Just flashed my HD4350 with your new ATOM 15 app, and everything worked great ! (It's under a homemade minicab, with a scart RGB TV inside).
When I saw the rebooting process under 15kHz all way I was just like "wow", He did it !"
I don't even havve to bother to protect the TV from bad frequencies at boot.
Thanks a loooot calamity ! No more need to buy some specific hardware or graphic card to do so (I won't tell which :) )
Now I have to try new driver/Vmmaker/Arcade OSD and super resolutions. (but i dunno if super resolutions will work with some of my emus like kat5200, zsnesw (sailorsat modified) and fusion.
If they are not compatible with super resolutions, I'll focus on the groovyume solution (even if it seems not easy to configure under hyperspin/hyperlaunch).
Anyways, again, Thanks a lot for all of that Calamity !
