Development packages track the latest successfully built master commit,
not a permanent version tag. They may be less stable than tagged releases,
and their downloadable assets can be replaced by newer builds.
Release archives never contain ROMs or BIOS files. Each archive includes CPS1, CPS2, MVS, and NCDZ builds for the selected host. Desktop downloads are split by operating system because native executables are not cross-platform.
Browser tool
MVS/CPS2 ROM Converter
The existing browser-based converter remains available for creating the processed/cache assets used by supported MVS and CPS2 runtime paths. Conversion happens locally in your browser.
