Oops! :woozy:  Here’s the context that led me astray: post #928 of “Classic99 Updates”.

 

 

You’re most welcome.

I'm obviously becoming more forgetful.  :)

This is a great project and effort Lee!

I tried my ways once to recreate a commented version of the console rom / groms for the 99/4a by starting from the 99/8 console source files, which were released.

The "official" comments by TI are a great ressource. The 99/8 console rom can be considered to be identical over many parts, so the comments can be "moved" over to a disassembled 99/4a rom/grom file.

Diff Tools like WinMerge [www.winmerge.org] are essential for such a comparison project.

I also tried to align the sourcecode with Intern to include his comments.

This is another source i discovered already on whtech:

ftp://ftp.whtech.com/source/console.src

The 99/8 source files are in the same ftp-directory.

 

I also discovered another ressource for commented source files inside the Genie.

Here is all what I have so far. I got sidetracked by some other "interesting" thing.

Maybe its of help.

In the last days I have tried to prepare a merge of these two files by adding comment lines to the file if the other had a code or comment line to achieve a better diff comparison. It's not finished yet, but once it is, the extensive original comments from the 99/8 source code [intsim.txt] can be moved over to your work file [ROM-4A-a.a99] quite easily.

Unless I made a mistake, the ROM-4A-a-comments.a99 file should still generate the same binary output.

 

Whenever I added a line, i did it with "****".
