I think you found this "scantripling" information in Natami forum? If they are able to implement this, it may not be possible that easy for Minimig. The FPGA is quite full and perhaps the basic timing need to be changed... I did not find any good information about scantripling or how to realize.
I have tried scan-tripling and quadrupling a long time ago.
The one I prefer is the scan-quadrupling because I can easily map 320x256 or 640x256 to 1280x1024 native resolution.
As a result, there is no blur on an LCD screen.
Moreover, with a smart dithering, you can simulate 1 million colors with a 12-bit RGB output.
Scan quadrupling is NTSC only because in PAL : 312 x 4 lines = 1248 lines, the screen thinks that you want to display a 1600x1200 image instead of 1280x1024.
