In light of the recent improvements to the Philips CD-i console driver in MAME, I figured I'd record a run-through of each of the four major revisions of the pub-quiz series from TAB Austria, "Quizard".
They're fairly unique in that they have an off-board microcontroller, plugged in in place of a regular controller, providing an additional button/coin-mechanics/DIP-switch interface, as well as copy protection.
Until this most recent round of fixes, Quizard 3 and Quizard 4 didn't work, but Quizard 1 and Quizard 2 are also improved in terms of audio.
In particular, Quizard 3 and Quizard 4 would tend to hang when going in-game. Quizard 4, would eventually run off the rails either when displaying quiz images, during bonus rounds, or after a game, all of which are now fixed.
Additionally, this iteration of the game includes user-selectable categories, which include an adults-only "Erotik" category, which has been blurred prior to upload for what should be obvious reasons on this platform.
