    Background:
    I found this a massive problem. I would use popstation to convert my spyro one to an eboot and it only compressed it to about 420mb. And with crash bandicoot is was 500mb. So I started searching around and I finally found a way to compress a ps1 game by ripping the videos and audio. I tried ripping them first manually but the game just kept crashing. So i found the programs.

    Step 1: download magic iso. it has to be a cd ripper that can output the cd image as a bin file.

    step 2: If you have the original CD select image file from cd drive
    If you have a psx iso select iso to bin

    step 3: download PSmplay.

    Step 4: run the program and under the file menu select "analyze DAO image"

    step 5:select only these two boxes

    step 6: once the analysis is complete it will ask if you want to save the "psm" data. press yes and save it in the same directory as the bin file.

    step 7: download PSXLDR

    step 8:run the program and open the psm data you just saved. Then (without closing the program) open the Bin image.

    step 9: on the left hand size select rip all. (it may not look like it's doing anything but just be patient. It could take upto 10 minutes.)

    Step 10: done! even though the bin file will not appear any smaller it actually is. Because it has ripped all the music and videos out of the archived video files.

    Step 11 (optional): you'll notice the difference in size when you convert the bin file into an eboot using popstation. Spyro the dragon is now down from 420mb to 170mb.

    I too am curious if this means that all the videos/cut scenes are missing from the game, or just compressed differently.

    You simply cannot compress videos to such extents. Try archiving an AVI or an MP3 ! lol

    (WinRAR, 7-Zip, KBG Archiver).

    Yo blaze
    I tried that about 6 times already and can't seem to get the same results you did. Of course I'm doing this with other games, but you put down PS1 ISOs so I assumed it'd work with any game for the PS1. Everything is still fairly large. And I think the magic ISO link you gave is a different version from the one in the pictures.

    sorry for the late replies but yes it does rip videos, and music. Not sure what game youre trying to rip it with but it will only work if you have a game with lots of music/videos.

    So what you're saying is that if the game itself has no videos, like Breath of Fire 3, then there is no effect. While if the game has plenty of videos, like Final Fantasy 7, Xenogears, Lunar, and Chrono Cross, there would be a more drastic effect. Is that the gist of it?
