Uberjack has posted some more news on his PSP Dev Blog today, heres the details:
Hi-res rendering (for screens 6, 7 and 80-column text) in fMSX is proving to be less useful than I assumed it would be. The difference is mostly noticeable in the detail of text in text mode 80 - except for the occasional absence of jaggies, the difference in modes 6 and 7 is almost indiscernible - see example below:
High resolution rendering demo (both images are rendered 4:3 scaled) - to the left are low-res images (alternating columns are drawn, for a horizontal resolution of 256 pixels); high-res equivalents are to the right (horizontal resolution of 512 pixels, pre-scaling).Screen 7 images are at the top, text 80 at the bottom.
Of course, there is an added performance hit - the emulator can no longer maintain 60 fps during the hi-res modes at 222 MHz with vertical blanking enabled (it can at 266, however).
At this point, hi-res rendering is most likely to be optional, and disabled by default.
