I think those two only stretch horizontal (vertically they are still 1:1 w/software scale) because the size is so close up/down so that is why they can get away with averaging horizontally only. You would have to do it both ways in GBA emulation or it would look blocky (and squished) one way.slaanesh said:With the recently release of the CPS2emu and now Picodrive both featuring pixel averaged rendering of the final display, do you think this is an option for gpSP? I believe that these only average pixels in one direction - horizontally - which is why it's fast to do.
There are a few systems that can use this horiz only averaging though. Doesn't seem to kill performance alot. NES, SNES (probably still too slow?), PC-engine. For those that like the "TV look" horiz only averaging kind of looks like that. TVs would tend to blur horizontal but be sharp vertically (scan-lines were sharp and didn't blur into each other).
BTW: Congratulations to Exophase on making guru You deserve it.
The emu runs pretty smooth now, even for me.
