linear resample audio on sega genesis vs no resample quality

[Chilly Willy]

interpolation gives the same effect as lowering sample rate, except for the really intensive methods like sinc and the like

No, I think what he's doing is raising the sample rate, and interpolating the new samples. For example, double the sample rate, but instead of outputting the same sample twice, you output a sample between the current and the next instead.

That is exactly what I am doing I have a sample stored at 6000hz and my program will draw a line between the two samples I included the source code in the zip file if anybody is interested in how this all works it is 68kpcm.asm that has the interpolation code.

Yeah, you're basically doing linear interpolation and i agree with tmee that it actually make the sample sound at lower rate than without interpolation as you eliminate some high frequencies with that interpolation...
