Marvel vs. Capcom: Clash of Super Heroes (PlayStation)

Marvel vs. Capcom: Clash of Super Heroes is a port of the arcade original with several differences compared to it and the Dreamcast port, such as significantly fewer sprite frames due to the PlayStation's limited memory.

Unused Flash Mode#

Similar to the arcade version, Capcom intended to include a flashing effect in the PlayStation versions, as well as other particle effects. By default it is disabled, but players originally had the option to enable it on the option screen, before they decided to remove it as an option altogether. The option was likely removed out of consideration to the Pokemon shock incident in Japan just a couple of years prior. Certain Capcom games following that incident would include on-screen warnings for players to brighten their room for flashing lights, including Mega Man X5.

Watch on YouTubeThe option to enable it exists in the Japanese pre-release demo (SLPM-80508) of the game (which could be considered a prototype due to the fact the game was still working on it). Using a GameShark code the inaccessible option screen can be accessed and the flash mode can be enabled. Then the game looks closer to the arcade version by adding more effects and screen flashing.

The image that appears after Flash Mode is enabled. The image exists in all PlayStation versions even though it goes unused.

"If the FLASH option is set to ON, screen blinks and flash effects will be enabled. In very rare cases, such as during strong flashes, epileptic seizures may occur. There are people who have these symptoms. If this happens to you, we recommend that you leave this option OFF."

This is an alternative image featuring Hulk and Roll giving the player info about the Flash Mode, but it goes completely unused even after the option is enabled in the demo version. It looks like Capcom decided to use their Chun-Li/Spiderman version instead and left this image in the game files. From this it looks like Capcom were going to give a warning (on page 18) about flashing lights in the printed manual as well. This unused image also exists in all PlayStation versions (it even exists in the demo version).

"When the FLASH option is set to ON, particle and flash effects will be enabled. The intense flashes with this mode enabled may cause rare health issues such as epileptic seizures or loss of consciousness. If you had suffered from these symptoms, and if you want to play without these effects, you can set the option to OFF. We recommend carefully reading the description of the FLASH setting on the page 18 of the game's manual."

Demo Version Splash Screen#

A leftover from the Japanese demo version, it still exists in all retail versions.
