MarsSeed [1] filed a deletion request for shmupmametgm-git [2]: This is a now deprecated VCS package for a customized MAME emulator fork. Code development discontinued in 2020. Its GitHub repo is inactivated (archived), so it's read-only and even the issue tracker is frozen in time. There are no continuation forks available. Safe to delete. Nothing requires this package.
