports of Model 2 stuff are pretty decent from what I remember, but they certainly aint near-perfect substitutes for the real thing like the identical hardware ST-V to Saturn and Naiomi to DC ports were.
On the topic of system requirements, ElSemi mentioned on the RG board today that the Model 2 emulator runs decent on his P3-1.4 GF2MX. Fingers crossed he puts it in a seperate emulator rather then integrating it into Nebula, I dont think even Model 2 could make me endure that godawful interface. Belmont mentioned on the MAME board that the Sys21 driver runs with 3 or 4 Frameskip on his P4-2.0, not bad considering the amount of gear that system is packing.
Makes me bloody glad that i'm going to be building a new PC with XP2000+ processor and a GF4MX card in a couple of months.
