I'm trying to use an older laptop for an arcade. It's a HP G60 with an AMD Athlon X2 QL-64 @ 2.1 ghz, 3 GB of ddr2, and an Nvidia Geforce 8200 m graphics adapter. I tried to run Mortal Kombat and Street Fighter for Snes and Genesis and both are super slow. The run just fine using RetroArch through the Windows Vista 32 Bit OS. Any suggestions?
