Unblitz c/bbs Cyborg Cbase

Since i tried almost every unblitz i could find without any success i am asking here.

Does anybody probably have the unblitzed c/bbs file from Cyborgs Cbase ( C*Base Cyborg Modded )or maybe a deblitzer which isnt listed here ?

There is still a very annoying bug which crashes my bbs while listing Uploads in the uds. If there are more than 255 Files inside the Dir the BBS crashes and i`d like to fix this.

I should have that _somewhere_ :) Not sure whether I even already transferred the disk.

Tried iAN's Blitz/Austro Decompiler V3.1 ?

Even tried to work around that specific problem on villain mod for Forplay, btw. Listing contents of a SCSI 2 GB tape drive never worked out properly :)

I already tried in the past that one, I was asked already what's wrong with it and I have no idea =)
boot prg can be decompiled with no probs, but the other modules C/BBS, C/TERM, C/MIDNIGHT (which have to be manually merged with the main boot file with cld or cbmcombine for example) at some point result in bad lines containing garbage.

perhaps shawn used a custom modified blitz! ... that would make it kinda hard indeed

The thing that's causing the deblitzing problems is the basic extensions that C*Base uses.

No time to investigate, so from memory - maybe iAN can validate it:

AFAIR the basic extension used on C/BASE had @ as the leading sign for special commands. Some however had "arrow left" to start those (or was it the other way around?). Whatever unblitzer is used "just" needs to parse basic commands starting with either "arrow left" or "at" as normal petscii until the next colon (":").

I cannot currently find my changed de-blitzer back which was able to handle cyborg modded c*base and such :( - pretty sure though the above sentence suits.

You still have the chance to intercept using the basic vectors as well, Mario. Though I admit a simple SYS in the basic source at the right place is more elegant. Then again: cleaning up a re-compile of C*Base to be somewhere near the original or any roughly commented source sure sucks as well.

Cbase used Plum's Blitz to handle the extra commands in Cbase. Not sure if there is an unblitzer for it.

I was looking into this a little tonight. Being very unfamiliar with ian/hf's deblitzer, i did some unsuccessful mods to the basic source.


my theory is that, if deblitz encounters an invalid basic operation (like @), couldn't deblitz add a "rem " in front of that command and interpret it as a rem'd basic comment, which theoretically would pass as valid basic. Then, after using basedit or similar, load in a text editor, remove all instances of "rem " and the program listing should look correct.

Maybe someone who knows the source better could tell me if this is a valid idea worth trying.
