The Apex AD-600A was the first swiss-army DVD player. Capable of playing DVDs, VCDs, MP3 CDs and various Karaoke CD formats and available for under $US 100, the Apex AD-600A would've been a steal as-is. The inclusion of the 'loophole menu' which allowed disabling Macrovision and region-based lockouts made it Geek Ambrosia.

Loophole Menu

Only Apex AD-600A's with certain BIOS firmware versions contain the loophole menu. Around March of 2000, players were manufactured without the feature in response to the MPAA's investigation.

BIOS revisions are printed on stickers affixed to the ROMs in question. Known versions include:

Dr. Joe's Apex Page! provides downloadable firmware versions and offers links to several DIY BIOS EPROM installation pages.

To access the loophole menu:

  1. Turn on your player with the empty disc tray closed.
  2. Press the 'setup' button on the remote control.
  3. Press the down button ('\/') on the remote control until PREFERENCES is highlighted.
  4. Press the 'step' button on the remote control.
  5. Press the track rewind button ('|<<') on the remote control.
  6. Press the track forward button ('>>|') on the remote control.
A configuration screen with the title, '-- LOOPHOLES --' and the caption, 'YOU SHOULD NOT BE HERE' will be displayed.
