You can see the effect of some black lines on the sprite of the enemy next to Megaman in the attached image. i wish i know the name of this problem… in that way i can find some solution by myself.
this just happen on RCA, on HDMI the image (where we should see those lines) the HDMI driver (i think) handled the situation in a better way (camouflages better the problem)
This can be reproduced: RCA connection + a game with several sprites (3+ maybe) aligned
i try change configuration on Retroarch, GPU memory 128/256/384, filters, If someone know how to deal with this please help me
