'''RAINE''' is an a source-available, multi-[[Arcade emulators|arcade emulator]].

RAINE emulates some M68705, M68000 and M68020 arcade games and is mainly focused on Taito and Jaleco games hardware; and it also derives the 6502 and z80 [https://github.com/zelurker/raine/tree/master/source cores] from [[MAME]]. It started as an experiment with the Rainbow Islands romset, dumped by Aracorn/Romlist. RAINE can emulate many more now, including new additions from Cave and other companies.

Emulating CPU's CPUs and sound chips takes quite a lot of coding time, so, like most of the current emulators, RAINE uses emulation engines already available when possible. Although this emulator is still actively updated, and is now written in platform-agnostic C code, it is largely obsolete. It is inaccurate compared to other emulators, and it lacks the correct emulation of arcade copy protection mechanisms recently implemented in [[MAME]]. However, it does have a few unique features, such as the ability to use EmuDx files (a very early texture replacement system) for a very limited number of games, and the ability to greatly speed up the Neo Geo CD drive loading speed (which runs at the correct, slow speed in MAME).
