GroovyMame论坛一个国外玩家，把一个笔记本240p成功了，哈哈。。。
是AMD A8 APU ，整合了AMD Radeon HD 6620G核显。。。大家可以参考一下他的安装和设置过程。。。
http://forum.arcadecontrols.com/index.php/topic,152655.0.html
是在Win10下安装Catalyst 12.6成功的，而之前安装的驱动是Crimson 16.2.1 non-GCN* cards，有问题，该驱动认出的显卡是Radeon HD 7400M。
Ok, so I made another windows 10 clean installation this morning to install Calamity drivers properly, and I can confirm that the installation shows two MS Basic Display adapters, I suposse it's an APU thing. I chose the second one and the drivers installed fine.
Then I ran VMMaker, and followed the Calamity guide steps, with an exception, my graphics card has two outputs, hdmi and vga, so I thought I had to choose "Analog_0" because the card has 1 analog output, but it seems the laptop screen counts as another analog output and choosing Analog_0 doesn't work for me. I tried with Analog_1 and worked, but the laptop screen was still the primary in my case, I connected the tv and it showed the extended laptop, so I went into windows display configuration and chose to use only the second display, and followed the rest of the guide.
果然笔记本的输出240p成功关键和主副口和主副屏幕有关。这笔记本有HDMI和VGA两个输出接口，他选择模拟口Analog_0不成功（该玩友猜测笔记本自带屏幕是占用了模拟口Analog_0），而Analog_1口成功。然而笔记本的本身自带屏幕就是primary主屏幕，通过VGA口接到电视上显示的是扩展笔记本桌面（副屏幕），于是进入windows display configuration系统显示设置，只使用第二显示屏（关闭笔记本自带主屏幕，只使用VGA口输出到CRT电视或彩监的副屏幕）才行。
猜测：该玩家装驱动时出现了HD 7400M，我估计是他笔记本的独显（也可能是驱动和系统认错）。HD 7400M系列如HD 7470M，查TechPowerUp网，是40nm的非GCN卡，装Crimson 16.2.1 non-GCN*或Catalyst 12.6有机会成功，Crimson 16.2.1 GCN*则不对该显卡。。。
他的笔记本或许有两个显示核心，一个是APU的核显HD 6620G，32nm。一个是独显HD 7400M，40nm。可能笔记本的VGA头是对应核显HD 6620G的，而独显HD 7400M装完Crimson 16.2.1 non-GCN*依然无法输出模拟信号到VGA头，也许独显HD 7400M的模拟信号是输出到模拟口Analog_0上，而Analog_0被笔记本的自带屏幕占用了，即独显HD 7400M的模拟信号输出给了笔记本屏幕，而无法输出到VGA头（Analog_1口）了
所以只能用APU的核显HD 6620G通过VGA口（Analog_1口）输出低解240p模拟信号。
或许改改设置，能让独显HD 7400M也能通过VGA口输出模拟信号。
NoteBookCheck网站正好有这个笔记本双显卡介绍。
AMD Radeon HD 6620G + HD 7450M Dual Graphics

Then I generated the modelines, but when I tried to install them a error message appeared with each of them notifying that the modeline couldn't be installed because it was rejected by the driver, so I closed VMMaker and ran it again, this time as an administrator, and this time it worked fine.
生成低解分辨率的modelines时出错，关闭VMMaker再运行它，这次成功了。
