Here is how to put the settings to put into VMMaker (I use this to generate modelines sd fine it easier):

(NOTE: Before you start make sure you select 640 x 480 resolution as that is what you will revert to otherwise you risk losing ability to view anything! I installed Teamviewer host so I could control PC in case I messed up modelines)

1) Select "Edit Settings"
2) Select "User modes" > "Edit..." (it should have ini file already for user_modes - super, if not just make a blank ini file to edit using this option) > add the following (just copy paste and then save and close):

## Amiga ##
320 x 256 @ 50.000000
320 x 512 @ 50.000000
640 x 256 @ 50.000000
640 x 512 @ 50.000000
360 x 288 @ 50.000000
360 x 576 @ 50.000000
720 x 288 @ 50.000000
720 x 576 @ 50.000000

## Desktop ##

640 x 480 @ 30.000000
640 x 480 @ 60.000000

3) Ensure "Mode table method" is set as "static"
4) Press "OK"
5) Select "Generate modes" followed by "Install modes" - the screen will go off and then on again.

This should now give you all the Amiga resolutions you need.

6) Now go to WinUAE and under "Display" make sure fullscreen resolution is set to one of the Amia ones listed above. On my TV I used 360 x 288 and it was perfect. For Hires I used 720 x 288.

8) Select centering options if needed (I don't need to on mine).

9) Line modes should be "normal"

10) Resolution option lower down can be either hires (normal) if using 720 x 288 or lores if using 360 x 288.

There is a WinUAE config which basically switches automatically between the different modes ie lores and hires but sometimes it gets it wrong lol.

Hopefully this helps get you going to enjoy the beauty of emulation at native resolution!

You can add more modelines if you wish eg for other consoles but for MAME you're better off using dynamic modelines using super resolutions...
