There is no "conversion". The RAR contains the ISO inside it, R00 (and any further Rxx) files are simply subsequent parts of the archive. You can use WinRar or 7-Zip to decompress it.

Then I must be doing something wrong, as 7-zip informed me on the first go that there was an error - CRC did not compute, or some such. I cannot imagine why a checksum error would have occurred, so I could use some advice.

EDIT: Repeated process after making sure that all files were present. Received this error: CRC failed in 'RLOFT_V1_1.img.ecm' File is broken.

caveat: although I think I did it the first time, I believe I did not include a system information file this time. Should that be included?

EDIT 2: tested the rar-open with all files present in a folder except for cluebook and manual. Used both 7-zip and Peazip; encountered the same error.

EDIT 3: Ok, it works. I obviously was not thinking it through, as a failed CRC on a file should have prompted me to check for a corrupted download. Used 7-zip to complete download.

Most likely culprit is a truncated download. The first archive should be 50 000 000 bytes long. The second should be 48 460 147 bytes long.
There seem to be issues with downloading the second archive; several attempts from me ended up frozen or truncated.

No and no. That's mostly irrelevant to the issue at hand.

Only extract the RAR and ZIP files. NFO and SFV are not archives.

There are several possible explanations here - bad RAM (altough you'd probably experience random crashing in that case), failing hard drive (again, there are symptoms you'd notice) and faulty download. Try redownloading the files, perhaps using a different download tool (or browser, if you downloaded them through one).

Quick question: Do I need both the RAR and R00 archive for this game, or are they just both potential ways to extract the .ecm to get the ISO?

You don't need to convert the .img file. It will work just like an ISO in any mounting program and dosbox's own mounting system will be able to use it.

[JackOLantern]

Alright,

so do I then just run it as -fs fat format? I got the .iso to work, but not the .img. Obviously, It will not mount it as .iso in .img format. Also, on a related note, will games automatically read from a imgdrive mounted as D, or do I need to do anything to ensure that files of D can be referenced by the ravenloft application?

No. FAT filesystem does not have anything to do with CDs.

Less than intuitively, -t iso covers ISO, BIN and IMG formats. If mounting the image is not working, a screenshot of the error message would be appreciated. According to DOSBox wiki, it also supports loading the images using the CUE sheets - if there's a CUE file together with the IMG, try mounting that instead. As a rule of thumb, you don't normally need to use the -fs switch.

[DarthHelmet86]

How are you mounting the image? Are you using another program to mount it to a virtual drive? Or are you using Dosbox to mount the image itself?

[JackOLantern]

I am not using a frontend to mount the drive; I am just trying to mount the rloft file to the D drive as IMGMOUNT. Unfortunately, when I do so as an ISO, the files do not appear to be accessible, and it does not recognize the .img as its own directory right now. The iso itself, however, can be sort-of-mounted with IMGMOUNT D [INSERTDIRECT]\File.iso - t iso

This command is not useful, however, right now...

EDIT: I see now why the ISO file would not work - I did not convert the file, I just placed the file in an ISO wrapper - useless

Mounting the .img as disc would probably be a better solution since my .iso file is not really a .iso file.

[DarthHelmet86]

The easiest way to do this would be to use a program like Magicdisk or dameontools lite or some other similar program to mount the image file as a virtual drive. Once that is done you just need to mount that drive i.e. mount d g:\
