    Final version 1.0 of Half-Life: Blue Shift comes out.

    Playing Dreamcast Half-Life: Blue Shift on ... Playstation 2:


    === WARNING ===
    Saves from previous builds are not working again as I found an option to separate Blue Shift saves from the main game so it is no longer possible to cause crash by loading save from wrong game.

    === Version 1.0 changelog ===
    - The game is completely stable now. Instabilities were caused by a bug in the game code:
    reference to every used file is stored in RAM inside special section and unused references are never cleared.
    When this file reference list goes out of bounds all sorts of crazy things can happen.
    So I made a hack that increases size of this section from ~206KiB to 512KiB
    - Added save game isolation to prevent crashes by loading saves from wrong games
    - Merged HD and SD models into one ISO and made in-game selector to choose between them
    - Added an option to play with Dreamcast models (and maps)
    - I found out that I messed up soundtrack in previous builds.
    Correct PC soundtrack would play now if you choose to play with PC models and authentic Dreamcast soundtrack
    would play if you choose to play with Dreamcast or PS2 models
    - There should be less rescaling artifacts on map textures
    - Lots of other small improvements that I forgot about

    === Known flaws ===
    - Big framerate drops in some areas
    - Wierd glass behaviour in some areas
    - PC models can cause some minor graphical glitches on PS2
    - Scientists inside intro elevator are non-solid to prevent major glitches,
    but elevator can still drain some HP from player

    ==Launch it with OPL==
    Due to the fact that today it is difficult to buy a CD with a good quality,
    so I recommend to copy the image to the "CD" directory.
    and put it on your USB drive.
    Launch it with OPL.

    Here you can find the latest OPL BETA version:
    https://akuhak.github.io/test_build/.

    The (ISO) image on the USB drive cannot be fragmented.

    This mod is from the NTSC region U\C,
    so the OPL must be started with the E1 launch keys at the cold boot.
    Because without this method there are problems with sound.

    If you have NTSC U\C console, enable PS2 logo in settings.

    i have the dreamcast one. but i will enjoy it much more on ps2. 2 analog sticks and much more faster loadings. i would like opposing force to be ported as well one day.

    Wow it seems like there has been a lot of cool stuff for the PS2 I missed from the past couple of years. By the way, it seems that you're modding the retail disc directly, but doesn't the original PS2 Half-Life have a way to load mods from separate discs (much like the official Uplink mod disc)? Have you ever looked into that?

    I also hope that you work on Opposing Force, too. Nice work!

    I'm not the developer responsible for this mod (supadupaplex is), everything is in source.

    Regardless, it's nice to see homebrew like this being made. :)
