And, also what Files may be important when playing a computer game. So, I shall compile an list of these file types; and what Emulator would be the best to Emulate the Rom Image file.

[Note1: PS1: pSX Emulator or ePSXe Emulator, use this BIOS: scph1001.bin (or scph101.bin)]
[Note2: PS2:  PCSX2 Emulator, use this BIOS file: scph39000.bin] (It is against the Law to "Hotlink" to or "Host" a Sony PlayStation BIOS file on your site, You just have to Google the "File name" yourself)
[Note3: NDS: the DeSmuME Emulator or the No$GBA Emulator or the iDeaS Emulator, use these BIOS files: arm7.bin or arm9.bin] (It is also against the Law to "Hotlink" to or "Host" a Nintendo DS BIOS file on your site, You just have to Google the "File name" yourself)  
[Note4: Almost All of the File Extension information was found on The Central File Extension Registry: FileInfo.com]
[Note5: an NVM file functions just like an PS2 BIOS File; Example: “SCPH-90001_BIOS_V18_USA_230.NVM” (Actual Current USA PS2 BIOS Filename)]
[Note6: The Office Suite “LibreOffice”, is Powered by Java; this is why it is “Cross-Platform”, So keep your Java Runtime Environment Updated]
