Thanks to the always brilliant work of 'furrtek' another custom IC has been reproduced and preserved.
It's the Capcom '86S105, the sprites generator used on many PCBs like :
I made different revisions of this reproduction.The first one was based on a bootleg replacement but it was not perfect due to wrong design used by bootlegers :
The second one was a FPGA prototype based on 'furrtek' work :
The third revision of my reproduction was a single part interfaced to PCB footprint by the use of castellated half holes design :
Here's successful testing on a Pang PCB :
The fourth and latest one , always FPGA and 'furtek' work based, is a two part reproduction with a top board that plugs on onto a bottom board (soldered on game PCB always by castellated half holes) :
Successful testing on a 1943 : The Battle of Midway PCB :
This latest revision worked fine on all other PCBs I could try (including Pang, Super Pang, Block Block, Side Arms and Poker Ladies) except Black Tiger where glitches are present :
This problem apart, it's nice to have a working replacement of this unreliable custom IC.A huge thanks again goest to 'furrtek' for his invaluable work.
