Atari_Force Posted November 26, 2017 Share Posted November 26, 2017 Hello, I love this game!I wonder, is there a NTSC version?Enemies move weird (sometimes): 2 Quote Link to comment Share on other sites More sharing options...
Xuel Posted November 27, 2017 Share Posted November 27, 2017 (edited) Every other frame normally starts after the VBLANK at around scanline 285 on PAL or scanline 32 on NTSC. The late frame start on NTSC delays the animation updates so they occur after the beam has already passed. That causes glitches. I tried moving the frame start so that it occurs around scanline 147 by adding a DLI and moving the tick update from VBLANK to this new DLI. That seemed to fix the glitches. twilight-world-ntsc-fix.zip Edited November 27, 2017 by Xuel 6 Quote Link to comment Share on other sites More sharing options...
Xuel Posted November 27, 2017 Share Posted November 27, 2017 Looks like with my fix, the wizards on level three still glitch and the dragon also doesn't draw in time. I'm afraid there just isn't enough off-screen compute time on NTSC to update the screen cleanly with the current rendering framework of the game. Possible solutions would be to double-buffer the screen or reorganize the code to put all of the screen updates together so they're not so spread out. 6 Quote Link to comment Share on other sites More sharing options...

Wilheim Posted December 14, 2017 Share Posted December 14, 2017 (edited) As an small contribution, here's a version distributed in my country. It has some glitches, but it's playable. Cheers!

Indeed, the patched version on the third level looks like this. The original version in PAL 2 Quote Link to comment Share on other sites More sharing options...
