Mfme Roms: [portable]

In the late 80s and 90s, arcade manufacturers like Capcom and Atari feared piracy. So they installed "suicide batteries"—a lithium cell soldered directly to the CPU. If that battery died, the CPU lost voltage and immediately erased its own decryption key. The board became a brick. Forever.

Every red entry in MAME is a eulogy. It is a game that exists in reality—you can go to an arcade museum and play it on original hardware—but in the digital realm, it is Schrodinger's ROM. It is simultaneously saved (the bits are dumped) and extinct (no CPU can interpret them correctly). We chase the "Complete ROM Set" (MAME 0.270, 90GB of zips). We obsess over "1G1R" (One Game, One ROM) scripts to delete the bootlegs, the prototypes, the bad dumps. mfme roms

Play your ROMs. But know that you are a necromancer. And every time you press "Coin," you are feeding a ghost. In the late 80s and 90s, arcade manufacturers

You delete the bootleg Street Fighter II where Ken has blonde fireballs because the hacker didn't have the palette table. You delete the prototype Marvel vs. Capcom where the character select screen is a debug grid. You delete the Korean King of Fighters 97 where the blood is turned into gray sweat because of censorship laws. The board became a brick

MAME devs didn't just crack the encryption. They reverse-engineered the parasitic timing of the dying battery. They realized that if you emulate the decay curve of a battery losing 0.01 volts per year, you can trick the emulated CPU into decrypting itself.

But by curating a "clean" set, you are deleting history.
