RetroFE forums

I'm gonna guess you've bitten the Windows bullet by now? Otherwise maaaybe my thread about running it on Wine/macOS could help: http://retrofe.nl/SMF/index.php?topic=455.15

Yeah, it's what I do now. Just wish I could have it done with the combined hotkey, which is probably easier to deal with from fixing the X button thing than by adding combined input feature to RetroFE. The bar you've added actually shows on fullscreen in macOS, that is, fullscreened apps in macOS display the bar when you put hover the cursor at the top. So it'd be useful at least to me from that perspective also.

I found what's going on. The stretch settings mess up the borders of the window, particularly "vertical = stretch". My monitor is 1080, if I put in say 1000, then I see the bar. I think most people can just lower the value like I said to work around it. The window adapts okay after that.

I hope you can add the ability to close it with the X button if it's not too much trouble.

Ah, that'd be so great! Thanks. I'll wait eagerly. I think you only have to make sure the maximize button is enabled. I know foobar2000 on Wine runs with native fullscreen through this trick. I believe it has to do with the way fullscreen is triggered - starting RetroFE with its own fullscreen mode vs using macOS fullscreen through a series of wrappers Windowed RetroFE > Wine > macOS. To make use of the latter, I need the program to be windowed and have that menu bar with the - / [] / X buttons. The "stretch" height/width function is already done in RetroFE, so it should adapt easily too.

Otherwise - boring stuff - I have tried a bunch of ways to get this native fullscreen to no avail:
 
Forcing windowed with DxWnd - didn't work at all
Forcing windowed with D3DWindower - didn't work at all
Running RetroFE on a Windows VM with Parallels - works, but I found no commands on cmd that would open emulators on mac. So for example, having a launcher use macOS native RetroArch.app couldn't be done, I'd instead have to use Windows RetroArch and launch both RetroFE and RetroArch on the VM, which is a whole mess.   

I think this in general could be very useful. It could help a multi-disc games for an emulator that doesn't support .m3u, or it could be games like Gran Turismo or the Arc the Lad collection on PSX which featured media discs along the main disc. You could then merge all those entries into one, and then select which you want to open from a submenu.

Thanks. I just wanted to add that I'd like to map the scrolling of the mouse's wheel up and down.

If you ever find the time, you could run a virtual machine with High Sierra and try things out. It's quite simple, I got it running following a YouTube guide on the first attempt and I didn't even know what a VM was before I started. I understand it's not a priority, but as a goal I think it'd be pretty nice for RetroFE to support all the OS.
