The earlier Capcom system board, the original CP System or CPS-1while successful, was very vulnerable to bootleggers making unauthorized copies of the games. In order to rectify the situation, Capcom took the CP System hardware with QSound with minimal changes and employed encryption on the program ROMs to prevent software piracy.

Due to the encryption, the system was never bootlegged until unencrypted program data became available. The relationship between the A and B board is basically the same as that between a home video game console and cartridge.

The exception to this is that the blue and green boards can be used together. The B boards hold battery-backed memory containing decryption keys needed for the games to run. As time passes, these batteries lose their charge and the games stop functioning, because the CPU cannot execute any code without the decryption keys. This is known to hobbyists as the "suicide battery". It is possible to bypass the original battery and swap it out with a new one [1] in-circuit, but this must be done before the original falls below 2V or the keys will be lost.

Consequently, the board would just die anyway, meaning even if used legally it would not play after a finite amount of time Unless a fee was paid to Capcom to replace it. Due to the heavy encryption, it was believed for a long time that CP System II emulation was next to impossible.

However, in Januarythe CPS-2 Shock group [2] was able to obtain unencrypted program data by hacking into the hardware, which they distributed as XOR difference tables to produce the unencrypted data from the original ROM images, making emulation possible, as well as restoring cartridges that had been erased because of the suicide system.

In Januarythe encryption method was fully reverse-engineered by Andreas Naive and Nicola Salmoria. It has been determined that the encryption employs two four-round Feistel ciphers with a bit key. In AprilEduardo Cruz, Artemio Urbina and Ian Court announced the successful reverse engineering of Capcom's CP System 2 security programming, enabling the clean "de-suicide" and restoration of any dead games without hardware modifications, as well as disabling the suicide routine of the board altogether.

These additions might've been led by the belief it becomes fair game to share after more than a year passed after the expiration of commercial exploitation on the original machine.

Additionally, as the ROMs are essentially the same whenever they have been archived, other than absent ownership controls, whether its archived now or later will make little difference.

The mame licence only specifies that mame cannot be distributed with roms included i.

Mame itself has always been legal, emulators are legal. Some countries may find what archive. When did it start?

It came to mamedev's attention only about a week ago, but no rules or conditions are being broken. An exploitation of a gray area in U. Oh, then can you say where it was?

They include every single CPS-2 game and hack. This will save people from having to scour the forums to find everything. I'll update my lists whenever new content is available. Extract a pack to it using 7-Zip, maintaining the folder structure. The current pack is for users with the latest firmware, who have wired their kit to support key writing. The "Old" set is for old firmware users and is no longer updated. Troubleshooting The most common kit problem is SD card incompatibility. Test multiple cards before reporting problems, especially if they are larger than 4GB.

Format only as described above. Format the SD card every time you update your pack, before copying new files to it. This prevents corruption and alphabetizes the game list. Format and re-copy everything, every time. It can also mean that your microSD isn't compatible or needs to be formatted correctly. Thanks PascalP! A huge thanks to Darksoft and Company for the key-writing functionality.

This will not receive updates. Folder link unavailable so sayeth Mega. Can't access it. Get ToS'd that quickly? Or copy wrong link somehow? I think that the url was just wrong. Working now? Awesome job! Now where do I download that label? My Multicart labels for sale here: arcade-projects. Awesome Sauce! Hey are the names.

This is awesome, thanks! Nice work, thanks! I should ask, just to make sure.

Does this have the Rockman 2 fix on it? Downloaded but hadn't pulled my kit from the cab yet to copy the files over yet. Literally just copied the files over the my SD card :.

After a near death experience, the loss of the original Omnitrix and the acquisition of the Ultimatrix Jen is ready for life to settle down to as normal as it ever gets. Her world is once again turned on its ear though when the world catches wind of her secret identity. With her private life made very much public Jen will have to wrestle with enemies old and new while working out how to control the Ultimatrix and heal from the worst kind of broken heart.

After Ben Tennyson is sucked through a portal, he ends up in a world different then hsi own. However, his luck begins to turn when he meets three teenagers. As Ben begins to know more aobut the world, an evil organization is hellbent on capturing the horned girl.

And now the Omnitrix wielder will find himself fighting for his and his new friend's life. All the while digging into the history of the horned girl and the conspiracy behind the organization. The Tennysons aren't strangers to difficulty. They've fought Warlords and mercenaries and just plain creeps, on off since they were But when there's an accident in Azmuth's laboratory, the Tennysons find them selves in situation they never been in before: alone.

They've fallen through multi-verse to an fun house mirror version of Earth, the land, history and people familiar but twisted and distorted beyond recognition.

Not necessarily evil, just different and definitely not welcoming of a pair of teenagers that break the unspoken divides between the human and monsters.

This is a tale focused on the subversion of multiple super powered males from various settings and the going ons thereof. It will have a plot and I'll attempt to write everyone in character.

Comments and reviews are welcome, even suggestions of where the story can go.
