My labtop and a pentium processor, first one, its really slow, but is there any emulator that will run well on it ?

If you're looking for GB or GBC emulators, then emulators like TGB Dual would work easily. If you're looking for SNES emulators, then SNes9x or ZSNES should work although the performance might be bad. However, emulators for GBA, N64, PS, and any later consoles would not work.
