Ok, I overestimated the size of the lookup texture. I've now implemented the hq2x algorithm and it runs at a pretty favourable frame rate. Are the developers interested in merging this? If so, which version of xmame would you like me to diff against? On Wed, 15 Dec 2004 15:01:47 +, Matthew

Is this for nvidea cards only or should this also work on ATI cards? I used the ARB extensions so it should work on all cards supporting fragment programs. About the effects in opengl mode, could you make it work like the Xv driver? (-video-mode 1) This one uses for example scale2x or scale3x
