DRAGON'S LAIR ENHANCEMENT ROM SET VERSION 2.1 - 1 January 2005
Created by Dave Hallock
with Jeff Kulczycki
INTRODUCTION
Apple requires all apps to be signed with a certificate that chains to an Apple root. Since 2016, Apple has deprecated older SHA-1 certificates. An IPA from 2011 carries an expired signature. On a modern iOS device, the OS would reject it outright. On iOS 4.2.1, the device checks certificates against an anchor list from 2010—some older certificates might still be accepted if the IPA was signed with a long-expired but originally valid Apple certificate. However, if the IPA has been re-signed or cracked (a common practice on third-party sites), the signature is completely invalid, and the device will show "Application not installed."
Set up a proxy server on your local network (e.g., using mitmproxy or an old Squid config) to downgrade TLS for Messenger’s IP addresses. This is technically challenging and not recommended for average users. facebook messenger ipa for ios 4.2.1 download
For devices running legacy software like iOS 4.2.1, you generally have two paths: Apple requires all apps to be signed with
Installing Facebook Messenger on iOS 4.2.1 (primarily found on the iPhone 3G and iPod Touch 2nd Generation) is challenging because the official standalone app, launched in August 2011, quickly raised its minimum requirements to iOS 4.3 or later. Since Meta currently supports only iOS 12.4 and above, you cannot find a compatible version in the modern App Store. Technical Workarounds for Legacy Devices On a modern iOS device, the OS would reject it outright
: Even if you successfully install the app, it may fail to log in because Facebook has disabled the legacy APIs these old versions use to communicate with their servers. How can i download the facebook messenger for iphone4
(Internet Archive, Dropbox links, random forums). These are high-risk. Many files are mislabeled (e.g., "Messenger for iOS 4" turns out to be for iOS 6). Worse, malware authors love old IPAs as vectors for phishing or spyware, since modern antivirus tools rarely scan legacy formats.

DIP SWITCH SETTINGS

VERSION
DLE 2.1 replaced DLE 2.0 by compressing the software to fit onto 3 EPROMs instead of 4, and by allowing the diagnostics ROM check to pass if other game EPROMs remain in the unused sockets, and by correcting a bug with one of the death scenes.
The 2.x series of DLE resequences the game to keep similarly-themed scenes in sections. Reversible scenes only need to be completed once during one game. The DLE 2.x scene sequencing chart provides a thorough explanation.
The 2.x prototype mode plays over eight minutes of cutting room floor animation that was added to the limited edition laserdisc, with the original experimental design concepts of multiple branching and the "ACTION" button that were present in the prototype Dragon's Lair arcade game.
(The original Dragon's Lair laserdisc works with the standard game mode. The limited edition disc is not required.)
DLE 2.0 succeeded the 1.x series.
EPROMS
DLE 2.1 is a 3 EPROM set that works with any working Cinematronics Dragon's Lair game using any laserdisc player or video source.
Dragon's Lair uses type 2764 or 27C64 EPROMs or compatible, rated 250ns or faster (2764-25).
EPROMs rated slower, such as 300ns and higher (2764-30), have been reported incompatible.*
National Semiconductor brand EPROMs have been reported incompatible.*
*(These are original hardware incompatibilities, not specific to this ROM.)
DOWNLOAD
VERY IMPORTANT!!!!!
The download contains readme21.txt. This complete text file, or a printout of it, MUST accompany all distribution of DLE.
These ROMs are EXTREMELY DIFFERENT and this information is essential, with new DIP switch settings and a guide for the prototype mode, among other things.
Keep it together with the ROM files. Keep a printout with your game cabinet, including through any change of ownership. Please don't leave new owners clueless. Thank you!
