you're right that tgmame is not an official version, but it's more official to marp and the competative spirit than the original official version.(posted 9063 days ago)I welcome any unofficial version that creates recordings that ALWAYS playback with an official version. Case in point: the pentium optimized versions seem to be living up to that. However, strechmame is unproven since we can only be certain of this untill the official one comes out...
already you can't get strech mame by clicking the "getmame" version and i doubt you'll be able to download strech mame through the link once the official version gets put in it's place.
