Title: pdaXrom on c series -- but use 320x240 hardware ..
Post by: ScottYelich on October 12, 2004, 03:03:34 pm

Hi -- I tried searching, but I didn't get any search results.
If anyone can search and find anything, please let me know what you did to
search --

I'm wondering -- is it possible to launch a program with pdaXrom that changes the screen res to 320x240 -- is ther hardware acceleration to do this?

The idea would be to run mame in that mode, vs using the scale2x which is VERY
slow..  or the mixed/fractional (ie: -output fullscreen) which is even slower.

Something like:

Code: [Select]

xrandr -s 320x240
should work for you.  If you want to run something like, say, quake:

Code: [Select]

xrandr -s 320x240 && quake && xrandr -s 640x480
This will bring it back to VGA after you quit...

Code: [Select]

xrandr -s 0
xrandr -s 1
will do the same magic :-)

ah, ok.
I don't have mame (advmame) source handy... I'm still running it under 1.0.1

I'm flashing rc5 now.... having some troubles.

ps/edit:  ok, seems to like the 46mb root on the c700

DGen sources for sonic on our beloved zaurus... worked on Sharp rom without framebuffer, will be a lot faster with virtual float. and direct rendering
