Re: SuperCharge Decompiler

Interestingly, I don't actually have any explicit RETRY_HERE commands in my source program :-) Yesterday I had a first attempt to start a decompile of the 'xwords' program. And I have found a few differences in the Turbo code V5.35 to my V5.10 that I have been using for development. Causing problem...

Re: SuperCharge Decompiler

Evening Gents, I've been following this topic with interest, but it suddenly struck me, we have the source code for Turbo - is it not possible to work out the information required from that? Just a thought - I could of course, be barking! Cheers, Norm. I did have a very, very quick look at the sour...

Re: SuperCharge Decompiler

Actually, in my first pass against this job disassembly, I found a couple of instances of the JMP $00(a6,d0.l) form, but many of the JMP -<offset>(a6) form and it is the later than proved to be successful in decompiling thus far. All I meant to say was that in the provided version of TurboProcessDu...

Re: SuperCharge Decompiler

On a side note, I've already found at least one duplication of routine (ID: 204 - "RETRY_HERE") that appears twice in my disassembly (so far), only with very slightly different offsets for the BCC and LEA instructions (due to position-dependence) The bcc's are the same, both $6404. The LE...

Re: SuperCharge Decompiler

One question for you - given that the line-start marker generated by v5.37 appears to be "3E1D" rather than the "3C1D" for v5.1 as in the current version of ProcessDump, I note that later in the program an explicit reference is made to the new line-start marker (line 5210 -> &qu...

Re: SuperCharge Decompiler

However, ALL the line-number references in the _codes file report as '-1', whereas I know that the job was compiled with line-numbers enabled, so still something amiss to work with Turbo v5.37. This will happen, as none of the routines checksums in the Library2_id file will match the checksums in y...

Re: Super/TurboCharge Decompiler

Hi Martin, The source to Diskmate 5 is lost and only the Turbo compiled executable exists. I was trying to rewrite Diskmate 5 based on the way it works. I have extracted some of the Easyptr menu definitions, which were added to the end of the Turbo compiled code. Maybe your discharge programme coul...

Re: SuperCharge Decompiler

My first attempt at running (Turbo)ProcessDump against one of my Turbo compiled apps failed to recognise my version of Turbo (appears to be v5.37). The version number appears to be the version of the part of Turbo that creates the final executable, rather than the version of Turbo itself. My versio...

Re: SuperCharge Decompiler

Is there any value in my applying your decompiler to some of my own TURBO'd routines and comparing against my source - feeding back any insights here? It would be nice to get some feedback as to how easy/hard people find trying to use the decompiler. And how close it gets to the original. Note that...

Re: Super/TurboCharge Decompiler

Here is preview of a decompiler for TurboCharge TurboDisCharge.zip It's not complete, or working completely right. But it hase produced this tools.zip From this program http://www.dilwyn.me.uk/tk/Tools_v1_10.zip by Emmanuel Verbeeck. The original program was compiled without line numbers, so the dec...
