The most important upgrade focuses on the visual emulation engine, aiming to completely eliminate long-standing graphical rendering errors.<\/p>\n<p data-path-to-node=\"1\">You can clearly spot the precision of these rendering fixes in a couple of specific cases:<\/p>\n<ul data-path-to-node=\"2\">\n<li>\n<p data-path-to-node=\"2,0,0\"><b data-path-to-node=\"2,0,0\" data-index-in-node=\"0\">Master of the Lamps:<\/b> In the original game, when you reach the lamps, there are 8 of them, each featuring a distinct color. Version 3.1 of the emulator had a bug that reduced this palette, rendering the 8 lamps using only 4 colors. The 4.0beta completely fixes this.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"2,1,0\"><b data-path-to-node=\"2,1,0\" data-index-in-node=\"0\">Demonic Laughter (by Virus):<\/b> This demo utilizes a notoriously difficult GTIA hardware trick where one quarter of the screen runs in a completely different graphics mode than the rest by changing the video mode mid-scanline. The new emulator engine finally handles this timing perfectly and renders the effect correctly.<\/p>\n<\/li>\n<\/ul>\n<p><!--more--><\/p>\n<p data-path-to-node=\"0\">Other improvements in this release focus on upgraded sound emulation, new hard drive handling features, and general system stability.<\/p>\n<p data-path-to-node=\"1\">Unfortunately, it&#8217;s not all good news.
