In the 31-second demo, the difference is now down to just 1\u20132 FPS.<br \/>\n&#8211; Being able to get it synchronized with the real hardware is pretty impressive in itself, I think.<br \/>\n&#8211; As for MAME, I think we\u2019ll have to put that on hold for now and come back to it later.<\/p>\n<p>&nbsp;<\/p>\n<p>1. Fixed the issue where the screen at the bottom of Moon Lake in \u00ab\u00a0Evil Son\u00a0\u00bb would become corrupted.<br \/>\n   &#8211; The problem was that a tiled ROZ size code of 0 on the UM6618 was incorrectly interpreted as 32&#215;32.<br \/>\n   &#8211; The correct behavior is 8&#215;8, with a total of 64 map entries. The old version would read past the end of the map and incorrectly interpret the following graphics data as map data.<br \/>\n   &#8211; The correct fixed 32&#215;32 special case used by the BIOS one-bit startup screen is still preserved.<br \/>\n2. Fixed the palette page calculation for non-8bpp ROZ in \u00ab\u00a0The Gambling King\u00a0\u00bb.<br \/>\n   &#8211; The ROZ color field always selects a 16-color palette page.<br \/>\n   &#8211; After the fix, a lower graphics bit depth will no longer cause the wrong color page to be selected.<br \/>\n3. The fixes are implemented as global hardware behavior.<br \/>\n   &#8211; There are no special cases based on game name, ROM hash, or game content.<br \/>\n   &#8211; No game data has been modified or included.<br \/>\n4. Game speed is now almost exactly the same as on the original hardware.<br \/>\n&#8211; If no further issues are found, this should be the final A&rsquo;can-related fix.<br \/>\n&#8211; Later today, friends in the subscriber area will first help test Chinese language support for Hero Chronicle and Dragon Quest V.<br \/>\n&#8211; The initial work like this always takes more time and progresses more slowly.<br \/>\nAfter that, things will move much faster.<br \/>\n&#8211; Once everything is confirmed to be working correctly, it will be made publicly available to everyone.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p class=\"p_telecharger_icone_zip\"><p class=\"p_telecharger_icone_zip\"><a class=\"telecharger_icone_zip\" href=\"https:\/\/www.emu-france.com\/?wpfb_dl=8394\" title=\"Download Bcan\">T\u00e9l\u00e9charger Bcan v0.08e (1.3 Mo)<\/a><\/p><\/p>\n<p class=\"p_site_officiel\"><a class=\"site_officiel\" href=\"https:\/\/www.facebook.com\/profile.php?id=61579382638861#\" target=\"_blank\" rel=\"noopener\">Site Officiel<\/a><\/p>\n<p class=\"p_en_savoir_plus\"><a class=\"en_savoir_plus\" href=\"https:\/\/www.emu-france.com\/emulateurs\/5-consoles-de-salon\/362-dunhuang-technology-super-a-can\/\">En savoir plus&#8230;<\/a><\/p>\n<div class=\"fcbkbttn_buttons_block\" id=\"fcbkbttn_left\"><div class=\"fb-share-button  \" data-href=\"https:\/\/www.emu-france.com\/?p=136937\" data-type=\"button_count\" data-size=\"small\"><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>B&rsquo;can est un \u00e9mulateur de la console ta\u00efwanaise Super A&rsquo;Can, d\u00e9velopp\u00e9 par BillyJr et bas\u00e9 sur MAME 0.287. &nbsp; Le projet reprend l\u2019\u00e9mulation existante de la Super A&rsquo;Can et vise \u00e0 corriger les probl\u00e8mes encore pr\u00e9sents, notamment au niveau de &#8230;<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[1],"tags":[],"class_list":["post-136937","post","type-post","status-publish","format-standard","hentry","category-par-defaut","uentry","postonpage-1","odd","post-author-Jets"],"jetpack_publicize_connections":[],"jetpack_shortlink":"https:\/\/wp.me\/pKi2R-zCF","jetpack_likes_enabled":false,"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/posts\/136937","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=136937"}],"version-history":[{"count":2,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/posts\/136937\/revisions"}],"predecessor-version":[{"id":136939,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=\/wp\/v2\/posts\/136937\/revisions\/136939"}],"wp:attachment":[{"href":"https:\/\/www.emu-france.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=136937"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=136937"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.emu-france.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=136937"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
