Over the next few weeks, will post more detailed information about the copy protection scheme of the CPS2 board, but the proof-of-concept works right now. With a security key kept in battery-backed memory, this was enough to keep the code for the game secret, albeit at the cost of preventing historical preservation. In the Kabuki hardware, the on-chip ROM was interspersed with a few XOR gates on the processor’s bus.

Last year, reverse engineered the on-chip security for Capcom’s Kabuki processor, the CPU used in some of Capcom’s earlier arcade boards. The code that does the trick is up on GitHub. Unfortunately for future generations, Capcom took some short-sighted security measures to prevent copying the games, and the boards have been failing over the last two decades.Īfter months of work, and several other arcade enthusiasts have reverse engineered the security protocol and devised a method of de-suiciding these arcade boards, allowing for the preservation of this hardware and these games. As you would expect, these boards have become collectors items. Predator, and a few of the Marvel and Capcom crossover arcade games. Posted in classic hacks, Slider Tagged apple, Apple 2, apple II, ProDOSĬapcom’s CPS2 – or CP System II – was the early to mid-90s arcade hardware famous for Super Street Fighter II, Alien vs. Since you’re probably not downloading directly to an Apple II disk, grab ADTPro and load it over audio.

#BITBURNER THE CAVE ARCHIVE#
A few utilities are also included on the ProDOS 2.4 disk image including ADTPro, Shrinkit archive expander, and disk utilities.Ī 140k ProDOS 2.4 disk image is available on ’s site and on. Think of this as the Norton Commander of the Apple II ecosystem, allowing slots to be selected, booting the most recently used ProDOS device, and basic file system exploration.

The killer feature and one more thing of this release is the BitsyBye utility, a small ( $300!) system program that allows you to boot various Apple II devices and programs. Older machines aren’t left out, and ProDOS includes the usual features and improvements found in ProDOS 2.x that weren’t available in the Apple ][+ and un-enhanced Apple //e. These features include enhanced utility in GS/OS – the Apple equivalent of the Commodore GEOS – slot remapping, and an OS that is both smaller and loads faster. New features abound, although most of them are geared toward the now thirty-year-old Apple IIGS.
#BITBURNER THE CAVE DRIVER#
This release is the most important development in the Apple ][ as a daily driver agrees, and ProDOS 2.4 is now enshrined in The Archive for all eternity. ’s release of ProDOS 2.4 fixes all of this.
#BITBURNER THE CAVE UPDATE#
This swan song of the Apple II platform is simply ProDOS 2.4, an update to the last version of Apple’s ProDOS, last released in 1993.įor a bit of historical context, ProDOS was not the operating system that shipped with the Apple ][, even the latest version of ProDOS is horribly out of date. It is, without a doubt, the greatest release the Apple II platform will see for the next few years. Although this sort of work is usually reserved for KansasFest and other forums for highly technical and very skilled Apple enthusiasts, ’s release of a new version of the ProDOS operating system is no less important.
