Where we get the old games or computer’s firmware and copy it to ROM files on recent computers then with the help of a software that we call it “EMULATOR” we will be able to run this ROM GAME on a computer “PC”. We use this term more often related to emulators. Main board of arcade games or computer’s firmware. Simply, it is one of computer file containing a copy of certain data from a read-only chip, usually from a video game cartridge. Well to answer that, you need to know what is ROM image or ROM file. I think that I gave you a comprehensive and good idea about what is ROM, now back to our first question: what are Games Roms? ROM writing speed: for ROMs electrically modified, writing speed is always way slower than reading speed, sometimes need high voltage.

ROM reading speed of course is much different than RAM speed this is why we do copy ROM content to RAM before the first use, later we read from RAM. But this usually takes a lot of time and need special gear or hardware to establish and for few times only. Lately, ROM has been updated to enclose read-only memory in normal operation, but we can reprogram it other way.Įrasable programmable read-only memory or we can call it (EPROM) and electrically erasable programmable read-only memory or we can also call it (EEPROM), maybe it is a bit understandable by its name which we can erase and reprogram it again. Like diode matrix and mask ROM or “MROM”, which means that we cannot change it after being produced. Read only memory refers to hard wired memory. The main use of ROM is to store firmware, now you may be wondering “and what is firmware?” Let me answer you - firmware is kind of software that closely related to a specific hardware and needs updates frequently, that was the firmware short explanation now back to ROM again, as I said that the main use of it is to store firmware or application software in something called plug-in cartridges. Most of the times it is impossible to modify the data of ROM without having advanced knowledges in the IT field. ROMs GAMES or ROM which stands for (Read-Only-Memory), it is NVM or (Nonvolatile Memory) which we mainly use in many devices such as computers, mobile phones, consoles and other. At the beginning people, who had advanced knowledges in IT field started to extract ROMs from cartridges and upload them to the Internet. ROMs, Rom Games and Emulators, does it sounds unfamiliar for you? Video game ROMs are nothing else but a software which is installed on a videogame cartridge, however these days there are hundred thousand of roms available for download on the Internet.
