Version 2.00 test 11:

features added

• IDE: Initial SIDE emulation support.
• GTIA: SECAM support.

Author'Comment: This test release was mainly to help with SIDE development, but I wouldn't mind more testing. It does also fix a small issue with crackling on reset. SECAM currently uses the same palette as PAL. I don't know what the palette behavior is for FGTIA yet, and it's very hard to find information on SECAM Ataris. Some FAQs even say that the FGTIA was never made even though there are people that definitely have them. The reason I implemented SECAM is that there is an anomaly in the trigger handling of the FGTIA that can break software written for cartridges that can be disabled. I have some ideas about SECAM artifacting too -- notably, SECAM only broadcasts red and blue chroma on alternating scanlines like DV and unlike NTSC/PAL -- but I need confirmation from someone who's actually seen the display of a SECAM Atari.
