So this basically translates DirectDraw calls to Direct 3D? Or OpenGL?
Either way, it would be fantastic news for old games not working properly in modern systems! I don't have the time to test it out, but thanks for this anyway 😁

no. It is just a pass thru to ddraw

I you want a rewrite look at wine

Nice one, will prove useful. Thanks

Wine translates the calls to OpenGL right?
Could you explain what you mean by " It is just a pass thru to ddraw " ?

Short version: it changes certain flags when programs call directx, which results in more compatible behaviour.
long version: it does more, but read the source, it's included.

Cool, thanks 😀

This is cool.

There's a reference to "Axis & Allies: Iron Blitz" in the source but I'm guessing there must be several other games from the late 90's that'll work or work better on modern Windows using your wrapper.

Do you have a list of titles? I don't know any DDRAW-only games.

If you prefer to keep a it a secret and let people discover this for themselves that's fine with me though! 🤐

the reference to Iron blitz is for a bug that I have not fixed 🙁
however, I have created a patch for Iron Blitz ( that isn't done yet ) but should be enough to get it running. here

The fixes should be fairly generic
I don't have a list of ddraw games

Force Direct Draw Emulation + Fake Vsync should be tried for any ddraw game that doesn't run, is glitched, or runs too slow
( used it to get Cyber Gladiators running the other day )

Limit Process Affinity - is not for a ddraw issue but it is useful to have applied to games of the ddraw era ( smack videos played by Axis & Allies )

Blt Mirroring is used by infinity engine games like Baldur's Gate 2

Full swap flipping - fixes a issue with Planescape: Torment

Stolen palette fix - works for Diablo: Hellfire but may not work for other games such as Epic40k: Final Liberation

Thank you very much Aqrit.

If it were possible to use it with «Wine» — had be great! 😀
I play to «The Hell» (Diablo I Mod) from Linux and had tired always to use monkey patched «Wine» for normal game.

It is possible to write that cross-dll's for wine and native windows system?

Why not just fix Wine?

If you had wrote the patch, that will be accepted by «wine team»… 😎
That's «monkey patch» allows you to play game, but not well:

• Can not be used last version of wine.
• Wine sources should be patched and builded manually. (But for that i have own ebuild) + Time, spent for compilation.
• Games still contain some problems/artifacts.

Why don't you just try aqrit's wrapper with wine?

Because him wrapper doesn't work with «wine».

Did you try? Why shouldn't it work?

for Wine set ColorFix = 0 in the config file
( edits an internal ddraw struct ... defined by a wine header )

Nothing here will help get Diablo 1 running in Wine

The only patch that might be of interest for Wine is the
RedundantFlip. ( not needed on my PC ) Might be caused in wine by a buggy driver?

I'm not very familiar with Wine so to make sure the proxy dll was loading I just renamed the dll then hex edited the IAT of the target game

Yes. See backtrace…
As Aqrit wrote — problem in "ColorFix" option.
With ColorFix = 0 — game launches successfully, but he doesn't have positive effect for Diablo I. 😒

I'll checked — dll been loaded successfully.

Still around HellDog?

The Wine Appdb for Diablo has 'that' patch for the current source (check the comments)

I've added a similar hack to the proxy dll which leaves Hellfire
still broken but it gets the menu's back ( kinda ) while still retaining the intro movies

set Wine_Diablo = 1 in the config file

---

other changes:

ColorFix now defaults to off

Now wraps the clipper object to keep it from crashing when it gets passed a wrapped directdraw object

Hi, this wrapper is a great thing, i use it for "Horse and muskets ". Would it maybe be possible to
update it for "open general" . At the moment the game does not start with the wrapper.
http://sourceforge.net/apps/mediawiki/opengen … title=Main_Page. By the way, has this
wrapper a antialising effect ?
A big thank you for this outstanding work.
