REQ: anyone have old 4.2.2 builds of Dirty Unicorns or PacMan ROMs they could share?

hi all... subject pretty much says it all, looking for copies of old 4.2.2 Dirty Unicorn or PAC Man ROMs? i just can't seem to like my Manta running current ROMs anymore, it just feels too laggy... i remember being really pleased w/ it when running DU or PM back then, but neither site offers historical ROMs that old anymore. if anyone has them and can share somehow i'd appreciate it, or any other old builds that you have found to be favorites on your manta... i'm a pretty big fan of being above to run in true tablet mode for what its worth. thanks in advance all..
