Original The Binding of Isaac (DirectX 9) wrapper injection does not seem to work

[jan-kleks]

I am talking about the original classic game: https://www.pcgamingwiki.com/wiki/The_Binding_of_Isaac It is listed as a DirectX 9 title but dxwrapper does not seem to work with it (e.g. setting up the frame limit or v-sync), also RTSS does not show the OSD.

If this game is a DirectX 9 game then you can use the d3d9.dll stub along side dxwrapper.dll. Just make sure to enable the EnableD3d9Wrapper option in the dxwrapper.ini file. Then when you run the game you should see a new dxwrapper-xxxx.log file.

@elishacloud Yes, this is exactly what I am doing. But there is no log, maybe the info about the DirectX 9 support is incorrect, or the game is doing something unusual, I dunno... Anyway, if you ever have a chance to look into this, it would have been great -- The Binding of Isaac is the cornerstone of indie gaming after all.

Keep up the great work!

If you aren't seeing a log it means that the game never loads d3d9.dll from the game's folder. Either the game isn't a Direct3D9 game or the game is directly loading d3d9.dll from the System32 folder. In that case you need to use a different stub.

Try using one of these stubs instead: dinput8.dll, dsound.dll, d3d8.dll, ddraw.dll, winmm.dll, etc.

You can tell if the game is loading dxwrapper because you will see the log file. Keep trying different stubs until one creates a log file.

@elishacloud If I use winmm.dll and d3d9.dll stubs with EnableD3d9Wrapper the log file is created (attached). But I still cannot control v-sync or FPS.

dxwrapper-isaac.log

Try using only the winmm.dll stub and/or enable D3d9HookSystem32 option in the dxwrapper.ini file.

[jan-kleks]

@elishacloud I have tried D3d9HookSystem32, and this is what I get in the log when enabling Direct3D9Ex and D3D9On12. But I still can't get any visual result.

dxwrapper-isaac.log

[elishacloud]

From the log I don't see any rendering happening in Direct3D9. There is no surface creation, no texture creation, no buffer creation, etc. Maybe this game uses something else to do the rendering, like glide or GDI? Or maybe dxwrapper is loading too late to capture the creation, though I doubt this since the game would almost certainly crash in this case? If the latter is the case than the only solution is to find a stub (besides winmm.dll) that loads earlier.

the original binding of isaac is a flash game.
