I haven't done anything with ver 1.4 so I can't answer. It's best to save the state just before a "bug" happens and ask bifi. Edit: something that happens only on an emu but not on real MSX is not a bug.

Show it in openMSX, share the replay and we can take a look. That also tells which machine is used.

Do we have a video on real MSX of version 1.4?

Even if the game works on webMSX or blueMSX, if the game bugs on OpenMSX, it certainly bugs also on a real MSX. OpenMSX emulates hardware better than other emulators.

My latest playthrough didn't have the grenade glitch, but it did have the Campbell glitch.

I spent many hours of precious holiday to get to Night Sight boss. For convenience, savedata disk image is here. What to do after F5 -> Load,
SNAKE1: get on the elevator, leave at 30F, fight Red Blaster SNAKE2: from 1:09:47 here
I don't have any device for playing 512KB rom on real MSX and I haven't set up openMSX so I tried WebMSX. No difference at all with Red Blaster. But to my surprise, yes Campbell's face shows up during the conversation with the fan prior to Night Sight boss. Such doesn't happen with original but does happen with v1.2. Needless to say it's not happening in the youtube video.
Theoretically this is very unlikely to happen because I remember the face and who-is-talking are tied and something like Holly speaking with Norden's face cannot be done. One possible reason is since the fan's face is supposed to be blank, nothing is copied to the face box and previous Campbell's image is remaining.

About "the grenade glitch", can you specify more details from your memory?

Another error like thing; once I punched a dummy-guised solider (36:48 here), he seems to have died with one punch but his image remained on the screen and I could not punch him anymore. Whether this is error since from the original/added by translation patch/caused by emu/only my misunderstanding is unidentifiable.

You can make one for relatively cheap. About 350 yens for the FlashROM and less than 3000 yen in japanese shops for an SCC cartridge. An example on Yahoo Auctions:
https://page.auctions.yahoo.co.jp/jp/auction/h411872099

It's easy enough to do: Making A MegaFlashROM SCC of 512kB

You will never be sure that your programs really work if you test them on emulator only.

Earlier I tested my programs only on emulators and I realized that it was not enough although nobody reported the bugs. A majority of people probably use mainly emulators or OCM.

Thanks for the tip and I remember reading it earlier. However I am not in the mood to spend money and effort. I was not involved in the versions later than the initial release which didn't yield this kind of error, so, honestly am not interested in debugging the later versions. I guess it's much easier to find someone who already owns MegaFlashRomScc.
...I own a Rookie Drive but it's semi broken since 1 month ago. Can it do the same? I also have an AddRAM external 4MB ram.

Found the year 2011 video showing the bug from 0:40. I contacted Bifi. Edit: I confirmed this bug also happens on the oldest copy I have. Is my memory faulty or is it emulation?
More edit: I noticed the Campbell face bug does NOT happen with the ancient stuff, Disk version MG2. Neither on the emu nor real MSX. Screenshot and video here. PIN: diskrules Does this suggest any clue why it happens with .rom?

I beleive bug with Campbell caused by line that usually slowly scroll down. Since there is no image intended
when fan is calling, the line is not moving and causing the issue. The windows suppose to be black without line ever drawn.
And line is at random spot or at the coordinate where it finished with previous person who was there..

Yes, the face display is behaving differently from other time the Fan is talking.
Bifi since replied me that this glitch does NOT happen with real MSX. So it's probably emulation issue. I tried a different emu, RuMSX but the Campbell face always shows up regardless of the configuration (MSX2, TR800, Old2Plus...).
