    Can’t wait what you put into 1.0!

    Thank you so much for releasing this. It’s good to know we’ll still be able to play X-Com without much pain on modern OS’s, and finally have bugfixes and new features after all these years.

  8. Arnos

    Found a bug though, if you try to up the resolution in the options, the game crashes.

  13. Human Ktulu

    Put in sound folder a mp3 or ogg with name GMDEFEND.mp3 or GMDEFEND.ogg .
    Dont mistake to read wiki about music.

  14. X

    @No Lobster, you don’t need Steam to play it. This is just like eduke32 or zdoom, you only need some files and the originals from your CD will do just fine.

    Congratualtions everybody on your release! I’m excited to see what’s next!

  15. Morebugs

    the game crashes when I go to a touched down/crashed UFO that I didn’t immediatley go after. It says “invalid vector” or something.
    Also gets buggy with invisible aliens biting me (reapers/chrysalids). Scrolling isn’t smooth either.
    Just a few bugs to squish.

  16. Human Ktulu

    For scrolling in battlescape, you can use Midle Mouse Bouton control with inverted scroling in adv menu.

    If not, French translation isn’t correct for new menu, it’s very very perfectible

    my computer blew up and hot metal shards of glass hit my face when the game I’m difigured and one of the glass pieces hit my dog in his pink thing.

  24. Lobster

    So I’m playing the game and scrolling feels laggy. I’m running 1920×1080 and with the HQx2 thing, and that screen effect is blurrier than what I have in the UFO-Extender, which is HQ4x.

    When I play X-COM with the UFO-Extender, it runs naturally, meaning no blocky scrolling through the Battlescape. I lowered my resolution and it’s the same, so it’s part of the games setup. Blocky scroll is a major turn off for me. I’m happy with vanilla X-COM and the UFO-Extender for now until you change it for me 🙂 Also please add a HQ4x option, because I’ve tried all the other options you currently have, but they’re nowhere near as neat as HQ4x from UFO-Extender. To me, HQ4x is beautiful. Pixely is ok, but I got used to HQ4x.

    Also saw that the music that plays when you lose the mission is wrong. That really turned me off hahaha I’m so picky because I’m used to the final briefing track that plays when you win or lose. Scary track 🙂 Gonna attempt to change the track as the wiki says. Last thing, I didn’t see the radar circles around the base after setting it in place.

    Tl;dr fix the blocky scrolling and add HQ4x just as the UFO-Extender has and I’ll be happy.

  25. Fenyő

    Lobster: You can only see the radar circles around bases AFTER you pressed the R key on the keyboard.

    And there is HQ4x for OpenXcom, it’s called: “Scale4xHQ.OpenGL”
    Althought it seems very slow as 2x. 🙁
    Maybe hmaon will optimize that later to eliminate the lag.

  26. Lobsters

    Thanks for the fast reply, Fenyő. Yes it does on every option I put, that sucks ><.

    Last thing I noticed. When I scroll up, sometimes the screen won't move at all until I keep trying and then it responds, but it's not slow, just doesn't want to move up sometimes.

  27. Lobsters

    I tried playing again, but the blocky scrolling is a real pain to play so I quit and I’m back on vanilla with the UFO Extender. I love The UFO Extender 😀

    So please add the HQ4x option from the UFO-Extender ASAP!! Why not 🙂

    Lastly, fix the blocky scrolling 🙂 Make it smooth! Please tell me I’m not the only one with this issue… Please tell hmaon thank you 😉

  28. Lobsters

    Last comment for sure. I don’t know how to fix the music problem. The wrong song plays when you’re in the win or lose screen. It’s the most annoying track in the game and I don’t want to hear it when I come back to this game.
    Can someone give me step by step instructions to change the annoying track in the win/loss screen to “Final Briefing”. Thanks!

  30. Human Ktulu

    Lobsters : See message n°25 for scrolling.
    It’s work fine and better than old system scroling 🙂

    For me OpenXcom is now larger superior than vanilla game + mods = better IA, more options, better balenced …

  31. Lobsters

    Hi Human Ktulu! You mean the drag scrolling right? I tried all 3 scrolling types and they all do the same. It’s not smooth.

    I checked the most recent OXC Let’s Play and it has the same blocky scrolling 🙁

    Then I checked a Let’s Play that has the UFO-Extender installed and it was smooth and loving scrolling 🙂

    I hope it’s a bug that needs fixing! I cannot play X-COM with blocky scrolling, it must be smooth like in the UFO-Extender!

    I agree, I’ve been playing X-COM with the latest UFO-Extender before discovering OpenXcom and I’m glad to see this game getting the attention it deserves. I def can’t wait for mods!!!

    Don’t forget to tell hmaon to add my screen effect HQ4x!

  32. Fenyő

    Lobster: I think it is possible that thing you consider as “blocky scrolling”, it is possible that it’s not a scroll issue at all. I’ve also experienced that if you use OpenGL, or HQ2x, etc, then the whole game is laggy. 🙁
    It is a slow graphical issue, which needs to be fixed by hmaon. I’ll talk to him..

    If you use “-” as Display Filter, then there is no LAG at all. Please check the scroll with using that filter!

    About the music issue:
    If you want to customize music, then go to the WIKI, there is a long description there how to customize.
    And a question: Which music-pack do you use? (where you think the wrong track is played)

  33. Lobsters

    Hello again Fenyő. I did what you said, using the “-” display filter, but it’s the same blocky scrolling. The scroll goes by each block of the map. I don’t know how else to explain it. It’s not normal because I play Vanilla with UFO Extender and it scrolls smoothly without skipping a tile block at all. Am I the only one with this problem? ;_;

    My music problem is that the game plays GMMARS on the win/lose screen. So it’s not the tracks that are wrong, it’s OXC. All I did was copy GMSTORY and renamed it as GMMARS to fix this.

    I replayed just now using Human Ktulu’s advice, drag scrolling, but with inverted dragging turned on. You can see the difference between smooth and “blocky”, as I say it :). Inverted drag scrolling is much smoother, but it’s not perfectly smooth as in the UFO Extender ;_;, but it’s a start. I prefer default auto-scrolling, because I’m used to that ;_;

  34. SupSuper Post author

    To everyone having “GMDEFEND not found” or “GMENBASE not found”, you are using an old DOS version of X-COM, and need to patch it to 1.4: (don’t worry, OpenXcom still uses the original alien screams).

    @Lobsters: GMMARS is the Debriefing music (the actual Mars music is in GMNEWMAR), this is vanilla behavior, not an error. If you don’t like it you are free to replace it with another track, but it is not wrong.

    We will be looking into all the scrolling issues.

  35. Lobsters

    Thanks for your support and I did change the music, it’s greatness. I also want to be able to load more than one track like in the UFO Extender. You just separate them by Semicolon and you’re set for a variety of tracks.

    The Nightly Builds section of the OXC site is very nice, everyone should bookmark it. Seriusly
