Converted the “unknown” Tetris set to the Filetto (now pcxt.c) driver,it runs perfectly with some small gfx issues (and popped up it’s actually a PC XT with a S3 video card attached to it). Korean bootleg of Tetris? (see snap two,this is 1988-ish)

Anyway,the site host have reorganized some stuff there,so you should change your bookmarks to https://mamedev.emulab.it/kale/ and your rss to https://mamedev.emulab.it/kale/?feed=rss2 ,sorry for this inconvenient but it was necessary for some reasons…

*edit* fixed color attributes in text mode & colors in bitmap mode in the driver:
