Gradius III SA-1 patch updated to 1.5!
Added 2019-05-31 04:11:21 +0000 UTCslidelljohn discovered the cause of the little lag that the game still had after beating a boss. It wasn't that the graphics dissolving effect was too heavy for SA-1, but the code was executing twice: one time on the SA-1 CPU and another time on the SNES CPU.
It was a programming error on my part because I have designed a list of functions to be executed on SA-1 CPU and another list to be executed on the SNES CPU.... I ended up putting the same function to both lists. Not just it made the code run five times slower (2.68 MHz // 10.74 MHz => 5x 10.74 MHz) but it made the graphics effect to be uploaded and downloaded to the VRAM twice, which generated graphical glitches on the top part of the screen.
And I thought it was because the game was running too fast!
But it's fixed now! :D -- this simple change was enough for fixing the issue.
Now it means the patch is finally 100% polished and there is no other known issue or slowdown instance.
