What works

  • Playing the game
  • Saving the game
  • Remapping controls (keyboard and controller both)
  • Using DInput controllers (tested with DualShock 4 v2)

What does not

  • FMV cutscenes don't play at all (game simply skips them)
    • Installing the Indeo and xvid codecs (like in X4) didn't seem to have any change
  • The game can't seem to detect the ISO as its disc when mounted; using the crack on My Abandonware was necessary to run the game


  • The game can't seem to detect the ISO as its disc when mounted; using the crack on My Abandonware was necessary to run the game
    • Crack on My Abandonware website (under "Extras")

What was not tested

  • All of the levels

Hardware tested


  • GPU: Nvidia
  • Driver: proprietary

Additional Comments

  • FMV cutscenes (located in "ST0" folder) seem to use .STR format, which according to my research might be a Playstation 1 format.
    • .STR files don't play properly in VLC; there's no video output (VLC window resizing causes erratic behavior) but sound outputs perfectly.
  • Music is stored uncompressed in the "BGM" folder and can be listened to in VLC (despite the odd file extension)

"STR" files not playing in game
by Spencer Coghlin on Wednesday August 19th 2020, 21:36
The PS1 version of this game does in fact use proper STR files for it's FMVs, but that's not the case here. This version of the game actually uses AVI files for the FMVs, but they have been named with the STR extension, most likely to hide Capcom's laziness. This would also explain why the music files are just WAV files with the SE extension.

On my Linux Mint 20 installation, I'm able to open the STR files in VLC and they play flawlessly. According to VLC, their video codec is "Cinepak Video (cvid)," but installing cinepak in my Wine prefix using winetricks did not fix the issue of them not playing in game. I have no idea why your VLC couldn't play the video files, but maybe you could try making sure your VLC can play other cinepak AVIs, or try renaming the .STR files to .AVI ones.

When I used this game on my Windows 10 laptop, I was able to replace the videos with uncompressed AVI files renamed to STR ones. However, I can't do the same through this Wine installation, and it doesn't work with Xvid ones either. For this reason, I'm thinking that a codec probably isn't the cause of this issue. I'll try installing different dependencies into a Wine prefix and see if I can find a workaround.

I should probably mention that I'm running wine-staging 5.15, and my copy detects the disc just fine with no need of a crack. Also, I get random slowdowns in game even though I don't in other games through Wine, including Mega Man X4.
