Walls of Rom (1443)

While noticing some glitches in the TDC version of the game, I was comparing the floppy content with the TGOD matching images I had. What was noticed is that the fillers for the TGOD image were 0x00 instead of 0xF6. I experimented with some older images that were incomplete (i.e. 1994 .imz data files), and once imported into a new WinImage and saved back, the missing data was filled with 0x00. Specifically 0x119400-0x167FFF (Sector 2250 - end) for this disk1 for example. Unused, clean formatted data is supposed to be 0xF6 (like #2973).

Is something like this happening here where someone is completing a disk that is short in bytes or is that taken into consideration when receiving images that someone may have changed?

What that tells me is that #1443 is really bad when compared to #2973.

Incomplete how? You mean the unused part was truncated? It is possible that earlier WinImage versions did something like that, yes. I remember some DOS app, which did pretty much the same thing. However, I'm not really sure we're dealing with the same exact aftermath here even though it seems to coincide. I've examined plenty of dumps to know it is always possible to have the same version but different release, which can be slightly different in all kinds of delicate ways, so I'm afraid so far it doesn't prove anything. But hey, note taken!

I have several old truncated disk image .IMZ files I found dated 1994 (I think I got from the german CGBOARD) which, if they used WinImage, could have removed the remaining F6 as saving space. I will have to use a v2.0 WinImage if I can find it to see if that was its way of "compressing" back then.

Edit:
Found it. The default option was to truncate the image. See pic.

Thanks, only I still don't know if I should mark this set as modified. I mean, what are the odds that this other person did exactly what you did? Maybe it's WinImage, maybe something else. But one thing I will definitely do is write some notes.
