launcher GUI with J-shipedit

J-shipedit only reads first 125 lines of database.txt all other line are ignored.

That's a pity. I suppose this limitation is not easy to change? I'll have a look into the code using IDA-pro. Your download link is broken:

here is working vanilla
to use
just add difficulty folder to vanilla install path
open difficulty folder and execute start.exe

vanilla.zip

note; if J-shipedit is used (slider, or upgrade) J-shipedit does not revert back to original settings until J-shipedit is opened again and make no changes to slider/check boxes

It is a UPX compressed executable. To decompress, use:
https://github.com/upx/upx/releases/dow ... -win64.zip

On the commandline then decompress with:

Code: Select all

.\upx -d .\J-shipedit.exe

Makes it alot easier to analyse and fix the executable.

The IDA code looks like one horrible huge messy routine.
And there seem to be multiple hard-coded loop iterations for 125 ships.

E.g. see:

j-shipedit-counter.jpg

j-shipedit-limit.jpg

j-shipedit-var_57C64.jpg

Looks like even if patched, it'll remain a B194 only tool. And by the horrible implementation, that's probably for the good.

edit: note: mov ebx, 7Dh above is encoded to BB 7D 00 00 00 and likewise for all other locations above,
so it is not signed byte limited, which makes patching it alot easier

Thanks guys, I will check this out.

Yeah, back in the day Joker compressed everything. When ornamental fishes suck a pebble it was probably once a cake compressed by Joker....

Sounds almost as if we could just use the hex editor replace function for all '7D 00 00 00' -> 'FF 00 00 00' in the uncompressed file.

Most likely yes, but without further fixture I think you will have to add another 130 ships this case.

I am done... (washing hands now)
