Saved Game Editing source code (GFA)

Postby Mug UK » Tue Mar 15, 2005 8:41 am

Hi!

I uploaded a while ago a selection of GFA based source code for editing saved-game files.

Has anyone had a crack at doing their own yet or is the task still a little daunting?

If it is too daunting, I'm requesting a volunteer who can spare some time to play a game (hard work, I know!) and continually do saved game files (please no raw data disks just yet) ...

But before you all send me buckets of .ST files with your data on it ... I'll need some info.

1st - name of the game.

2nd - a description of each saved game. Yes I know it's a pain, but sending me saved game files without any extra info means it's a pain in the rear end.

E.g. What level you're at .. what stats are for your character at this point (e.g. money, health and such like)

Especially useful if you send me a "before & after" saved game - save it before you get an upgrade/sell some items and one after.

when you have got a few saved game files and the information above, get in touch via a Personal Message on the forum and we'll see what happens next.

I intend to make the saved game editor and comment as much of the source code where possible so that others can benefit.

This is a project anyone can help with, but please don't turn this thread into a "can you write a cheat for xxxx" as that's not the idea. The idea is to give you the proper tools to do the job yourself!

I've now got the full version of Pure Basic on my PC, so any esoteric games which use disk images can also be hacked under your PC instead of via STEEM if necessary.

The only caveat will be that any disk image must be in the uncompressed .ST format unless I can convert ggn's code to Pure Basic for opening MSA, DIM etc.

Back when I was playing Amberstar I was toying a lot with the saved game using a hex editor and had compiled (on a a4 page) lots of offsets for all stats, items, gold, etc. Has this already been done? Or should I go and try to find that page? (mind you I dunno if I actually have it, but chances are good).

BTW: if you have any problem converting the DIM (sorry, no MSA) program give me a call! Also, you could use the command line program MSA2ST.EXE to silently convert the images to .ST, process them and then back to .MSA with ST2MSA.EXE.

I'd left the ST before Amberstar came out if memory serves, so nope, saved game editor for that one never done by me.

Either nick my code if you can find your A4 or we can do it as a project?

Mug,

Found it! And well preserved too (except for the fact that a small part of the page in the right is missing!)

I remembered vaguely (and now I can confirm) that it's a big table of offsets, some are missing. That's because I was too lazy to find all offsets for all players (6 in total!). I gather that if I could find exactly where each player's data begins, it could be pretty complete (yes, I was too lazy to find even the starting offsets for each player :))

Since it's a bit big table, I guess I'll type it on Excel and post the file here.

And here it is.

Some notes on it:

a) Sorry for any typos or errors!
b) (w) means word (2-byte) data and (b) means byte (1-byte) data
c) (w/w) or (b/b) means that there are 2 values to fill: the first is the current and the second is the maximum allowed.
d) As the page is missing some text, some data on the 6th player are missing.

Anyway, I never bothered to make a complete editor for it, I just loaded the saved game in Harlekin (very cool hex editor :)) and changed values :). With a few subtractions (which I was always too lazy to do!) you can fill in the missing offsets I guess.

Lastly, make a backup of the saved game file before doing any changes!

Nice one ggn .. if only others were this organised (or even bothered!) :-)

Back in the old days it was literally scraps of A4 / A5 graph paper from Slasher Bog of the Bog Brothers who kept me in saved game editors.

Pity we fell out over a scratched CD of warez approx a decade ago. Ah well, was a good team whilst it lasted.

Sorry for the mess it's in :)

I still also have a a4 page with all trainers I did with bugaboo and was too bored (and igornat ;)) to turn them into complete trainers :)

A CD a decade ago costed a fortune, I think it was a big deal back then :)

No excuse now .. not short of the odd bit of source code here and there. Every game should be cracked and trained (where feasible) ;-)

Yep, had to give him two to replace the one that got scratched by a mate (who didn't last much longer as a mate due to the crap he'd caused!).

C'est la vie.

Well, I doubt if anyone could do much with that list... They way those trainers worked was this:

a) Load a specific version of Bugaboo at a specific address, if the game was in executable form.
b) Get past the loading/depacking if needed (note that I used the games' versions that I had back then, automation etc)
c) Go to the offset I had written down on the paper and change an instruction or something like that

It was much easier for me to play my trained games like this rather than to redo everything from scratch :). Well, I did make some trainers, but I had a very silly loader written in GFA BASIC for that task (read a script file from disk!) that, the more I think of it now, the more ashamed I am :oops:

Still, the only good offset to be found in this list is the breakpoint to be issued to the 'Ooh crikey wot a scorcher' bootsector, so that the protection is bypassed and the hidden screen accessed! (one of the few things I am happy to report that have hacked :))

Populous Save Game Editor

Postby AtariFan » Wed Feb 15, 2006 4:42 pm

Hi,

I remember using a fairly basic save game editor for Populous many years ago. It was published as a GFA basic listing in a German computer magazine.

You could choose to set mana and another value I don't remember ATM to maximum.

If anybody is interested in this small tool, I could look through my disks and post it here.

I got one done in AMOS on the Amiga on my site, so a GFA one would be most welcome :)

Populous Save Game Editor

Postby AtariFan » Thu Feb 16, 2006 6:11 pm

Hi,

I didn't manage to find the source code, so here is the compiled editor.

After starting the tool just select your Populous save game (*.GAM) in the fileselector. Now three options are available:

1. full mana
2. change custom made worlds to conquest worlds
3. 1. + 2.

After pressing 1,2 or 3 the changes are written back to the save game. Now start Populous and load the edited save game.

I still own the magazine where the GFA basic listing was published. If I find the listing by accident, I could post the source code here.

Shouldn't be too hard to adapt my mates old AMOS source code etc.

If you can find the old magazine and scan in that page, it'd be a lot easier than starting from scratch :)

Populous Save Game Editor Magazine Scan

Postby AtariFan » Thu Feb 16, 2006 9:01 pm

Hi again,

I remembered that the listing was published in an old issue of ASM (Aktueller Software Markt) and found it!

The scanned page contains the Atari ST listing in GFA basic 2.0 and the Amiga listing in Amiga basic.

Won't be too hard to make it into a better editor with music etc. in it .. will also see what my mate did in his AMOS routine as I think he added some extra codes in to his editor.

Thanks for the scan :)

Hi muguk

Any chance your offer of making a editor is still open and if so could you could make a Civilization save game editor, I have started work on the SVE format, I’ve attached an excel file, the second tab shows the function, the first tab is a look up table, the third tab shows which bytes I’ve worked out. The fourth tab isn’t used yet as I am having real problems working out the MAP format. Hopefully the file is understandable.

Shouldn't be too hard .. will see what I've got project wise this weekend .. might just be a simple hack job first and then work out other bits and pieces in a future version.

Or get it so far and then hand over the source code to others :)

Just found a development disk in amongst the ones that were "on holiday" @ Makedisk author's place for the last 5.5 years :)

Here's a disk I was working on (no idea if it did get sent to Budgie or not) but there's GFA source code for a few cheats I don't remember writing but I obviously did :)

I've no idea (without comparing source codes) what upgrades I might have done, but I already noticed it's a "work in progress" disk as the Roadwar Europa cheat still has the screen from the Sim City cheat :oops:

Cheat source code for:

Battletech
Demon's Winter
Motor Massacre
Oil Imperium
Roadwar 2000 (or is it Europa)?
Sim City
Star Command

Plus some dodgy old intro with .MOD playback in it .. if I can find a master disk with the compiled versions on, I'll upload that too.

Would it be OK to include it on my site along with the Amiga editor that my mate wrote all those years ago?
