what should i choose on this two files

so i like the game gran turismo 1 and 2and i search it here on the website and luckily i found what i am looking forso here's the little problem of minegran turismo 2 has 2 files[PSX ISO: Gran Turismo 2 Arcade Disc - USA]
[PSX ISO: Gran Turismo 2 Simulation Disc - USA]so now... what is the difference of an arcade disc compared to the simulation discand what will be the best one to emulate on Psx emulator[P.S. im thinking maybe the arcade disc is like an arcade machine ^^ hehehe and that the simulation disc is a SIMULATION hehehe ^^]

just download both of them

those are the two discs you got when you bought the original. Arcade I imagine is stuff like single races, time trials and multiplayer, whereas simulation is the more serious career mode.

thanks men it helps me a lot.... if only there are reputation here in our forums... i will surely give you one... again thanks a lot
