I wrote an advanced effect for STE. A real torture for the shifter
I wrote it on my 520 STE, with a motherboard made in 1989 (socketed chips).
It works under Steem, with some minor differences due to shifter timings emulation.
But when I run it on my 1040 STE, but with a motherboard made in 1991 (soldered chips), the screen is black !
So, it seems the shifter (or another chip ?) was upgraded and works in a different manner
Can someone tell me more about the differences ?
(Also, i noticied a hole in the new motherboard, where there is a socketed chip in the old one, what chip is missing ?)
