I played KI2 using Mame32Plus!83 but its not run smoothly, with mame config like this: Display - enforce aspect ratio on, Increase thread priority on, rotation none, frameskip auto. Advance – rendering use directdraw on, triple buffer on, switch color depth on, switch resolution on – stretch using hardware on, clean stretch auto – resolution auto (size,depth,refresh) – effect none Sound - Enable sound and sound cpu - Resample if sample doesn’t match - Sample rate 44100 - Audio latency 1 My pc spec are : - processor Barton 2500+ 512k cache memory - motherboard ecs n2u400-a - pixelview geforcefx 5200 128m 8x agp - memory kingstone 512 ddr So if I want upgrade my pc for KI2(smooth playable), what u suggestion? Thanks
