Summary 09465: ct486 [dune2 software]: Rare freezes on Dune II last mission (sblaster_16)
Description This happened to me only two or three times for an entire playthrough (segmented, played over a few days. Host system turned off/on for each new segment recorded), and only on the last mission.
Steps To Reproduce mame ct486 -hard1 msdos622 -isa2 sblaster_16 -board3:ide:ide:1 cdrom -ramsize 16M
Use either -state or -playback, with attachments (save state, or inp) I've provided.

IIRC I used sblaster_16 instead of sb16_lle because Dune II would not cooperate with the latter.
SB configuration (config.sys): SET BLASTER=A220 I5 D1 H5 P330 T5

I have attached:
A) a floppy file (mdi) containing a game save, but I think it is useless, I couldn't reproduce the issue simply loading a previous game save after a "cold boot" of the game. The bug seems bound to something runtime related
B) attachments needed to reproduce the bug.
a) a save state made just before the second freeze (it will trigger the bug)
b) an .inp (used to produce the save state) that goes from booting the system, to a first softlock at the 1:01:46 mark (I managed to exit to DOS), then a second one at the 1:02:43 mark (after restarting a game and loading my last save, without restarting the whole system)
c) the nvram file (ct486/cs4031_rtc)
d) I can NOT attach the msdos622.dif file required for playback / savestate load, because it exceeds the 4,000KB limit. Here is a link: https://mega.nz/file/PexTRTZA#fBtlV-4t6e31TczIJL_lPHjlzc6k15njUYAvvUktThY
Additional Information Here is a video recorded from the inp:

It plays for longer than the inp, I went on playing after it finished.

I have also noticed a bug in the game where destroyed buildings would keep getting displayed.
This can be seen at the 1:39:07 mark on the video. I don't know if it is a BTANB.
