Out of memory screen display on system running Debian 12 (Linux kernel 6.1.0-28). Out of memory (OOM) is an often undesired state of computer operation where no additional memory can be allocated for use by programs or the operating system.
In some cases, emulators allow for the application of ROM patches which update the ROM or BIOS dump to fix incompatibilities with newer platforms or change aspects of the game itself. The emulator subsequently uses the BIOS dump to mimic the hardware while the ROM dump (with any patches) is used to replicate the game software. [7]
PCSX is a free and open-source, video game console emulator that allows software designed to be used with the Sony PlayStation to run on personal computers. Over the years, development changed hands several times with PCSX-Reloaded (PCSXR) now being the main version. As of 2021, the emulator seems to be no longer under active development. [5]
A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). [2] A memory leak has symptoms similar to a number of other problems and generally can only be diagnosed by a programmer with access to the program's source code.

The original IBM PC and all PCs until the early 1990s used parity checking. [12] Later ones mostly did not. An ECC-capable memory controller can generally [ a ] detect and correct errors of a single bit per word [ b ] (the unit of bus transfer), and detect (but not correct) errors of two bits per word.
