Ready modification soft like OCLplus or MoO2 Workshop, of course, but what is used for primary research ?
I tried hex/code editors Hiew and Biew and data interpreters StructLook, Structorian and DataWorkshop. Counterparts in either group have their weak and strong sides, but IMO archaic StructLook looks better when we have lots of bit-flags.
I propose to use StructLook format (until something better will replace it) for keeping all discovered data in one text file and keeping it up to date instead of spreading offset lists through entire forum (i searched for word "offset" here, some lists are raw and could be updated even using years-old OCLplus data).
Recently i wrote structure-definition file for executable (Lord Brazen's UPatch 1.40b23) and savegame, initially based on information taken from OCLplus, Corion2 and some savegame-comparing. Right now i update it with discoveries published here on forum and code-viewing those places (e.g. it makes evident where's Guardian's first Special - Auto Repair Unit).
Let's hope that way we can do more.
- Hiew - commercial/demo (not "trial"); author's page
- Biew - opensource; SourceForge page.
- StructLook - old abandonware (by SEN, author of Hiew), still hosted here and there. stl430.zip can be found and downloaded, (to prevent surprises: mine has MD5 = b771029fefe5038281e5281c037de0be). I use it under DOS session (NTvdm), not even DosBox.
- Structorian - freeware/opensource, old at author's page, new (C# ) at Google Code project page.
- DataWorkshop - free&open, product page or project at gna.org.
- JojoDiff - free&open; SourceForge page; Xdelta - free&open; home/blog. Not exploration tool, but good to make (and apply) distributable diff-files when mod is done.
P.S.: to Lord Brazen: BTW, i turned to MoO2 on new level at all because of your UPatch, thanks for great work. Your site was very helpful, as i downloaded bunch of editors there as well (and so has good start for analysis). So actually it's yet another echo of your own work, thanks once more (i like .StL-ing things through).
P.P.S.: where i can post it when it's updated ? It's plain text > 50k or ~16k in gzip.
