Subject: [stella] Use of the Bit 1 of VBLANK - What about Overscan ? From: Christian Bogey <khryssun@xxxxxxxx> Date: Mon, 12 Apr 2004 15:51:42 +0200 (CEST) |
Hi, Regarding the Stella Programer's Guide, it's said Bit 1 of VBLANK must be set to 1 at the begining of the Vertical Blank Period (to disable the TIA output) and set to 0 after 37 scanlines (to enable the TIA output). Is it necessary to to the same thing for the overscan period ? Yahoo! Mail : votre e-mail personnel et gratuit qui vous suit partout ! Créez votre Yahoo!
