can someone tell me the best way to config epsxe?

don't get me started about Compaq..... They sold me a compaq presario 7470: amd k6-2 533, onboard sound and graphics card(shared memory shit).... no agp slot..... only 4 pci slots..... Had to buy a voodoo 3 3000 pci but worked ok....... The shitty thing is that when I bought the thing, the manual that came with it said I could upgrade the cpu which is what I wanted(an upgradeable comp)..... to an amd tbird or athlon.... well low and behold, i learned later from Compaqs own reps that I couldn't upgrade the cpu without upgrading the motherboard...... SO I say sure why not...... Then they tell me after I say "sure, a new motherboard is cool", I have to get a whole new computer case!!!!....... wtf..... Compaq sucks...... Well lets just say I went and bought my own parts from somewhere else and by myself put together my own computer....... Tbird 1gig, voodoo 5 5500 agp, 256 megs ram 133....ect...... New case and all..... My case opens from the side not from the back..... so the whole right side panel come right off and I see my whole system inside..... I keep the panel off sometimes to cool it down faster....
