Now I understand why the black bars are there in Espgaluda in 512×240 optim mode. You mentioned that 1536 is padded to 1600 with blanking but wouldn’t it be 1350 that is padded to 1600 since h.active is 450?
If Espgaluda has 224 lines, why does changing h.active from 240 to 224 cause the image to stretch and fill the full screen width?
Battle Garegga putting out no image with h.active 320 is the biggest mystery. How can I troubleshoot that?
