When emulation began to take off, the Neo Geo was the "Holy Grail." Early emulators struggled with the system's complex memory requirements and proprietary graphics hardware. NeoRageX (originally just NeoRage, developed by the team behind the popular CPS1/CPS2 emulator, Callus) changed the game entirely. It was one of the first emulators to run Neo Geo games at full speed on the modest hardware of the late 90s, offering a level of optimization that competitors like MAME (Multiple Arcade Machine Emulator) initially struggled to match on lower-end PCs. | | "Game boots to crosshatch screen" |
