Emulator screen scaling & filters..?

[Disco Devil]

Are things like SuperEagle,Hq3/4x,Super2xSal etc & screen stretching/scaling emulator options just not possible on the Pandora power wise, or is it a reluctance on the part of the devs/porters or just too much work overall to implement them?


I may be wrong, but all the emulators i have tried seem to have hardly any (if at all) of these options.


Thanks.

I did a naive implementation of hq2x in the SNES9x port. hq3x and above doesn't make any sense since the Pandora screen is only about 2x that of the SNES native anyway.


At any rate, it basically halved the framerate when active. It uses floating point operations and with proper use of NEON it could probably be made better, but I'm notoriously lazy.
