s16b E-SWAT: glitch prevents advancement on stage 9 #172

Closed ryanfb closed 1 year ago

ryanfb commented 2 years ago

Loaded up E-SWAT (set 4, World), playing through with default DIP switches, I noticed that once I got to stage 9 and advanced there's a sequence where enemies on trucks are supposed to appear, however, the first one glitches out, the rest don't appear, and you wind up stuck and unable to advance on a screen with no enemies.

Here's how the sequence is supposed to go from an arcade LP: https://youtu.be/1Bk04N-0ZLM?t=503

I confirm this glitch.

I thought it could be the same as jotego/jts16#5 but tested it on commit 40b01df and the problem is still there.

This happened to me last night playing it on my MiSTer FPGA, i saved a clip of the glitch: https://www.youtube.com/watch?v=yWaerfIBvb8

I also encountered the same issue earlier today.

In addition to my last post I have just tried the alternative core (Set 1, Japan FD1094 317-0131) and I did not encounter the glitch on stage 9.

Just replicated the problem with sets 3 and 4.

Fixed. The sign of the multiplier was changed, before was unsigned. Now the multiplier is signed.
