Christopher Tumber Posted May 12, 2012 Share Posted May 12, 2012 (edited) ; - Saucer is slower and comes out less frequently. ; - Shots don't turn off when invaders get low. ; - When instigators get low, houses cleared every frame (makes stability testing easier). ; - Saucer score uses authentic table (100,050,050,100,150,100,100,050,300,100,100,100,050,150,100,050) based on player shot count. ; - Saucer direction determined by player shot count. ; - Instigators speed/speedup changed (may be tweaked based on feedback). I am not currently setup to test on real hardware and this update has not been extensively stability tested. Please post if you experience anything funky (particularly roll, flicker or video glitches). Barring any tweaks to the speed or stability fixes this should be the final version (for at least as long as last time ). The only features which could be added (PAL/NTSC switch, title screen, improved display of shots) would require bankswitching and possibily substantial revision (to free up RAM) which I'm not really interested in doing.

Thomas Jentzsch Posted May 23, 2012 Share Posted May 23, 2012 How long ago since the original release? Feels like 2 years or so, but I am afraid it was much, much longer ago. Quote Link to comment Share on other sites More sharing options...

That is fine and dandy but has nothing to do with my comment, the rom is now included in the edited post (it wasn't when I posted the comment obviously) so my point was taken.

Sorry, I misread your post becuase the ROM was posted and I didn't see the page without the ROM. I thought you were asking if the ROM should be posted here. 1 Quote Link to comment Share on other sites More sharing options...
Christopher Tumber Posted May 26, 2012 Author Share Posted May 26, 2012 How long ago since the original release? Feels like 2 years or so, but I am afraid it was much, much longer ago. Now that you mention it, it's the ten year anniversary! Sorry, I misread your post becuase the ROM was posted and I didn't see the page without the ROM. I thought you were asking if the ROM should be posted here. Yeah, my bad, not familiar with this forum software and had to go back and attach the ROM after the fact.

maiki Posted November 5, 2013 Share Posted November 5, 2013 Thanks for improving Space Instigators. Especially for slowing down the saucers so that they can be hit. I now have the game in my Harmony. Quote Link to comment Share on other sites More sharing options...
keebz Posted January 18, 2019 Share Posted January 18, 2019 Sorry to bring this thread back from the dead but after I updated the bios (Beta 5) on my Harmony Cary (Encore), the original Space Instigators rom is screwed up. It still loads but bits are out of whack and you can't see the players sprite. I tried re-downloading and loading the rom with the same issues. However, SP+ plays just fine.

Thomas Jentzsch Posted January 18, 2019 Share Posted January 18, 2019 That game version does not initialize the stack pointer correctly. So, if that pointer has a different value in the new BIOS when starting the game, the game may break. Quote Link to comment Share on other sites More sharing options...
